A hydrogren factory I recently made. Makes use of a very efficient water distiller that uses boyl and sponge to remove the salt. (saving me from melting it away)

It then uses electrolosis to convert the distilled water to hydrogen and oxygen.

In powder toy, only iron creates electrolysis with water.  (so i had no choice)

They won't corrode in tpt as I'm using distilled water not regular.

But yes, in real life I wouldn't use iron.
