Own design high tsr twin blade rotor fitted to a futurenergy pma/pmg in a mild North wind. I can preset theangles on these rotors to match & be efficient with many pma's. Delco types,
Those can be made quite good, but hard to get enough chord(blade width) for good surface area i think, unless you use 5-6 of them, and then they get complex.
runs faster than my pvc drain pipe blades.lol
