"The current interpretation by those who advocate that the feature on the rock is a human figure is that it commemorates a fallen member of the party of Henry Sinclair, a Scottish Earl whom some believe to have made a voyage to the New World in 1398, " This is the earliest solid evidence of Europeans in North America:

"Food remains included butternuts, which are significant because they do not grow naturally north of New Brunswick, " Or maybe they once grew further north in the warmer climate?

When I was in the Army in Germany I was the designated stuckee for get-to-know-the-locals jaunts. One was a tour of the local sewage treatment plant. After the guide had led us through the flower-bordered, unfenced, settling ponds she opened the door to a huge Diesel engine that ran on methane from a sludge digester dome beside it. It powered the facility and passed the excess power to the city. IIRC she said they had never needed to change the oil in it.
Read the first comment by SteamRoss.53. He has it right, except for the uniflow steam engines running on superheated steam. The whole point of uniflows is to avoid the need for superheated steam. You can do it, but it has nothing to do with the uniflow's operation or performance.
Other than that minor nitpick, the guy knows what he's talking about.
A hyped-up flash-boiler feeding a radial engine. They've been around for over 100 years.
Note that the feature pushed for the "Cyclone" is fuel flexibility. That's what drove the Stirling developments in the 1970s, including Ford's fleet of Stirling-powered postal trucks.
What happened is that we since learned how to burn just about any liquid or gaseous fuel in IC engines, and they have many advantages.
It's a very subtle skill that begs for hands-on instruction. If I wanted to really get into it, that's what I'd do.
Oh, I'm sure.
My interest in the subject goes back to the early '60s, when I received a copy of _Sports Car Bodywork_ for Christmas. I always wanted to try it but not to build a car body. I just wanted to know something about doing it.
So, not many years ago I was offered some 3003 aluminum, and I thought I'd give it a try.
If you get good at it, let us know how difficult it is, or not. It looks to me like the real experts can do it with amazing speed, even without an English wheel or power planisher.
