Let%26#039;s say we have an all electric car. Could we put a small fan in the front of that car, which would turn when the wind passed it as we were driving that car. Could we then hook the fan to a small generator that could assist in the car being recharged. Thus needing to be plugged into the electrical outlet for a shorter amount of time.
yes you physically could, however it will add to the air drag of the vehicle. Also nothing is 100% efficient at generating or carrying electricity, so you would lose power through the fan, generator, wiring, etc. Overall it is EXTREMELY likely you would actually be wasting more energy to push the fan blades through the air than you would gain from them. Which is why none of the electric cars ever mass produced have one.
It would not be very practical as you need lots of power to recharge an EV. That means the wind turbine would have to be pretty heavy and bulky. That would significantly slow down the car and mess up the cars aerodynamics. You can%26#039;t recharge an EV while its being used either. The setup and electronics do not allow for that. You%26#039;d be better off just having a conventional wind turbine at your house that charges it up.
In addition to what has already been said, air passing through the front of the car is used by the radiator to help cool the engine. I am guessing that a fan (or anything that would restrict the flow of air coming into the radiator) would have a negative impact on its operation.
I am not a mechanic, so I could be wrong on this. However, I believe my reasoning is sound.
You could do it but the energy you capture with the fan will be offset by the increased drag on the vehicle by putting the fan there.
Energy never comes free.
Go back to school!!! The fan will load the motor to pull it through the air.Quit trying to get something for nothing.Every time U Convert from mechanical to electrical U loose about 40%.
No.
