Wind Turbines for an Electric Car

03/18/2009 10:15 AM

im a senior in high school. im taking an engineering class where we have to create anything that is needed, just as an engineer would. Our idea is to create a self sustained electric car. We have a few issues though and are looking for advice.

First, we have researched that by placing wind turbines in the front of the vehicle, that it will cause too much drag and cause the motor to work harder. We are not sure how this concept works. Also, we are curious about where the best place is to put wind turbines at on a vehicle, to produce as much power as we can. Lastly, we are also not too sure how much power a wind turbine creates, so if you could give us some advice, it would be very much appreciated.

No it happens all the time. With such a large group of people reading CR4 someone is bound to have come across something that is similar or relevant to the posts that others haven't heard of. There is very little that hasn't been tried before in some form or other (especially in the fields of automotive and power generation), which is why it is so important to perform an internet search before asking a question or embarking on an invention or patent (because chances are it has already been answered or done).

This is a scam.

I don't argue with those who believe in perpetual motion and ignore the laws of thermodynamics.

Use a combination of wind and solar to charge batterys . Use a 48hp dc motor to power the car.

Use 10 or 12 old 12 v batterys to give you some distance.

Dear takethislife85:

You have triggered many creative brains in CR4 and I hope you are happy with the outcome.

On thinking further, an arrangement which could provide some extraction of energy while reducing the energy requirement overall occured to me and I thought of sharing this with you.

Usually, we look on solutions on an "all" or "nothing" sort of attitude and so you find "jerky" responses. If we take a look on the problem with an "open" mind, some seemingly sub-optimal solutions do come about and which can be refined progressively towards optimality.

Now, if instead of one large wind turbine to extract energy, we consider a number of smaller ones, the sum total output will be much more.

Let us look at co-axial vertical turbines wherein the body having vertical fins is partly exposed to the "Slipstream" of the carbody and this revolves around the non-moving armature core, you'll have power generation......while at the same time you would have reduced the drag-co-efficient of the carbody, because the slipstream friction changes from surface sliding contact to rolling friction!!

I suggest putting a number of such small turnine generators all along the surface having exposure to the slipstream, on the sides, roof, wheel wells and even the bottom of the vehicle.

Yes, we have to look at the costs and aesthetics of course.Call for a drawing, if this idea does not sound too wild or weird.

Keep thinking and good luck with your efforts.

I personally think that what you could do instead of putting the wind turbine on the front of the car, you can have wind tunnels along the side and even the underside of the car, which would increase the pressure/speed of the air rushing into the tunnels, which would turn multiple turbines at higher speeds generating more energy.

So theoretically, what could happen is the car starts up with electric power, and then as it moves, the wind rushing thru the wind tunnel at high speed because of the design (shape and size of the wind tunnel) will create enough energy to power the car. :D

Hope this helps.

"Hope this helps."

Sorry, Guest. It doesn't help. Your suggestion is another variant of an impossible perpetual motion machine. No machine can deliver more energy than what is put into it. The basic law of physics is "Energy can not be created or destroyed".

hey everyone,

this is takethislife85. thanks so much for the posts. its been a long time sense iv thought about this highschool project. now im in the airforce and highschool is long behind me. im happy to see that people are still commenting on this thread. i think you have inspired me to continue with this idea, but more on a recreational aspect(think about it here and there and do what i can). mabey some time in the future il have drawlings and all the math for this.
