If you haven’t seen them, Jay Leno has several steam videos, they are excellent. His staff have become experts on the technology with the effort they took getting them running.
One of my favorites is his Advance steam tractor. Pity he keeps it in the city instead of having it in the fields where they can really show what they are capable of.
The Dobles are fascinating because since their steam generators heat up a half gallon of water at a time, there’s no danger of a boiler explosion in spite of the high heat thanks to the smaller volumes of steam.
