I don't know if this is the right place for this, but here goes anyway:
I've been reading about rocket mass heaters for years and now live in Molalla, just south of Portland, OR, but only for the next three weeks. Some day I'll take a workshop on it, but it'll be years before I'm back in the area and have a house.
But I want to keep the fire alive by actually getting to see someone's RMH in action. Someone want to show off yours to my wife and me before we move out of the rocket mass heater Promised Land?
