Question

Nowadays,everyone are being trouble about the car's power which is one of the most improtant things for the human being!!

the oil can make the power and let the car move up, but does anyone knows the other natural power which can help the cars'

moving......the wind!!

everyone should knows the wind can be used to make the electricity, and when the car was moving and with the fast

speed---we can feel the winds from the front of the car......so why not we don't use this power form driving the car to

make the electricity to help the car??

Also the sunlight could be used too-----it can help us to save the power for the using when we don't get the oil to use

Anyway, I think the oil could be and just be the power which can help the people to use the electricity power more.

And also, I think if the car could be used by these 3 kinds power: wind, sunlight and the oil......our earth could be better

!!??.....

Answer 1

First, the wind.  Yes, you can feel the wind when you are moving fast.  But to make the wind do work making electricity, you would have to add extra drag to the car that would require more incremental power than you would gain.  Net loss.

Second, solar.  Yes, you could use solar cells on the top of a car to make electricity.  But in the "ground mobile" environment of a car, the cells would have to be very robust, or they would break often.  Even still, there is probably not enough area on the top of a car to make a big enough difference to offset the cost of the reconfiguration of the car and maintenance of the cells.  Yes, you could save some oil, but solar cells on the top of a car is certainly not the answer.
