Air-Powered Car

Solar is the only way to go if you want to save money and cut down on pollution. Even then you must figure in the pollution generated in the manufacturing of the solar panels, The trucks to transport them to you and the same with the battery pack to store the energy. Man cannot live on this earth without generating at least some pollution. I agree we are producing a lot more pollution per person than we need to.

What you said is true. I haven't get to put into consideration the energy consumption in the possible pros I have. Thanks for sharing your knowledge. I have learn again this day.

I have toyed with the idea of re-designing a combustion engine to operate on compressed air. You can replace the cam gear with one the same size as the one on the crank shaft and it converts the four stroke to a two stroke. That way every time the piston goes down it is under power. This would eliminate the compression stroke and save a lot of energy. The fuel could be exploded in a chamber to produce the compressed air. Gasoline could be atomized with heat before it was exploded and this would extract a lot more energy from the fuel. Also you could use Hydrogen or propane as your fuel. I hope one day to set up a four stroke V8 and try it. You have to remove every other piston and run it as a 4 cylinder but you still get the full 8 power strokes in the two complete revolutions. You could even power one of these with wood gas or steam.My choice of fuels would probably be Hydrogen or propane. These would produce a lot less pollution and still give you good energy.
