Is it possible to use the fan in a laptop or computer to produce kinetic energy that will produce extra energy for power Answered
its not like powering a windturbine with lots of desk fans because obviously thats pointless but we need the fan in the computer and we could also use the thermal energy that usually escapes the computer as extra energy. what do you think? im guessing this is gonna have a simple answer why not because someonme should have allready thought of this, a car powered by kinetic energy from the wheels and or wind power outside the car. the ultimate green peace kinda car should be powered by wind rotation, wheel rotation, solar power on the bonnet or roof. iv heard some electric cars do use the motor spin to produce extra energy, when i said the spin of the wheels i also ment the spin of the motor, would using the wheels produce more power than juist the motor, thanks for any help instructables-ers ?
