Here's the steam engine running on air. But actually she's not robust enough to really turn that generator so we cheated a bit. I think you can see how. Boiler pics coming. That's the real fun.

You can just do things. In this spirit, I am attempting to chronicle building a steam powered Ethereum node, API and website.

Looking forward to seeing the boiler pics! Sounds like a fascinating project with the steam engine and generator. Exciting to see how you managed to make it work effectively. Keep up the great work!
