Vehicle Energy Production | |||||||||||||||||
Obviously we are all looking for energy storage and production. Well, why can't we produce a vehicle that's back tires produce energy while rolling. This would not be at the cost of the primary engine because it is already pulling the vehicle. So, the front tires will drive from force of the engine. As the back tires roll, they will turn a turbine in the vehicle which will produce more energy (electrical) which could power a battery or electric powered motor. If this would work, why is it not being used? If it is being used, why haven't I noticed it?

haseldee,
This is sort of like the question of 'if you can lift your own weight, can you stand on a platform with brackets and lift yourself by them to fly?' No, you can't. The energy input for generation has to come from outside the system, otherwise, all of the power you generate will have to be supplied from the power engine. You gain nothing, but lose to friction, etc.You've proposed another perpetural motion machine. They don't work.
i agree to hrench. but its a good effort and i like your thinking
good effort. I have a fix to your idea though.. put a clutch on your back tires connected to a generator so that it freewheels. then whenever you push your brakes the clutch engages so that you generate electricity by slowing down instead of heating up brake pads. You'd still have to have a braking system for quick stops but otherwise you wouldn't. Basically, this is what they have on hybrids already.
This must be the most popular optical illusion in all of history. It seems logical, but it cannot work.
