Let's say I build an ethanol distiller, that burns ethanol to distill ethanol, which is in turn used to distill more ethanol. Is that overunity? Would I get more ethanol than it takes to distill the ethanol?
I think it's not overunity, because there is energy entering the loop from an external source. Ultimately, the sun, via photosynthesis, then fermentation, and finally ethanol. But, I'm not 100% sure.
