I saw they have models up to 10 HP -- that's HUGE for a steam engine!! Probably 1500 ft./lbs. of torque! I like the pic of the guy in the motorboat with the boiler & stack in front of him! He was flying!
I've always wanted to build a steam engine to generate electricity. You could throw all scrap combustibles in it to burn & have free power....BUT......the amount of money you need to spend to get the system up & running is just completely impractical. You need to have a tank that can handle not only 800 PSI steam pressure ( at LEAST -- might need a little margin of safety on top of that ), but also an 1800* coal fire burning beneath it. I'd imagine finding someone with the skill to build something like that would be difficult........then, if you do find him, what do you think the bill would be on that???? Then you have to build the pistons, cylinders, valves & rods, con-rods etc. etc. & the windings for the generator would probably cost as much as the rest of it!
I'm guessing it would be cheaper to buy a fully loaded Chevy Duramax diesel crew cab dually, remove one rear wheel & attach a massive chain & sprocket to drive the generator , & throw it in overdrive on jackstands.....
