Why can't the the wheels turning on a car be used to charge a hybrid battery? - hybrid car principle
I know that braking is used to recharge a hybrid car charge, but why not the spinning wheels in the same way? Electricity produced by turbines in various types of restructuring, windmills, waterfalls, even a buried coal-power electricity is produced by spinning turbines. Cars no longer follows the same principle in a position to run almost without end?

Hybrid Car Principle Why Can't The The Wheels Turning On A Car Be Used To Charge A Hybrid Battery?

The generators are not perfect devices --- both electrical and mechanical sources of power loss, or rather a part of the energy is converted into heat by friction and resistance. In addition, the increased load on the engine with the current requirements of the engine, the so-called "IR losses squared increases to increase the engine over to battery power than without the generator. In essence, you add more resistance and heat with the environment --- without the generator and the heat is equal to the loss of power that could otherwise be used for further on the road.
Therefore, the brakes work so well if the generators in the wheels back to power batteries, which generates a load or resistance ... and the dynamics of private vehicles is the source of power. Since the time nor the energy absorbed and converted into electricity, the car is slowing down, what I did not start, so no big deal. If producerss running all the time and not only during braking, it would be like driving your car with the e-brake all the time around ... Which would put more load on the engine and actually be less effective.
You can not make electricity with electricity and offset the energy lost ineffencies into mechanical devices, and generate the energy needed to power the vehicle. Must be met in other ways.
Well, if the wheels turn, you want all the electricity / gas from the wheel for maximum efficiency of the work produced. So you can turn a generator when the wheels are in motion, but it takes much more energy to produce energy, so that it would work agaist him. But when slowing or stopping, would be more effective. The generator (alternator) in the motor is large enough to provide sufficient support and energy to keep the car running and all the accessories, but under conditions of high-revving, cut to provide maximum performance engine.
They do. An engine that is connected to the wheel and drive wheel. If you want to stop the power from the wheel and the motor becomes a generator and feeds the energy into the battery.
How it works.
If you take away energy turning the wheel, it means that the wheel is turning slower and is, consequently, the slower car. And guess what? What is regenerative braking.
