I have been thinking for a some time now about the new electric/hybrid cars that have been coming out. In my opinion they are a really cool invention to have but it just doesn’t meet the peoples’ needs. As we know by now the electric cars need to be charged every (x) amount of miles. So I was thinking about how we can create a fully electric vehicle that at the same time doesn’t need charging. Then I thought about wind! We have windmills that create our electricity for us. So I thought of how a windmill might be installed onto the roof a car. Obviously the windmills would not be as big as the ones you usually see outside, but rather small and compatable. This would work great because as, for example, you drive an electric powered and wind powered car the windmill will start to spin which creates its electricity then the energy would be transferred into usable energy within the battery. By doing so, we would not need to charge the vehicle because the windmill would be constantly spinning, creating our energy as the vehicle moves. This would be a big step forward in energy technology because of how efficiently the car would work.

Oh but what about the drag coefficient?

In effect you will have to use the electricity you have stored in the cars batteries to drive the windmill / turbine. This adds to the drag of the car and so means you are in a loss cycle.
Rather than extend the cars range you will make the car less useful, than if you were just to charfe it and drive. A better solution is to incorporate PV cells on all exterior surfaces and let the car charge all the time , wheather it is stopped in a car park or while traveling down a highway. There is no loss due to drag as the shape of the car will not change , and by using light weight composits it should be possable to offset the additional weight of the solar cells. There is no reason why a wind gen could not be used when the car is stopped and there is wind available. But not when the car is traveling that would be perpetual motion and it does not exist in the real world.

I was reading on your site of an idea that posted as a top idea. The idea that a windmill on top of your car would be more efficient? Well the first problem is that there would need to be some type of consistent wind, which a car is not always moving. and what? put a 200ft wind mill on my car and wait until it charges…
the concept of wind i think is a good one tho just in a different since.. in reference to something called a MARS turbine, i would say on the side skirts and in the front, and possibly on the top of the trunk where the spoiler might go, small turbines acting as an alternator for the battery. while on highway or simply moving, would force the fans to spin thus creating the energy. if it seems like im 21 and not a scientist, well …
and for the considerate person who took the time to read my pointless proposal considering the amount of money funding energy advancement, if my idea has not already been proven wrong and or in the making… i would be considerably concerned. with that said, a gift…
