Fuck it, it is completely pointless, there's nothing out there that doesn't require massive amounts of work and or expense. By the time you fuck around and manage to save any money, you could have made more working at some grocery store.
The only one that is still somewhat interesting would be to find a diesel generator and feed it biodiesel. The natural gas generator was interesting, as well, but the upfront cost is ridiculous.
I don't like to be cold or turn everything off all of the time, so fuck the rest of it
PS: Mr. Brass, did it cost you a lot to build your panels? Can you use them without $99999 worth of upconverters or whatever the fuck?
