This is so cool. I hope they are burning coal to produce the steam to go full steampunk.
Someone should do a water wheel powered one next.
That's a commercial off-the-shelf hobbyist steam engine, they prescribe using smokeless fuel tablets like [0].
Coal would just make a bunch of soot and a big mess in general.
