Whoo hoo.. another new guy. I feel welcome, hope you do too.
Steam engines, well.. a guy in Florida runs them with solar power. Search him on youtube under greenpowerscience Dan Rojas .
I wanna learn how to build one too. From what I read, nobody has developed any advancements since the 1900s..
INSTANT steam, strong hydrogen peroxide shot through a SILVER catalyst screen makes instant steam.. but has silver screen "trash" in it. It is that simple, a instant steam rocket with a nozzle, or in a boiler instant steam. A boiler could be the size of a lunch box.
Let's play and have some fun here.
