Shadow&Flame posted this in the thread about the guy who was apparently running a generator in his apartment: This was posted in the thread about "Getting talked down to about wood heat": http://www.claverton-energy.com/mini-steam-power-plant-of-10-kw-with-18-hp-steam-engine-3kw-steam-power-plant-with-8-hp-steam-engine-to-run-on-renewable-energy.html Funny how Hearth members think alike It definitely has my wheels turning I'll say that much. The difficulty with these things is the unevenness of the power so I wonder if it would be best paired with a heavy duty generator head, an inverter, and a good sized battery bank. Kind of the same principle as boiler storage. You run the steam engine for however many hours a day to fill up the batteries, let the batteries discharge over time, and then run the steam engine again when you need to recharge them. Obviously the larger the battery bank, the less time between chargeups. The steam engine could feed power directly when large loads need to be run like a well pump, etc... I wonder how much maintenance they need? I know that the Indian made Listeroids will run for years and years without so much as a tune up. Steam engines seem like more finicky beasts though.
