Rigged this up a few days ago. 12 volts depending on how it feels. First stab at feeding it into an inverter to see if I could light it at all. No success given that it behaves a bit differently from usual batteries.
I'm likely going to say fuck it and convert these into charcoal cells, since I rigged one up a few weeks ago and its output is pretty phenomenal for the size of materials. The charcoal will eat both of my electrodes, but being that this is a test and that I need to move my ass on this before winter hits again, I won't get anywhere if I don't try things and take some losses.
Generator project hit a snag. The magnets I got for it work fine, but I'll need hundreds of them to line the wheel, which amounts to thousands of dollars I don't have. So I'll have to downscale things to work with what I've got.
