Apart from this, even if you can get the flame to work in a boiler
designed for coal, you will only get the 40% thermal efficiency of a
coal plant. Whereas, if you burn it first in a gas turbine and then heat
steam with the exhaust you have approaching 60% thermal efficiency.
Although we used to think of "jet engines" as being expensive, high tech
kit they are now mature technology.

I think they probably count as mature, expensive, high tech kit :-)
