Damn. Didn't think semen would... survive? those temps. Don't think semen is technically alive since it can't reproduce. Or is that kinda the opposite since it is specifically made for reproducing? E: Just looked it up and sperm is technically alive but not an organism.
Solar has the problem of storage. You need something like a generator to tide those in-between times. Also you need the signal to be a clean 60 hz and solar apparently isn't very good at keeping the power clean.
