Savonius VAWT 2 stage oil drum wind turbine.

My two stage Savonius oil drum VAWT fitted with LG Direct drive/smartdrive 3 phase 36 pole generator. Producing about 12v 1amp in this first test! :) Goto http://www.thebackshed.com/Windmill/FORUM1/forum_posts.asp?TID=889&PN=1 for full details.

If you cut a rectangular strip out of the face of each half of each oil drum, and replace that with a hinged rubber sealed flap that is closed by the wind pushing it the drum around but opened when that face pushes against the wind, you might increase its efficiency as the side fighting the wind will now have a big hole through which the antagonistic wind can pass, and its closed when being pushed around. What do you think, I hope I've explained that clearly...

Really sharp job done on this Savonius. Used a Savonius on by wind powered tumble clothes dryer, the "Close Whirly". Trouble was, for a whole month after I built it , no wind! Had to use to use a leaf blower to spin it for my youtube vid.

Check it out, ... it's a hoot.

Most hortizontal axis designs will be more efficient than the vertical axis designs, but there are exceptions when considering designs and wind speeds. As a rule of thumb, most HAWT's will produce more electricity than most VAWT's, under optimal conditions.

Hi, most interesting. A local farmer had suggested this system when I was asking him for parts to create a wind-powered electricity generator. How are things progressing? I rather imagined this to be more effieicient than simple plane/fan type prop blades. Where can I get detail on the alternator/genny whatever?

PS am thinking of using smaller barrels due to restrictions. Well done anyway - good to know we can succeed despite academic assertions.

you could use it to charge batteries. Could produce about 100 watts in a strong wind. Enough to power a light bulb.

a 20W light bulb.

i dont know much or really anything but what can this power in a day ? eg apliances etc

[embeddedprogrammer]

This is very nice work. Did you get the LG used (salvage) out of a washing machine? I am doing something similar and am looking for a low-cost generator. I would like to see how you built this (bearings, connection to the generator, etc.)
