I think people love mini vertical axis turbines for their supposed simplicity and safety i.e. never spinning faster than the windspeed directed at them.
As we know, vertical axis turbines need to be BIG to be of any use, Torque being the best attribute at a low speed.
I want to create a small VAWT using an already made dual rotor axial flux alternator I have here.
Multiple outdoor LED lighting and/or a 3.6v NiMh battery pack charging is the goal.
A bit of Summer fun :D
