Air-Powered Car

Air cars are powered by engines, fueled by compressed air, which is stored in a tank under high pressure such as 30 MPa (4500 psi or 300 bar),following ISO 11439 [1]. The storage tank is likely to be made of carbon-fiber in order to reduce its weight while achieving the necessary strength. Instead of mixing fuel with air and burning it to drive pistons with hot expanding gases; air cars use the expansion of compressed air to drive their pistons. This is so cool for the following reasons, first its environment friendly since it has zero emission, second we will say goodbye to the high gas prices, and third its very very economical. What can you say about this?

Who ever came up with this are not taking everything into consideration. Compressing the air will use a lot of energy, probably electricity and there is still pollution with generating the electricity to compress this air. It takes X amount of energy to move X amount of weight from point A to point B no matter how you do it. Air motors are known to waste a lot of energy. With the cost to compress the air it will not be economical. It would be cheaper to just run a battery powered car and recharge the batteries from the grid. Then if you could recharge the battery bank with solar you would really be ahead of the game. You can't help but give people like this an "E" for effort though because they are trying at least.

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.

Hello Tata motors is introducing it very soon in iddia, we are waiting for it eagerly, i just dont know how far it will be sucessful in our enviornment, our place is hot too.. Thanks for sharing. Welcome always. Cheers. Professor

Yeah I guess this is an interesting technology to develop in the coming days. I am pretty sure that these things would make things positive for the environment. Althoug according to what I read this technology may still use a little of gasoline since they are developing a hybrid type. But this will be okay I think if they would go for it.
