selfcontained electric car? Answered
I had a few ideas on how to make more efficient cars. First off why is it we have NO generators being used while stuffs rotating. Take a small generator with a rubber drive point...like there a chain or belt would go... and place that on the tires. This is a friction driven generator which means that it would not work well in the rain. These...if done right... could keep the car running and then keep the battery charged. Using the battery only for stops.
I also think we need to figure out a way to put a coil in the drive train somewhere. Making it to where when the car stops the coil is wound tight, when the car takes off again the coil could unwind and help the car take off. this feature added to gasoline engines would help cut the cost of gas greatly, not to mention emissions.
