power readings from the 2 lenz counter rotating turbines . N E wind at 12 mph on roof annemometer, wind is stronger out on the dock. This video shows the turbines some of the other videos just show the gauges. The other video's are from a different day with stronger (22 mph) winds. The turbines are now mounted where I'm going to leave them over winter. The one on the dock I had been moving around on the the yard to different locations to try and get better exposure to shifting winds.
like this design! compact and probably produces a lot of torque for gearing.

Doesn't really have a lot of torque. It needs to be taller . The alternator a I made for it should have had more turns of wire. usually needs about a 15 mph wind to start charging. We are about to get our first winter blizzard here in Wisconsin today. possible high winds so I am anxious to see what it will do. Put this up last spring and it's been mildest summer wind wise I can remember.

I really like your idea of counter rotation, it doubled the rpm and more rpm means more amps produced. :-) Great job man! 5 Stars.

Thanks, It seems to help a little to cut vibration also.
