How to build your own wind powered car??

Question

I saw on youtube.com about those guys that made a car that runs on mini wind generators. The generators charge the batteries making it an unlimited source of power. I want to know has anyone come across a site that helps people like us build there own car like that?? I would appreciate it if you could respond back with some people that know how to do it and are willing to help others. I just need some ground plans.

Answer 1

It won't work. The power to move the car and the wind turbine would more than equal any power the turbine generated.

Perpetual motion machines do not work, never have worked, never can work. You can't get something for nothing.

YouTube is full of fakes.

Answer 2

I think that if that car was a reality, then the plans would be hidden somewhere so that they could be sold off for a great amount of money.

I cant see how it would be a viable solution. The wind driven turbines would need to be very large, and you would also need a battery or storage capacitor of some kind for when there was no wind.

It would be very expensive to build, and in my opinion, very heavy.

Answer 3

First, you will want to understand the laws of thermodynamics.

There is an inherent loss when converting mechanical (wind) energy into electrical energy.  There is a further loss (in the form of heat energy) when that energy is stored into batteries, due to the inherent resistance presented by a battery not at full charge.  Then there is yet another loss when you convert that stored electrical energy back into mechanical energy.  What this means is that you will never get back what you put in to the system.

Each "Fan blade" and "Generator" installed on the car adds GREATLY to the wind resistance the car must overcome.  This requires more energy.  The energy required by the car to overcome the wind resistance at any reasonable highway speed is going to be considerably greater than what these generators can generate, even if you don't account for the laws of thermodynamics.

At the end of the day, a much better solution to harness the power of the wind for automobile use is to erect a stationary, land-based electric generator windmill which can be used to recharge the batteries in your car.  It would need to be built where it's usually windy, and might supply enough power for short trips if it's windy enough overnight.  That way, the energy you store in the battery won't be wasted in overcoming the wind resistance of the generator.
