Of course it can, I have seen functional steam engines that were watch size and run some that were 9000Hp (reciprocating). They did get larger, but not much before turbines took over the field. There is little scale effect for steam engines. What appears to be is the material capability and mass flow issues.
OK, it's a radial uniflow steam engine. They have been built before. It uses a flash type single pass boiler, the steam cars of the late 20's tried to do this, but the computer controls of the day were not capable.
It is a shame that they don't release any actual data. They don't seem to actually offer a unit of any output for sale at this time.
The steel that they are planning to use to hold in 3200psi 1200*F steam should be interesting. That has been a stumbling block for steam power plants for the last 50 years. 1005*F is kind of where even the stainless families get a little wilty. Titanium can do it, but I don't think they can do that and sell the engine at a profit.
It is still unclear why they want super heated steam in a reciprocating engine and it does not lubricate very well. That was one of the big reasons for going to turbines, they like super heat.
I'll wait for a chance to purchase a unit.
