    • PURPOSE:To provide a car body in which a light receiving condition and a running condition are most rationalized by forming an electric automobile (a solar car) run through conversion of solar beams into electric energy so that worsening of environment, such as the generation of exhaust gas, noise, vibration, occurring during running of a conventional automobile is prevented from occurring. CONSTITUTION:Wing section type base sheets 3, 3', 3'', and 3''' are arranged vertically in two stages to a drum body part 2 of a car body and a solar battery panel film 1 is attached on the upper surface thereof to form wing section solar panels 4, 4', 4'', and 4'''. The upper stage wing section type solar panels 4 and 4' are coupled to the face parts on both sides of the drum body part 2 by means of pins and through vertical rotation operation, running in a posture optimum to receipt of light and running is practicable. The rear edge part of the wing section type solar panel are formed so as to operate as flaps 5, 5', 5'', and 5'''. During running, an air lift similar to that of an aircraft is generated and the weight of a car body is positively reduced.

    • PURPOSE:To remarkably enhance the safety of a passenger and to make the car body light in weight by inserting a metallic tube into a hollow part of a buffer tube, forming it like a cylindrical coil spring, providing necessary parts of an electric automobile in a cylindrical in-car space, and containing the passenger in its composite cylindrical coil spring-like car body. CONSTITUTION:A composite tube is formed by inserting a metallic tube (a stedl tube, an aluminum tube, etc.) into a hollow part of a buffer tube (a rubber tubes a plastic tube, etc.), and by forming it like a cylindrical coil spring, a composite cylindrical coil spring-like car body 3 is formed, and by coupling a floor plate 4 to its bottom part, a cylindrical in-car space 5 is formed. In this cylindrical in-car space 5, equipment parts (front and rear wheels 6, 6', batteries 7, 7', a motor 8, a seat 9, a driving handle 10, etc.) required as an electric automobile are provided, and also, it is used as a boarding space of a passenger 11. In such a state, while preventing local damage of an impact contact part by the buffer tube 1, an impact is softened by transferring widely impact force to the metallic tube 2. A cylindrical coil spring form softens the impact force in each direction, and safety of the passenger 11 is enhanced.

    • PURPOSE:To improve heat accumulating efficiency of a solar water heater by using as the heat collecting pipe in the heat collecting unit a flexible monolithically continuous compound pipe and forming it into a spiral shape, and to facilitate cleaning of said compound pipe by enabling it to be extended into a straight pipe shape when the heat medium passage is cleaned. CONSTITUTION:To outer pipe 1 and the inner pipe 2 are made of a soft plastic having sufficient flexibility, such as soft vinyl chloride or soft polypropylene, and concentrically disposed at a proper interval. In the space between both pipes 1 and 2, salt water having a proper concentration (e.g., 20-40%) is sealed, and a heat medium 4 is made to circulate in the inner pipe 2. The compound heat collecting pipe thus constituted is formed into a spiral shape and mounted on a support plate 5, and in its central portion a hot-water storage tank 6 is arranged. Then, the heat medium 4 is allowed to circulate between the inner pipe 2 of the compound heat collecting pipe and the tank 6 by providing an inlet port 7 and an outlet port 8 in the tank 6 and connecting the outlet port 8 to an inlet port 9 on the side of the inner pipe 2.
