better make a electric heater 1+
@milan1031 well, a real steam engine works by the piston cam turning another cam along a shaft and that other cam pushes the valve door back and forth and opens the valve once at a time on on or the other sides. so pressure exerted from steam pushes the piston forward, triggering the opposite door to open, thus pushes the piston the other way (:
you could use pressure detectors and a normal piston
Good work i approve of dis.
nice, really nice keep up the good work man!
