Power station which generates electrical current out of natural resources such as wind, light and hot air

In the two patent applications submitted by me I should like, in accordance with my ideas, to move towards generating energy and also reusing it which is possible without substantial pollution of the environment and benefits human health. There is a demand for wind power, solar energy and muscle power. It is certain that no great energy output can be produced at specific points, but viewed as a whole great energy forces are liberated. On the basis of the discussion relating to environment-friendly electric cars, I thought of developing a means of transport which consumes minimum energy and has a low intrinsic weight. This vehicle can meet a certain demand, at least in the short-range sector, and at the same time help to reduce noise and air pollution. Thus, I believe that in the three-component drive I have found a possibility suitable for an environment-friendly means of transport. The more so, since many technological requirements already exist today: such as good magnetic materials, ...
