i believe that a combination of wind and solar is the best , you can make one with the car alternator, but i dont think you can get you best output that way, i have seen ceiling fans used as well as just box fans , again not much out put.
you can make your own which seems to be the best.make yourown
then you can run this through a diode and change to dc, then to a battery and then to an online dc to ac inverter.Grid tie inverter
the only problem i see with this set up is if the grid goes down for what ever reason, you have to do something with the power being made. I am sure you can see this being a problem during a bad storm, while this will be putting out some serious power.
although you can short out the three phases and that will work as a brake, but will not stop the wind mill from spinning.
hope this helps some
I like the VAWT the best.
