This is the second test of the super low cost (NZ$30), 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 a gusty tail wind which kind of messed up the data. I'm pretty happy with 105 km, and the next step is attaching a car alternator with a rope belt and getting some usable power off the thing.
