Hi
I was reading your posting about VAWM. I worked quite a bit on these and sebosfato is correct it would be too much drag . However...
I did run soem tests on putting a VAWM in place of the radiator and venting the air under the car. I found no extra drag on the car and was able to produce a constant 12 volts with upto 10 amps. Unfortunately it wasnt enough to run a car motor.

I see, yes the drag would be a lot cause this vertical axis are very efficient, if you don't vent your radiator you must keep attention on the engine temperature... normally in the road the radiator don't even work cause it is refrigerated only by the air coming in.. so there is a thermostatic valve that shut off the water flux thru the radiator... keep going =)

What you mean by vawm? How did you measured the drag?
120watts of drag is very small compared to tens of kwatts of the engine power...
what do you think?
Hi Sebosfato
VAWM is vertical axis windmill. The ones that I made used vents to funnel the wind into the vanes and spin the aletrnator shaft.
I measured the drag by speed . I also used a roof mounted unit to see what if any drag would be there. I dont recall exactly how much speed I lost but i do recall it was significant.

I'm not an expert in turbines but i can help you understand better if you ask me some questions.
You want to put a turbine over the car to use the wind to generate the electricity to charge the battery of the car witch is electric?
If this is the case it won't work and i explain you why.
The turbine will create a drag (resistance) to the movement of the car and wont have higher efficiency than 100% so you will just lost energy doing so.
Regards
make me know if this was what you intended. ..
bye

I have been thinking lately of implying a vertical based blade turbine on the top of the vehicle, being a expert on turbines, could you tell me what might be the chances of getting this kinetic energy back to electric energy? I am trying to charge my electric batteries for the electric car. Please let me know your concerns about this?
