India's air powered motorbike

A group of Indian engineering students has invented a unique pollution free bike which runs on air pressure and does not emit carbon in the atmosphere. Reuters Andrew Potter reports.

If we run our vehicles on air the government will tax it so much we won't be able to afford to breath.

how could it be putting out "nothing but Oxygen" if it's using compressed air which is 80% Nitrogen?

[fizzguts]

The running cost or air powered tools is CHEAPER that electric. Only on planet stupid where you live.

[Divad TLUANESRA]

yes but you probably compress you air with some kind of motor...

If I am a puppet, I am an educated one. To fools, education (even technical) looks like indoctrination. I am not trying to debate the use of fossile fuels, this is off topic. Do you have ADHD my friend?

[EngineeringFun]

This again is studied in school, in the physics class. You can educate yourself about the theory of thermal engines by reading your little brother's physics book. I post this for people to read not for you my friend. You are just spreading ignorance. I am not against new forms of energy. I am against using conventional energy and wasting it by turning it into an intermediate step, and doing this wasting a large percentage of it.

[EngineeringFun]

No, that's not true. The electric tools use the energy straight from the grid with an efficiency of 95% or more. The compressor however air needs an electric motor to compress the air which has similar efficiency to an electric tool. During the compression the tank gets hot (adiabatic compression) and cools down to ambient temp. You loose heat once. Then when you use the tank due to adiabatic expansion the tank gets cold which reduces the temperature/pressure. Here's a second energy loss stage.

Do you knwo they Burn crude oil to make fuel. This is proof of how you "engineers" have been brainwashed. LOL. You are like puppets who only are programmed to attack any alternative fuel with this psuedo theories.

While u never even acknowledge the obvious about fossile fuels. Just the amount of energy it takes to extract it from the sea bed or oil fields and then transport is Ridiculously out of proportion. This is one of the reason why fuel is so costly.

add 2 that peak oil & pollution
