February 29, 201610 yr Cannot vouch for this at all. Looks Heath - Robinson but members may be willing to give it a bash. I cannot use all the power from my panels so I am not looking for extra projects. The extra power at night would be a bonus though. http://www.offgridquest.com/diy/diy-home-made-wind-power-generator

Also, that pathetic little fan is never going to turn it fast enough to make anything meaningful :-) A quick google suggests that alternator/engine pulley ratio is between 2 and 3, so if the engine idles at say 700RPM, that means you need 1400rpm to 2100rpm to make meaningful power. Soooo... you're talking a windmill wheel with a 15:1 pulley ratio, if my memory of the average speed of a windmill wheel in light wind is anything to go by.
February 29, 201610 yr You could buy the magnetic rotor and the 36-pole stator of a LG Direct drive washing machine and make your own machine by adding support and a shaft. The blades can be made of plastic cutting out the profiles from blue pvc pipe, or you could make the blades from other materials. http://www.thebackshed.com/forum/forum_posts.asp?TID=7025&KW=36+pole+lg http://www.thebackshed.com/windmill/Kits.asp
March 4, 20179 yr http://www.fieldlines.com/index.php/topic,149124.0.html Excellent project this... won't be climbing that myself though!!
March 4, 20179 yr Author Utterly amazing contraption. Sad that the practical experience will die with the old man. I remember watching my dad shoe horses and being fascinated as a child. It is not a skill I ever learnt since shortly thereafter we stopped using horses for stockwork.
September 12, 20196 yr Great insight into the build just subscribed and it’s a nice compact turbine I also have built a homemade 650 watts wind turbine, a treadmill motor turbine and a little but powerful ametek 30v turbine and built 2 diy solar panels, be careful in high winds one of my first turbines blew up 😕and now have only 2 wonderful turbines working daily 😊it’s very satisfying watching those things working, keep up the good work buddy 👍 Show less
September 13, 20196 yr my channel with all my crazy wind turbines are at https://studio.youtube.com/channel/UCcBS6Mgm3AAjYp0z596IL8w i am hoping to build a 7 to 10 kw home made wind turbine, but may need further advice from you guys on the electrics front hope you enjoy it
