i could build a machine that does the same thing that only takes up the space of a zoom box. this is overdone.
MAN, I AM CONFUSED!!!!!! +1 for awesomeness!
the boiler explodes because he utilizes the bizzare element which solidifies at high temp and liqiufies at low temp
as soon as the fuel ran out the bizr at the top of the boiler vapourised and burned the whole plant... you might need to look at this...
Anyway, fsep it the best fuel in tpt, cause only it has so high temperature of fire ~ 10 000C. I made also many boilers on gas, oil, coal, etc, but all of them cant make steam temp more then 400-500C. I wanted to make really powerfull boiler, so I used fsep.
