Regarding my wind turbine, what to say. I’am DIY man and it is my hobby. I have weekend house in the mountains approx. 650 meters above sea level and sometimes its pretty windy here. Inspired by Otherpower.com many years ago I told myself why not to build small wind turbine. I bought from you plans sometimes around 2005.
My wind turbine is clone of your’s design: 2.8m diameter, coils modified to start at little bit lower rpm, pole is approx. 18 m high, system is 24V, charging batteries and using produced electricity via inverter. Later on I added PV panels to cover consumption during non windy days. During those approx. 11 years I’am running it I had once problem when during the storm tail felt out and interfere with the blades and now I’am doing some service as the hub bearing became noisy.
Some pictures (btw I like North, moose and reindeer 🙂 )
