Why not just try to create a car that uses wind and solar energy and runs on electric?

You know, a car that has turbines on the wheels, solar panels on top, and some tiny windmill like objects to create energy while driving?

We should invent one that runs off a person's own sense of self-satisfaction.

One of these three ideas is bad. I wonder if Water, the soon to be engineer, can tell us which one it is?
 
Probably the turbines.. but I always wondered why no one else has thought of it. Probably because it's a bad idea...
 
Windmills have turbines in them right? As the windmill turns it makes energy by turning the turbine. Well, why not use the same idea and just use the wheels to turn a turbine. Like on a Front wheel drive, use the back wheels to turn a turbine that creates electric. Why would the windmills be a bad idea?
 
Perpetual Motion idea..........

It is feasable..placing alternators on all four wheels...just a matter of gearing so the output exceeds the useage(Batteries for startup)...down the pike and in R&D I would suspect...but probably will not be implemented until fossil fuel is gone...imho!
 
But the windmills would create a lot of resistance, wouldn't they? That would be tremendously counterproductive if the objective is to increase fuel efficiency, whatever the fuel.

How much solar-produced power would be required to run a vehicle? Can this be made self-sustaining even in cloudier areas such as Oregon and WA state?
 
HUH................?

Windmills are akin to generators/alternators...not at all realted to 'solar power' except they could both charge batteries!
 
Wheel turbines are a bad idea. The source of the energy that they collect is the motion of the vehicle. The motion of the vehicle is created by the motive force of the engine. The application that the Prius uses is to recapture kinetic energy into electrical. Again it has the same source, but in a normal braking situation would simply be dissipated to waste heat. Prius' braking system eliminated wasted energy, not created new energy.

Similarly, the apparent energy of the wind comes from the motion of the vehicle - original source is the motor. Entropy ensures an imperfect recapture of the energy, so it would be a net energy drain on the vehicle.

Solar panels do not have the ability to power a car, but use it is as a trickle charger for the battery, or even to partially recharge a drive battery while the car is parked, then it avoids / lessens the use of other energy forms.
 
I beg to disagree with...........

this hypothesis...it is just a matter of gearing...usage vs output...simple math/kinetics...we may not be there yet..or maybe we are...just not released as this would put a damper on the fuel industry!
 
It's actually a lot easier than high school. I'm bored out of my mind.

Would I have a challenge if I had gone to a real 4 year school straight off? I guess it doesn't really matter. All the universities in Mississippi, I think, are required to accept Community college transfers...
