![]() I want to make a small wind turbine (about 2' OD) to put out in the backyard
as a wind speed indicator and something that might keep the birds away from my solar mount experiment.. I've been looking at these vertical spinners.. One hour projects Because they seem like the easiest to make. My question is, does the 4 blade have any real speed or torque advantage over over the 3 blade design? Just looking at the angles, is seems like the 3 blade would be less draggy and spin faster in less wind.. But, I haven't a clue if that's true.. Thanks, Rich |
