Saw this site on a Google search--lots of interesting stuff! www.theepicenter.com They show how to make a generator out of a lawnmower and a GM altenator,among other things!..They also sell MRE's,and inverters,and other survival related military surplus..
I looked up "homebuilt generators" and found a site that shows how to make an induction motor into a generator,simply by using capacitors,and a gas engine to spin it a bit higher rpm than its rated speed as a motor!..also a home built welder using a car altenator and a lawnmower motor--one was mounted on a riding mower!..
Another site sells plans for "Fuelless engines",and how to extract hydrogen from water to run engines and a heater that uses no electricity,by putting a zinc rod in used motor oil in an aluminum barrel!.--and how to make your own batteries from pvc pipe,and clorox bleach!--among other things!--.some interesting stuff!..

--even 12V power would be better than none..but a GM altenator with an inverter will power a furnace or refridgereator..
