Crazy Powerful Steam Engine from Mokiitek youtub
I followed Mojiitek's tutorial titled "Building a Crazy Powerful Steam Engine in Stormworks" and created this steam turbine generator.
It takes a while to get to full power, though once up there it can produce up to 40K+ SWatts.
Huge thank you to Mojiitek, they have lots of good, concise tutorials I highly recommend looking!
