Wilesco D20 stream engine with M66 dynamo

This video shows my Wilesco D20 stationary steam engine.
It has been modified with a rerouted exhaust, ethanol burner. The M66 dynamo has been installed pulled by a 38mm pulley. The dynamo powers 4 white LEDs in a lantern.
I know there are more efficient ways to power 4 LEDs but this involves fire, smoke and oil so the fun-factor makes up for it.
With this video I tried to capture all the steps I take to run the engine and to clear the boiler from water afterwards.
Hopefully you enjoy my video. In case you want to know more about how this engine works look for 'double acting cylinder'.
