I was thinking of finding ways to make a steam boiler that any old Joe could make. Out of an old engine, an old hot water boiler they might find, etc. Things like that. The "steamer" could power a small turbine for electric or the steam could be used for sterilizing soil for hydroponics.

I believe you could use a water fired boilers to just move water in a in a circular pattern around a hydroelectric type water wheel. I would use 1.5 inch diameter galvanized steel pipe inside a large wood stove like a Riteway, or inside a barrel stove. But again, one must buy these materials up front. Replacement parts for a water boiler for just hot moving water would be fairly easy to come by in scrap from large complexes after a pole shift, I think.
