Tested on the back of a car on a country road in New Zealand.

This is the second test of the super low cost ($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 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 and getting some usable power off the thing.
