Open Source Wind Turbine 100 km/h Survival Test

Construction tutorial at: http://solarflower.org/tutorial.php?lang=entut=vawt This is the second test of the super low cost ($20), easy to construct (6 hours for two people) build of the Lenz2 vertical axis design, with the intention being of surviving sustained 100 km/h winds. I didn't log and graph the RPMs on this run as I did in the last, as we had an intermittent tail wind which kind of messed up the data. I'm pretty happy with 105 km, the next step is attaching a car alternator or pump with a chain
