Abstract
On planet Earth, instead of first studying simple, economic and sustainable solutions, men in power have always fomented wars to dominate neighboring countries, developing offensive energy instead of peace and coexistence. As I have written in all my articles, thermodynamics and then nuclear energy were preferred to fluid dynamics to become increasingly powerful towards other countries and to be feared in the event of wars, without taking into account that nature uses heat and nuclear energy only in the nuclei of stars and planets, where biological and animal life does not exist. Where there is life, there is water, air, fluid dynamics and natural electromagnetism, which have only nuclear and thermal origins, which as mentioned, develop at the center of stars and planets. Bipolar electromagnetism and unidirectional gravity are the forces that regulate the circulation of galaxies, stars and planets in the vacuum of space, where it is not possible, as on Earth, to achieve the Newtonian or reaction thrust, which we use on Earth to move with means of transport that use fossil thermal energy.
In fact, it is the combustion fumes that produce the reaction thrust, but at the same time heat the planet and pollute it with CO2, combustion oxides and excess steam. The latter should not be underestimated, as the Earth has its own natural evaporation that has stabilized in 4.5 billion years. Excess steam accelerates the natural exchange between the ionosphere and the Earth’s surface because water polarizes into (OH-) and (H+) ions and increases atmospheric turbulence, while CO2 has a non-polar molecule that tends to stratify in the lower layers of the atmosphere as it is heavier than air. The current earth science of governments and multinationals has not taken into consideration my four international patents dedicated to fixed plants, where I modified the chimneys, the sewage systems, the purifiers and created everywhere limestone greenhouses with artificial rains on limestone materials that would produce carbonates that go towards the sea, instead of CO2, steam, combustion oxides, which rise into the atmosphere.
My national and international patents developed from 2007 to 2013 have all been ignored and global warming has continued undisturbed. However, the experience gained in the design of purification not implemented by governments and multinationals has not been completely wasted. Because I understood that in the majority of cases, we do not need heat to produce energy and therefore purification is also simplified 100%. In fact, the
patents filed from 2014 to 2021 began to produce cold terrestrial energy with the submerged hydroelectric system included. The latter can also be mounted in mobile plants of any size, using only water and air that instead of polluting, purify each other and do not consume by recycling themselves endlessly. These plants can also be built in the vacuum of space by bringing with them the technology and biological ingredients to produce photosynthesis and the carbon cycle, water, air that with the compressed, cold hydroelectric system would produce together the Newtonian and Lorentz thrust in the Earth’s environment, while in space, it would only use the Lorentz thrust. Unfortunately, all terrestrial science is silent on this subject. They are spending hundreds of billions to reduce the size of nuclear plants. Even if they manage to produce small-scale nuclear power, they will never be able to produce terrestrial electromagnetism, which can only be developed cold, at terrestrial temperatures with permanent magnets and thin copper wires painted with insulating paints that cannot withstand high temperatures, but communicates perfectly with the electromagnetism of the original universe produced at the center of the earth, with very high temperatures and very high radiation. We should make some very simple reasoning: if in the current state of the art, science has not yet managed to create engines that could add together Newton’s reaction thrust to the terrestrial electromagnetic thrust of Lorentz because it is impossible to couple this with thermal engines and turbofans. How can we think of coupling Lorentz’s thrust to nuclear engines that produce temperatures of millions of degrees? This apparently impossible undertaking has been solved virtually, without funding, with the compressed hydroelectric system that would allow the creation of fixed and mobile cold electrical plants that are completely energy autonomous. Infatti, le correnti elettriche indotte e i magneti permanenti che produrrebbero la spinta elettromagnetica di Lorentz potrebbero circolare sulle pareti esterne isolate dei turboventilatori elettrici, delle autoclavi e perfino nelle pareti interne dei mezzi di trasporto aeronautici, spaziali, sottomarine.
Current science is not happy with having produced global warming. It wants to completely destroy the planet by continuing to produce steam of nuclear origin instead of that of thermal plants. Even if it could avoid nuclear accidents. The word accident already means that there is a high probability that they will occur. I believe that the entire science is guilty, not only nuclear science, because the entire science is silent on the fact that the cold extraction of energy from the environment has the potential to trigger powerful energetic effects and positive collaterals, purifying, and organizational of world work that would completely eliminate the burden of transporting terrestrial electrical energy in any form. Energy must not be transported but produced locally in a fixed mobile version because the creator of the universe has arranged that we could do it simply by developing technologies in a simple and linear way.
However, at the present time, with the state of the art still at point zero, despite the forty patent filings of the undersigned, it would be sufficient to produce this energy locally with small compressed hydroelectric generators that, by powering heat pumps, already available on the market, would allow us to protect the people of the Gaza Strip, the Ukrainian people, from the heat and cold, who while waiting for their homes to be rebuilt, could live in tents, equipped, precisely, with energy-autonomous compressed hydroelectric energy, which does not need energy transport from thermal and nuclear power plants and not even from solar panels and wind turbines. So, energy would cost nothing except the generator and the heat pump. Unfortunately, this good work towards these unfortunate populations cannot be done because those who have the economic power on planet Earth do not want to finance the experimentation of this simple and cheap energy to continue to finance the usual paid energies that do not solve the current emergency and not even the even more important one of global warming. For this reason I proposed to create an international joint stock company open to all men of good will who care about ensuring a sustainable future for their children and grandchildren. Without wars that are largely fought to supply energy sources that are not needed. Obviously the company must be called Spawhe S.P.A. On this occasion, as I did in the previous article (https://www.spawhe.eu/about-me/) I also publish the IBAN of a current account of the Ing Bank, registered to the undersigned, which is currently empty, so that it can be filled by competent people. Not to do charity, but investments with honest profits, certainly, higher than current profits, as the SPAWHE system has the potential to renew the entire world economy. The IBAN is the following: IT78I0347501605CC0012826539. The objective is the following: The creation of SPAWHE SPA, which aims to experiment and realize all the inventions of SPAWHE. The risk of losing the capital by the investors is zero. Because in the event that, within a year, the fundraising is not sufficient to establish the company and start the business, the collected capital paid will be returned to the individual financiers. In fact, in the payment transfer the following reason must be indicated: Constitution of the company SPAWHE SPA. In the intentions of the undersigned, SPAWHE SPA will be a multidisciplinary joint stock company for the design, testing and construction of fixed and mobile anthropogenic energy and purification plants.
Description
I take this opportunity to publish my old Italian patent filing for sustainable development: 102007901570785 (CE2007A000010) dated November 6, 2007, which found no interlocutors entitled “CAR TENTS FOR SUSTAINABLE TOURISM”
When I proposed this invention I did not know that eight years later, on September 4, 2015, I would have invented the perpetual current generator pressurized with compressed air with water recycling that without fuels could have electrically powered a heat pump to produce heat in the winter and cold in the summer without fuels. Therefore we could have lived even under a tent at the very cold poles and very hot neo-deserts. I didn’t even know that my next invention would be the hydroelectric car with a compressed hydroelectric engine and peripheral driving torque at the wheels on August 26, 2016.
Unfortunately, still in 2025, none of these inventions have found public and private interlocutors.
The ways of the Lord are infinite, but very few inventors have followed alternative paths to the thermal one, since heat is the energy of the universe. Cold energy seemed insignificant from a scientific and technological point of view, but gradually, it led the undersigned to important inventions, such as submerged and compressed electrical energy that do not need the hydraulic jump to produce fluid dynamic energy from the environment to create fixed and mobile anthropic plants, both purifying and energetic. Aside from the enormous economic and environmental benefits, due to the abundance of raw materials such as water and air, I would like to ask the following question to the powerful of the Earth: If these two inventions had found public and private interlocutors, how much sustainable work would they have created and how many human lives would they have saved? Obviously, the hydroelectric car is much more important than the tent, combined with the car, but the reasoning of the combination allows us to create a sustainable development model, as we can make the most of existing state-of-the-art technologies without being invasive towards the terrestrial environment. If today we had developed these two inventions well, terrestrial life would be more sustainable because even the poor could defend themselves from the heat and cold by simply extracting energy from the terrestrial environment and afford to live in the most beautiful places in the world living under a tent because the energy extracted from the environment costs nothing, being the atmospheric air and the gravitational force the energy source, while water is the energy carrier and also costs nothing.
CAR TENT FOR SUSTAINABLE TOURISM
The writer with this project aims to provide people who make mixed use of the car (family, work, free time) with tools that enhance the possibilities of use. The idea was born by identifying in the protrusion constituted by the lock of the rear door, a valid support point for lifting and loading into the car objects of a weight greater than our modest physical possibilities; further observation of the closing space of the bonnet led to identifying in the drip tray for collecting rainwater, which follows its perimeter, a valid drainage system also for the water of a possible camping tent that could expand the living possibilities of the same bonnet; the support of the tent would be entrusted to the same tool designed for lifting the load, with the same support point. We have therefore come to put together two different arguments, but arising from a common intuition and a common basic tool that allows their realization. The basic tool designed for these functions is a telescopic metal rod (for easy transport) equipped at the upper end with a device for attaching to the bonnet lock. By mounting a small winch at the end of the telescopic rod (fig. 1), we allow a person with modest physical strength to lift heavy loads, which would require the intervention of at least two people; by coupling the rod to a track with a translation trolley and to a stand, placed in the passenger compartment, it is possible to carry out the translation and deposit of the load inside the passenger compartment and the subsequent extraction without physical effort. The load translation stand has a second possibility of use: by transforming itself, with simple assembly operations, into a load-bearing support for a convenient two-wheeled trolley, as shown in fig. 4, capable of picking up and transporting the load to the lifting point, before being used for the lifting operation itself. The small size of the equipment designed allows it to be transported by car so that it can be reused for unloading operations.
As of 2025, there does not seem to be any equipment so simple, light, cheap, and versatile that allows a person to load and unload from the car, without effort, loads of about 60 – 70 kg, even if it takes a couple of minutes to assemble and disassemble the equipment. It is nothing more than an assembly kit that can be used as an accessory to load and unload weights. The second function of “tent support”, : obviously it would have required additional accessories, but it would have allowed a more important function than the first one since, as illustrated in fig. 6, it is used to support a simple Canadian-type tent, of new conception that covers the open car bonnet, expanding the living space of the car and allowing a new rational use of the car by campers, street vendors or families for simple trips out of town. By adding an additional pole and a crosspiece, the Canadian can be transformed into a cottage version, with more space. By fitting a sheet inside the passenger compartment, with the seats folded down, two places to sleep in the car can be obtained. For medium-small cars, by adding an extension to the attachment point of the bonnet, the sleeping places can be lengthened up to two metres in length. By adding an additional telescopic structure, a veranda can be supported for the cottage version, or a second external sheet, if you want to add two more sleeping places in the tent compartment created. The “tent” function cannot be universal, but necessarily customized for each car model, but it can use the telescopic rod system designed in a universal way, which adapt to various sizes and take up little space for transport and storage. In addition to the problem of rainwater drainage in the connection section between the car and the tent, which was solved as anticipated by using (as an integral part of the system) the car’s exhaust drip tray, the problem of wind infiltration was also addressed, which was solved by inserting soft PVC pipes into the peripheral edges in contact with the body. The solution solves the problem because the PVC pipe has the right degree of flexibility to follow the shape of the body and rigidity to ensure its adherence under the action of the tensioning ropes (see fig. 12). The “tent system” can be considered an unprecedented combination of the car and the tent, simpler and cheaper than existing systems, which range from roof tents, to tent trailers, to caravans, to campers. The new invention should fit into an empty space (both commercial and functional) between the small Canadian tents, which are mounted on the ground separate from the car, and the tents mounted on the roof of the car (which have not been very successful despite the excellent workmanship of some models) combining the solidity of the car with the anti-condensation transpiration of the tent, without having to climb onto the roof or sleep on the ground, with greater safety with respect to atmospheric phenomena than is permitted by the aforementioned existing versions. In particular, in the house version, the telescopic structures could constitute a natural continuation of the Faraday cage that protects the occupants from the effects of lightning (the conditional is a must, as the appropriate checks are necessary).

FIG. 1 to 5 show the applications related to the “lifting system”; FIG. 6 to 19 refer to the “curtain system”; some components are common. All the elements designed are listed below in numerical order with the relative description so as not to repeat them later in the illustrations of the drawings:
(a) telescopic rod:
(a-1) telescopic rod structure made up of three elements of tubular galvanized steel (or similar) with a decreasing section from top to bottom, equipped with holes for mounting accessories and for telescopic adjustment of the length, variable based on the height of the vehicle to be served. To ensure greater rigidity of the rod, the length will be adjusted by at least two steel pins for each section of the rod, secured with quick-assembly UNI 3545 shaped cotter pins. The upper end of the rod will be rigidly fixed to the lock structure, as shown in detail “A” in fig.1, so as not to stress the same to tip bending, but to transmit the modest induced stress only to the fixing bolts of the structure. Let us see in detail the extent of this stress: suppose that the load to be lifted is 70 kg and the inclination of the rod is 300 with respect to the vertical. As a result of the decomposition of the forces we will have a force that will act along the axis of the rod structure with a compressive bending stress and another that will act on the upper support point, stressing the fixing bolts of the lock in shear.Il valore della Ia forza è il seguente: 70 x cos 300 = 70 x 0,866 = 60,62 kg = 606,2 N;
the value of the IIa force is the following: 70 x sin 300 = 70 x 0.50 = 35 Kg = 350 N.
If we consider that this stress is distributed over at least two bolts, we realize the inconsistency of the stress itself, considering that bolts with a minimum resistance class (3.6 of the UNI EN 20898 standard) have a nominal breaking load of 300 N/mm2; therefore a modest M5 threaded bolt with a resistant section of 14.2 mm2 has a minimum breaking load of 4690 N. Since this is not the place for the structural calculation of the rod, we only wanted to demonstrate that with the proposed solution it will not be possible in any way to cause damage to the structure of the car lock on which it is essential to lean.

The FIG. 1 to 5, are dedicated to the representation of the “lifting system”:
FIG. 1 shows a typical section of a car with the application of the load lifting and transfer equipment. The tool allows the aforementioned loads to be easily lifted, which generally do not exceed 60-70 kg, and facilitates their depositing and extraction from the passenger compartment with the help of a small winch with a crank handle (a-2). The telescopic rod (a-1) rests on the ground and hooks onto the structure of the tailgate lock by pushing the pin (a-6) upwards which releases the lock, the eccentric bracket (a-7) which blocks the lock to the rod is screwed on in order to avoid bending stresses on the rod, it is tied with a rope to the opening hinges of the tailgate itself, and below, to the wedges (c) placed under the rear wheels of the car; subsequently, the load transfer stand (b) is mounted, which is hooked on one side to the rod with the element (b-1), by means of a steel pin, while the opposite side rests on the internal floor of the vehicle by means of the telescopic feet (b-9 / b-10). The load is lifted by the hook (a-3) which passes through the two load-bearing plates (b-1). When the high position is reached, the load is stopped, the translation trolley (b-3) is brought close to the locking pin (b-4), it is hooked with the translation snap hook (b-5) to the rope and the support snap hook (b-6) to the load; the support rope is loosened by turning the winch crank in the opposite direction and making all the weight rest on the trolley (b-3), the suspended load is pushed inside the passenger compartment; Once you have reached the unloading point, lock the trolley with the pin (b-7), tighten the rope by slightly lifting the load with the winch, release the snap hook (b-6), place the load on the floor by operating the winch, finally release the snap hook (b-5) and the hook (a-3). To unload, carry out the above operations in reverse: hook the load (a-3), hook the rope with the snap hook (b-5), lift the load, loosen the rope with the winch (a-2), remove the pin (b-7), move the load outside the vehicle compartment, deposit the load on the ground with the winch. You can then dismantle the translation structure, transform it into a trolley and transport the load to its destination. Fitting the lifting structure to the vehicle takes no more than 2 minutes and the time can be reduced if the telescopic structures are already adjusted to the working height of your vehicle.
FIG. 2 shows the loading system seen from the top and rear of the vehicle with some slightly enlarged details. You can see: view “A” and the horizontal section with the positioning of the stand inside the passenger compartment and the locking system with the ropes (d) and (e); detail “A”, the hinge (b-11) between the arm (b-8) and the foot (b-9) and the position of the gravity pin (b-12); detail “B”, the hinge (b-13) between the arm (b-8) and the track b-2 and the position of the locking screw (b-14); detail “C”, the articulated plate (a-5) with the rope (d) connecting it to the wedges “c” placed under the wheels of the vehicle; detail “D”, the support plate b-10 of the foot b-9.
FIG. 3 shows an axonometric view of the telescopic rod with winch and accessories. You can see: the rod extended, in working position and shortened for storage or transport; the details (a-9, a-10, a-11), necessary for a further, possible use of the rod as a tripod.
FIG. 4 shows an axonometric view of the gantry structure for the translation of the load inside the passenger compartment. You can see: “A”, the articulated structure in the closed position for storage or transport (the open position is visible in fig. (1 and 2); “B”, the structure without the details (b-9 and b-10) to be transformed into a trolley; “C”, the structure transformed into a transport trolley, useful for moving luggage, household appliances, bags, work equipment, etc.
FIG. 5 shows the use of the telescopic rod equipped with a winch with the translation stand described above, coupled with two additional telescopic rods to form an easy-to-transport tripod with many possible uses (think of workers working in road manholes, lifting through attic trapdoors or simply handling equipment during assembly or painting phases in rooms without lifting equipment. You can see: the telescopic feet (b-9) longer than the version used for loading the vehicle; the cable connections “d” of the support plates (a-5); the enlarged detail of the upper connection with the particulars (a-9, a-10, a-11).
FIG. 6 to 19 are dedicated to the representation of the “curtain system”:
FIG. 6 shows three typical side views of the application of a curtain to the hood of cars:
a) low car without extension; b) low car with extension (a-13) to increase the curtain space; c) tall car without extension, which obtains the same result as solution “b” without the need for the extension, taking advantage of the greater height of the car and the greater length of the tailgate. Some considerations can be drawn from observing the drawing: that the system is enhanced by tall cars, with a long tailgate and penalized by low cars, for which the expansion of the habitable space is limited; for these, a solution has been provided that allows for its expansion, represented by position “b”; that the double wedge (c) has been provided in correspondence with the rear wheels of the car to increase the possibilities of tensioning the curtain without resorting to pegs; that the tensioning ropes (f-14) are grouped together to reduce assembly times; you can also note the following details: the position of the rainwater drain of the tent roof and the car roof; the position of the PVC pipe (f-12) to limit the flow of rainwater from the roof towards the tent; the overlapping of the terminal edges (f-9) with respect to the profile of the car; In the following drawings we will always refer to solutions with low cars as they are the most common, although as mentioned above the system is enhanced by tall cars.
FIG. 7 shows a plan and longitudinal section of a car with a “Canadian” type tent. You can see: the overlapping of the flap (f-11) on the open tailgate to limit the flow of rainwater to the roof of the tent; the extension of the sleeping area (f-8) obtained directly in the tent structure and directly connected to the pocket (f-3) for extending the support surface; the alignment of the internal support surface (h) with the external support surface (h-1); the shaped profile (f-6) and the rainwater drainage holes in the drip tray (f-7).
FIG. 8 shows a plan and longitudinal section of a low car with a “Canadian” type tent, complete with sleeping area inside the passenger compartment. You can see many details already highlighted in the previous figures and the details of the connection of the internal sheet (g) with the extension (f-8) by means of the detail (g-8); this connection is eliminated only for cleaning and washing the tent to reduce assembly times.
FIG. 9 shows two longitudinal sections of a car with a “house” type tent, complete with veranda and sleeping sheet inside the passenger compartment. You can see: a) the version with double external sheet that allows for comfortable sleeping even in the tent area, bringing the total number of beds to four; b) the version with a simple veranda and structure without an extension needs no comment. Both solutions require additional telescopic structures shown in fig. 14 compared to the “Canadian” versions.
FIG. 10 shows the plan view of the telescopic structures of the versions shown in fig. 9
FIG. 11 shows the horizontal sections of the versions shown in fig. 9. It can be seen that in the “four-seater” version the feet of the people sleeping in the tent area are subjected to the extension plane (h-1); this is possible without interference with the support feet of the table (h-2), which for this reason is equipped with a single central support, as visible in fig. 12 and detail fig. 19/a.
FIG. 12 shows the cross sections of fig. 9, it can be seen: in section A-A, the view of the access to the sleeping tent (g), the table (h-2) with the central support foot from the front side; the external telescopic structure (a-14) supporting the tent; in section D-D the view of the cottage tent subjected to the external sheet (f-15); the common detail of all versions, relating to the assembly of the tensioning rope (f-14) on the profile of the car with the PVC pipes (f-9) and (f-12), the tensioning of the base rope (d) by means of the detail (b-10) (used in a secondary function, being an integral part of the translation stand of fig. 1-2-5). FIG. 12 shows the cross sections of fig. 9, it can be seen: in section A-A, the view of the access to the sleeping tent (g), the table (h-2) with the central support foot from the front side; the external telescopic structure (a-14) supporting the tent; in section D-D the view of the cottage tent subjected to the external sheet (f-15); the common detail of all versions, relating to the assembly of the tensioning rope (f-14) on the profile of the car with the PVC pipes (f-9) and (f-12), the tensioning of the base rope (d) by means of the detail (b-10) (used in a secondary function, being an integral part of the translation stand of fig. 1-2-5).
FIG. 13 is the same as Fig. 3, the rod (a-1/a) is without the winch and the profile (a-4) connecting it to the translation stand, therefore the rod (a-1) could also be used for the “tent system”. As shown, it can be used to support tents in the Canadian version; for an extended version, it uses the extension (a-13); for the house versions it is integrated with other accessories shown in fig. 14.
FIG. 14 shows additional telescopic structures and accessories, necessary for completing the proposed system already described in the table: a-12-13-14-15-16-17.
Fig. 15 shows the axonometric views of the tents in the Canadian and simple house versions. The details already described in the table and in the previous detailed figures can be identified.
Fig. 16 shows the axonometric views of the tent house with veranda, and of the additional sheet with veranda, which can be superimposed on the simple house in fig. 15/b. The details already described in the table and in the previous detailed figures can be identified.
The sheet (b) with the telescopic structures of fig. 14 could be used without the underlying awning by street vendors who use the car to display their merchandise sheltered from the elements.
Fig. 17 shows the axonometric view of the sheet inside the car. You can see: the lateral openings with zippers to access the inside also from the rear side doors of the car, as well as from the bonnet; the zipper on the wall (g-1) communicating with the front seats of the car; the trunk (g-4) shaped according to the profile of the opening space of the bonnet; the lateral and lower fabric flanges for adherence to the body of the car (g-5-6); the hole (g-6/a) for the passage of the hook for mounting the extension (h-1), the hooks (g-7) for suspending the rear end to the upper drip; the fabric flanges with tear-off felt for connection to the sheet extension (f-8).
FIG. 18 shows the details of the extension (h-1) and the support surface inside the car: you can see: the interlocking composition, without the need for tools, between the components (h-4-5-6-7-8) which determine the support and containment surface also for the slats (h-3); the creation of a space for storing material in the gap created between the floor of the car and the wooden support surface; the trapezoidal shape of the surface (h-1) which follows the shape of the sheet (g).
FIG: 19 shows the auxiliary functions that the wooden components (h) can perform to reduce the quantity of transported equipment: The support (h-2), of the extension (h-1), as already anticipated in fig.9 -11, has been designed with three telescopic supports to allow the extension to overlap with any sleeping places in the tent compartment; the lower support surface, consisting of a table that, when placed on the waterproof sheet of the floor, does not cause damage; in detail (a) it can be noted that this inverted support becomes a small rectangular table; since the size of the table is equal to that of the three slats (h-3) it was planned to couple them together to form a wooden box, useful for containing most of the system components, in particular the telescopic structures, during the storage phase: detail (c) shows the box assembled by means of two head panels (h-9) and coupling hinges, mounted at the head of each board and on the four sides of the detail (h-9); Section “A-A” and view “A” show further details of the assembled case; the same slats (h-3) and details (h-9) can be used to make sturdy stools if coupled with folding trestles, as shown in detail (b).
CAR TENT FOR SUSTAINABLE TOURISM
The writer with this project aims to provide people who make mixed use of the car (family, work, free time) with tools that enhance the possibilities of use. The idea was born by identifying in the protrusion constituted by the lock of the rear door, a valid support point for lifting and loading into the car objects of a weight greater than our modest physical possibilities; further observation of the closing space of the bonnet led to identifying in the drip tray for collecting rainwater, which follows its perimeter, a valid drainage system also for the water of a possible camping tent that could expand the living possibilities of the same bonnet; the support of the tent would be entrusted to the same tool designed for lifting the load, with the same support point. We have therefore come to put together two different arguments, but arising from a common intuition and a common basic tool that allows their realization. The basic tool designed for these functions is a telescopic metal rod (for easy transport) equipped at the upper end with a device for attaching to the bonnet lock. By mounting a small winch at the end of the telescopic rod (fig. 1), we allow a person with modest physical strength to lift heavy loads, which would require the intervention of at least two people; by coupling the rod to a track with a translation trolley and to a stand, placed in the passenger compartment, it is possible to carry out the translation and deposit of the load inside the passenger compartment and the subsequent extraction without physical effort. The load translation stand has a second possibility of use: by transforming itself, with simple assembly operations, into a load-bearing support for a convenient two-wheeled trolley, as shown in fig. 4, capable of picking up and transporting the load to the lifting point, before being used for the lifting operation itself. The small size of the equipment designed allows it to be transported by car so that it can be reused for unloading operations.
As of 2025, there does not seem to be any equipment so simple, light, cheap, and versatile that allows a person to load and unload from the car, without effort, loads of about 60 – 70 kg, even if it takes a couple of minutes to assemble and disassemble the equipment. It is nothing more than an assembly kit that can be used as an accessory to load and unload weights. The second function of “tent support”, : obviously it would have required additional accessories, but it would have allowed a more important function than the first one since, as illustrated in fig. 6, it is used to support a simple Canadian-type tent, of new conception that covers the open car bonnet, expanding the living space of the car and allowing a new rational use of the car by campers, street vendors or families for simple trips out of town. By adding an additional pole and a crosspiece, the Canadian can be transformed into a cottage version, with more space. By fitting a sheet inside the passenger compartment, with the seats folded down, two places to sleep in the car can be obtained. For medium-small cars, by adding an extension to the attachment point of the bonnet, the sleeping places can be lengthened up to two metres in length. By adding an additional telescopic structure, a veranda can be supported for the cottage version, or a second external sheet, if you want to add two more sleeping places in the tent compartment created. The “tent” function cannot be universal, but necessarily customized for each car model, but it can use the telescopic rod system designed in a universal way, which adapt to various sizes and take up little space for transport and storage. In addition to the problem of rainwater drainage in the connection section between the car and the tent, which was solved as anticipated by using (as an integral part of the system) the car’s exhaust drip tray, the problem of wind infiltration was also addressed, which was solved by inserting soft PVC pipes into the peripheral edges in contact with the body. The solution solves the problem because the PVC pipe has the right degree of flexibility to follow the shape of the body and rigidity to ensure its adherence under the action of the tensioning ropes (see fig. 12). The “tent system” can be considered an unprecedented combination of the car and the tent, simpler and cheaper than existing systems, which range from roof tents, to tent trailers, to caravans, to campers. The new invention should fit into an empty space (both commercial and functional) between the small Canadian tents, which are mounted on the ground separate from the car, and the tents mounted on the roof of the car (which have not been very successful despite the excellent workmanship of some models) combining the solidity of the car with the anti-condensation transpiration of the tent, without having to climb onto the roof or sleep on the ground, with greater safety with respect to atmospheric phenomena than is permitted by the aforementioned existing versions. In particular, in the house version, the telescopic structures could constitute a natural continuation of the Faraday cage that protects the occupants from the effects of lightning (the conditional is a must, as the appropriate checks are necessary).

FIG. 1 to 5 show the applications related to the “lifting system”; FIG. 6 to 19 refer to the “curtain system”; some components are common. All the elements designed are listed below in numerical order with the relative description so as not to repeat them later in the illustrations of the drawings:
(a) telescopic rod:
(a-1) telescopic rod structure made up of three elements of tubular galvanized steel (or similar) with a decreasing section from top to bottom, equipped with holes for mounting accessories and for telescopic adjustment of the length, variable based on the height of the vehicle to be served. To ensure greater rigidity of the rod, the length will be adjusted by at least two steel pins for each section of the rod, secured with quick-assembly UNI 3545 shaped cotter pins. The upper end of the rod will be rigidly fixed to the lock structure, as shown in detail “A” in fig.1, so as not to stress the same to tip bending, but to transmit the modest induced stress only to the fixing bolts of the structure. Let us see in detail the extent of this stress: suppose that the load to be lifted is 70 kg and the inclination of the rod is 300 with respect to the vertical. As a result of the decomposition of the forces we will have a force that will act along the axis of the rod structure with a compressive bending stress and another that will act on the upper support point, stressing the fixing bolts of the lock in shear.Il valore della Ia forza è il seguente: 70 x cos 300 = 70 x 0,866 = 60,62 kg = 606,2 N;
the value of the IIa force is the following: 70 x sin 300 = 70 x 0.50 = 35 Kg = 350 N.
If we consider that this stress is distributed over at least two bolts, we realize the inconsistency of the stress itself, considering that bolts with a minimum resistance class (3.6 of the UNI EN 20898 standard) have a nominal breaking load of 300 N/mm2; therefore a modest M5 threaded bolt with a resistant section of 14.2 mm2 has a minimum breaking load of 4690 N. Since this is not the place for the structural calculation of the rod, we only wanted to demonstrate that with the proposed solution it will not be possible in any way to cause damage to the structure of the car lock on which it is essential to lean.

The FIG. 1 to 5, are dedicated to the representation of the “lifting system”:
FIG. 1 shows a typical section of a car with the application of the load lifting and transfer equipment. The tool allows the aforementioned loads to be easily lifted, which generally do not exceed 60-70 kg, and facilitates their depositing and extraction from the passenger compartment with the help of a small winch with a crank handle (a-2). The telescopic rod (a-1) rests on the ground and hooks onto the structure of the tailgate lock by pushing the pin (a-6) upwards which releases the lock, the eccentric bracket (a-7) which blocks the lock to the rod is screwed on in order to avoid bending stresses on the rod, it is tied with a rope to the opening hinges of the tailgate itself, and below, to the wedges (c) placed under the rear wheels of the car; subsequently, the load transfer stand (b) is mounted, which is hooked on one side to the rod with the element (b-1), by means of a steel pin, while the opposite side rests on the internal floor of the vehicle by means of the telescopic feet (b-9 / b-10). The load is lifted by the hook (a-3) which passes through the two load-bearing plates (b-1). When the high position is reached, the load is stopped, the translation trolley (b-3) is brought close to the locking pin (b-4), it is hooked with the translation snap hook (b-5) to the rope and the support snap hook (b-6) to the load; the support rope is loosened by turning the winch crank in the opposite direction and making all the weight rest on the trolley (b-3), the suspended load is pushed inside the passenger compartment; Once you have reached the unloading point, lock the trolley with the pin (b-7), tighten the rope by slightly lifting the load with the winch, release the snap hook (b-6), place the load on the floor by operating the winch, finally release the snap hook (b-5) and the hook (a-3). To unload, carry out the above operations in reverse: hook the load (a-3), hook the rope with the snap hook (b-5), lift the load, loosen the rope with the winch (a-2), remove the pin (b-7), move the load outside the vehicle compartment, deposit the load on the ground with the winch. You can then dismantle the translation structure, transform it into a trolley and transport the load to its destination. Fitting the lifting structure to the vehicle takes no more than 2 minutes and the time can be reduced if the telescopic structures are already adjusted to the working height of your vehicle.
FIG. 2 shows the loading system seen from the top and rear of the vehicle with some slightly enlarged details. You can see: view “A” and the horizontal section with the positioning of the stand inside the passenger compartment and the locking system with the ropes (d) and (e); detail “A”, the hinge (b-11) between the arm (b-8) and the foot (b-9) and the position of the gravity pin (b-12); detail “B”, the hinge (b-13) between the arm (b-8) and the track b-2 and the position of the locking screw (b-14); detail “C”, the articulated plate (a-5) with the rope (d) connecting it to the wedges “c” placed under the wheels of the vehicle; detail “D”, the support plate b-10 of the foot b-9.
FIG. 3 shows an axonometric view of the telescopic rod with winch and accessories. You can see: the rod extended, in working position and shortened for storage or transport; the details (a-9, a-10, a-11), necessary for a further, possible use of the rod as a tripod.
FIG. 4 shows an axonometric view of the gantry structure for the translation of the load inside the passenger compartment. You can see: “A”, the articulated structure in the closed position for storage or transport (the open position is visible in fig. (1 and 2); “B”, the structure without the details (b-9 and b-10) to be transformed into a trolley; “C”, the structure transformed into a transport trolley, useful for moving luggage, household appliances, bags, work equipment, etc.
FIG. 5 shows the use of the telescopic rod equipped with a winch with the translation stand described above, coupled with two additional telescopic rods to form an easy-to-transport tripod with many possible uses (think of workers working in road manholes, lifting through attic trapdoors or simply handling equipment during assembly or painting phases in rooms without lifting equipment. You can see: the telescopic feet (b-9) longer than the version used for loading the vehicle; the cable connections “d” of the support plates (a-5); the enlarged detail of the upper connection with the particulars (a-9, a-10, a-11).
FIG. 6 to 19 are dedicated to the representation of the “curtain system”:
FIG. 6 shows three typical side views of the application of a curtain to the hood of cars:
a) low car without extension; b) low car with extension (a-13) to increase the curtain space; c) tall car without extension, which obtains the same result as solution “b” without the need for the extension, taking advantage of the greater height of the car and the greater length of the tailgate. Some considerations can be drawn from observing the drawing: that the system is enhanced by tall cars, with a long tailgate and penalized by low cars, for which the expansion of the habitable space is limited; for these, a solution has been provided that allows for its expansion, represented by position “b”; that the double wedge (c) has been provided in correspondence with the rear wheels of the car to increase the possibilities of tensioning the curtain without resorting to pegs; that the tensioning ropes (f-14) are grouped together to reduce assembly times; you can also note the following details: the position of the rainwater drain of the tent roof and the car roof; the position of the PVC pipe (f-12) to limit the flow of rainwater from the roof towards the tent; the overlapping of the terminal edges (f-9) with respect to the profile of the car; In the following drawings we will always refer to solutions with low cars as they are the most common, although as mentioned above the system is enhanced by tall cars.
FIG. 7 shows a plan and longitudinal section of a car with a “Canadian” type tent. You can see: the overlapping of the flap (f-11) on the open tailgate to limit the flow of rainwater to the roof of the tent; the extension of the sleeping area (f-8) obtained directly in the tent structure and directly connected to the pocket (f-3) for extending the support surface; the alignment of the internal support surface (h) with the external support surface (h-1); the shaped profile (f-6) and the rainwater drainage holes in the drip tray (f-7).
FIG. 8 shows a plan and longitudinal section of a low car with a “Canadian” type tent, complete with sleeping area inside the passenger compartment. You can see many details already highlighted in the previous figures and the details of the connection of the internal sheet (g) with the extension (f-8) by means of the detail (g-8); this connection is eliminated only for cleaning and washing the tent to reduce assembly times.
FIG. 9 shows two longitudinal sections of a car with a “house” type tent, complete with veranda and sleeping sheet inside the passenger compartment. You can see: a) the version with double external sheet that allows for comfortable sleeping even in the tent area, bringing the total number of beds to four; b) the version with a simple veranda and structure without an extension needs no comment. Both solutions require additional telescopic structures shown in fig. 14 compared to the “Canadian” versions.
FIG. 10 shows the plan view of the telescopic structures of the versions shown in fig. 9
FIG. 11 shows the horizontal sections of the versions shown in fig. 9. It can be seen that in the “four-seater” version the feet of the people sleeping in the tent area are subjected to the extension plane (h-1); this is possible without interference with the support feet of the table (h-2), which for this reason is equipped with a single central support, as visible in fig. 12 and detail fig. 19/a.
FIG. 12 shows the cross sections of fig. 9, it can be seen: in section A-A, the view of the access to the sleeping tent (g), the table (h-2) with the central support foot from the front side; the external telescopic structure (a-14) supporting the tent; in section D-D the view of the cottage tent subjected to the external sheet (f-15); the common detail of all versions, relating to the assembly of the tensioning rope (f-14) on the profile of the car with the PVC pipes (f-9) and (f-12), the tensioning of the base rope (d) by means of the detail (b-10) (used in a secondary function, being an integral part of the translation stand of fig. 1-2-5). FIG. 12 shows the cross sections of fig. 9, it can be seen: in section A-A, the view of the access to the sleeping tent (g), the table (h-2) with the central support foot from the front side; the external telescopic structure (a-14) supporting the tent; in section D-D the view of the cottage tent subjected to the external sheet (f-15); the common detail of all versions, relating to the assembly of the tensioning rope (f-14) on the profile of the car with the PVC pipes (f-9) and (f-12), the tensioning of the base rope (d) by means of the detail (b-10) (used in a secondary function, being an integral part of the translation stand of fig. 1-2-5).
FIG. 13 is the same as Fig. 3, the rod (a-1/a) is without the winch and the profile (a-4) connecting it to the translation stand, therefore the rod (a-1) could also be used for the “tent system”. As shown, it can be used to support tents in the Canadian version; for an extended version, it uses the extension (a-13); for the house versions it is integrated with other accessories shown in fig. 14.
FIG. 14 shows additional telescopic structures and accessories, necessary for completing the proposed system already described in the table: a-12-13-14-15-16-17.
Fig. 15 shows the axonometric views of the tents in the Canadian and simple house versions. The details already described in the table and in the previous detailed figures can be identified.
Fig. 16 shows the axonometric views of the tent house with veranda, and of the additional sheet with veranda, which can be superimposed on the simple house in fig. 15/b. The details already described in the table and in the previous detailed figures can be identified.
The sheet (b) with the telescopic structures of fig. 14 could be used without the underlying awning by street vendors who use the car to display their merchandise sheltered from the elements.
Fig. 17 shows the axonometric view of the sheet inside the car. You can see: the lateral openings with zippers to access the inside also from the rear side doors of the car, as well as from the bonnet; the zipper on the wall (g-1) communicating with the front seats of the car; the trunk (g-4) shaped according to the profile of the opening space of the bonnet; the lateral and lower fabric flanges for adherence to the body of the car (g-5-6); the hole (g-6/a) for the passage of the hook for mounting the extension (h-1), the hooks (g-7) for suspending the rear end to the upper drip; the fabric flanges with tear-off felt for connection to the sheet extension (f-8).
FIG. 18 shows the details of the extension (h-1) and the support surface inside the car: you can see: the interlocking composition, without the need for tools, between the components (h-4-5-6-7-8) which determine the support and containment surface also for the slats (h-3); the creation of a space for storing material in the gap created between the floor of the car and the wooden support surface; the trapezoidal shape of the surface (h-1) which follows the shape of the sheet (g).
FIG: 19 shows the auxiliary functions that the wooden components (h) can perform to reduce the quantity of transported equipment: The support (h-2), of the extension (h-1), as already anticipated in fig.9 -11, has been designed with three telescopic supports to allow the extension to overlap with any sleeping places in the tent compartment; the lower support surface, consisting of a table that, when placed on the waterproof sheet of the floor, does not cause damage; in detail (a) it can be noted that this inverted support becomes a small rectangular table; since the size of the table is equal to that of the three slats (h-3) it was planned to couple them together to form a wooden box, useful for containing most of the system components, in particular the telescopic structures, during the storage phase: detail (c) shows the box assembled by means of two head panels (h-9) and coupling hinges, mounted at the head of each board and on the four sides of the detail (h-9); Section “A-A” and view “A” show further details of the assembled case; the same slats (h-3) and details (h-9) can be used to make sturdy stools if coupled with folding trestles, as shown in detail (b).
Conclusions
Obviously, the tent system illustrated above only wants to demonstrate that sustainable development cannot be improvised but is designed globally in small steps by developing all the details that slowly find their place. The car tent illustrated above would have been very useful if a small company had invested in the modular construction of the accessories and built to measure for individual car models through an internet advertisement. These things cannot be done by the inventor who has the duty to develop other ideas and make them available to people who do not know how to design. For these reasons, inventors must be granted intellectual property, not industrial property. Industrial property must be granted to the manufacturer who purchases the national or international production rights. I don’t remember how long it took me to develop this project but I certainly worked on it for two or three months. Instead, I remember well that I spent 400 euros to file the patent because in 2007 there was no electronic filing which today would cost 50 euros. In 2007, the bureaucrats of the patent offices counted the number of pages filed and the number of claims. Their calculation required the payment of four hundred euros just for the production of the system in Italy which obviously, did not find interlocutors, like the other forty inventions of the undersigned, which did not even find interlocutors. When in 2016 I invented the autonomous energy generator that extracts clean energy from the environment and I mounted it on the same car that in 2007 I had used to pitch the tent, I closed the system opened in 2007 creating a sustainable mobile system that if it had worked, would have allowed us to survive even at the poles and in the deserts without fuels since the current heat pumps, already existing, do not need fossil energy to work but only electricity. But all the capitalist and communist world governments have continued to support the current car manufacturers with incentives and funding to continue using heat as an energy source by improving the quality of fuels and using purification devices such as catalytic converters, increasing the cost of transportation, without completely solving the problem of pollution and global warming.
All this would be ridiculous if I were right, because on planet Earth, energy is everywhere. I realized this by chance after having filed four international patents on the cleaning of fossil energy that no government and no multinational has financed, where I had planned artificial rain on calcareous materials to reduce CO2 and combustion oxides by producing carbonates in the water. To reduce the costs of this simple process I invented the submerged hydroelectric system that within the same basin, large or very small, by putting in series a pump that pumps in the direction of the gravitational force and immediately below it an identical pump connected to a current generator that works as a turbine, I realized that the current generator produces much more energy than that absorbed by the pump motor for the simple fact that the pump works in the gravitational direction and exploits the hydrostatic head and transfers the kinetic energy to the twin pump that works as a turbine, which, by turning the shaft of the electric current generator, simultaneously produces both the part of the energy due to the potential energy and the part of the energy due to the kinetic energy supplied by the pump motor. From this intuition was also born compressed hydroelectric energy and many other strategic and interactive inventions that would have simplified and shortened the purification and energy processes, which official science pretended not to understand in order to continue to heat the planet at the service of governments and multinationals. The simplest invention is precisely the energy-autonomous current generator that no country has financed. Which could protect even the poor and bombed people from the cold and heat, but we do not know for sure because the inventor of the compressed hydroelectric system was left alone, although he spent over 20,000 euros to pay for national and international patent deposits, in order to seek public and private interlocutors, respecting the laws that the United Nations have spread to regulate world development through the WIPO (World Intellectual Property Organization) which is precisely, a body of the United Nations. WIPO, instead of helping inventors, forces them to pay taxes that they should not pay, as writers, musicians, artists in general do not pay, who do not create any direct scientific, technological and economic development. This is the reason why inventors not linked to the centers of political and economic power on planet Earth do not exist. If they did, global warming would not have even started. Today it cannot be stopped for the same reason. In my article https://www.spawhe.eu/the-spawhe-rhyme-and-the-map-of-the-website/ I make a complete list of unfunded sustainable inventions that would have prevented and purified the wrong inventions that have produced global warming.
The figures below show the hydroelectric car that could enable sustainable tourism in the future, the power generator that could enable climate survival even in a tent by coupling it with a heat pump and a futuristic space container equipped for human survival without fuel and nuclear energy.
