Homemade Wind Turbine Generator! Wind Power Generator. Easy DIY Instructions. items needed: PVC Pipe, propeller blade, DC motor and wire. Stand is made of 3/4″ PVC. Produces essentially “free” usable power to run radios and small lights etc… add the optional battery/inverter for making AC power. adding a storage battery also makes it possible to run larger items (whether the wind is blowing or not) …and add a small inverter to run AC powered items. this “table top” size model would be useful in many off-grid situations including SHTF/Emergency/Power Outage/Camping/Rural Living etc… simple assembly/disassembly. durable, lightweight and portable. notes: propeller blades of this kind can be found at your local hobby store. use PVC Pipe Cement to make the stand more “permanent”. the wire i used is from an old extension cord. since filming i’ve reduced the length of the wire from 8 ft. down to 2 ft. (shortening the wire increases power output). low power radio was used. operates on as little as 28-35ma at 2v-3v. (43ma at 2.4v was average output using small desk fan). volt/amp readings on meter were all over the place when i used the leaf blower (5 to 10 times higher vs. desk fan). leaf blower produces wind up to 140MPH. i blasted the wind turbine with blower from about 3 feet away for over 5 mins and it stood firm entire time.
