generation of electricity using motion of vehicles...

well yes we can do that and not motor but the generator (mechanical to electrical energy)

goog idea dude..i think we have to deploy a fly wheel into the concept

yup i ws just checking out whether this concept is applicable or not.... by the way what is this fly wheel concept....??

You certainly can, however it is much more efficient and higher generation is possible using a pto. This is why most engines have an alternator. Electric vehicles use generation systems via braking.

what is this pto...???

and what is the concept behind generation of electricity by applying breaks...??

pto stands for power take off, any device that uses the engine to supply power to operate, usually by belts and pulleys. A car alternator, AC system, power steering pump are all examples of pto. In trucks it can supply the compressed air to operate the braking system, hydraulics to operate a lft gat or dump bed, etc.

sanks85what is this pto...???

that means we have to provide a feedback system using PTO which can provide input to the system......??

Electric vehicles generate electricity when braking in order to maximize their battery life.

When braking, you're reducing the kinetic energy of the vehicle by converting it into something else. Regular brakes convert kinetic energy into heat. Regenerative brakes used on EVs convert some of it into electricity, which is then put back into the batteries. You are therefore getting some of the 'wasted' energy back, increasing your range.

EVs do this by (essentially) installing a motor/generator combination on each wheel, in addition to regular brakes. When you want to go, the winding changes electricity into motion; when you want to stop, the winding changes motion into electricity. It's a way of getting some 'free' energy - which is not free, because you generated it in the first place, but it would have otherwise been wasted.

EVs can do this because they have windings installed at each wheel anyway. Regular vehicles don't.

If you were to try something like this with a regular vehicle, you wouldn't get anything for free either. The gasoline motor converts gasoline into motion, which would then get changed to electricity at the wheel. Since the wheel speed is not constant, it would be difficult to generate electricity efficiently, not to mention the fact that you would get none when the vehicle is stopped. Using an alternator is a necessity, and since it's there anyway, there is no need to have complex generators installed on each axle.

According to me we alrady use it ,
in motor bike or any vehical a bettery is provided which is chage by the mosion of our bike. so it is one type of energy generation from motion and saving in 12 volt bettery

Yes it ofcourse could be like dynamo used in bicycles. It can reduce the use of batteries to a very high extent in automobiles.
