I am an amateur wind energy enthusiast and is now working on a new wind turbine design of mine. I have made a working prototype and also tested it. I have measured the RPM of the turbine (without any load) by putting it before a table fan generating 6 m/s wind velocity. The diameter of the turbine is 25 cm. The RPM has been found to be 570 that is pretty high for such small scale turbine despite the friction of the two bearings attached to it.
But, being an individual enthusiast, it’s very hard for me to further develop this technology as per my desire. I want to know whether anyone here can help to develop it further? Waiting for suggestions. And those want to know in detail, kindly inbox me for photos and videos of the testing.
