Absolutely off topic, so in hanger flying, but I’m looking for a power steam boiler to feed an old prototype 5hp double acting twin cylinder steam engine I’ve got stashed away that I’d like to put into service on a mini “riverboat” style water camper. I figure there is a nonzero chance that some of the people on this site might also be interested in steam, so what’s the harm of asking? Preferably a solid fueled vertical fire tube, but flexible on that.
