To effectively replace coal-fired systems the e-Cat heating elements need to operate at 1600 K or so. I don't see that kind of performance yet - and I would like to.

In many of the tests it evaporated the water.  I assume the buyer can tack a turbine on the end if he wants to.  Also as I recall the reactor is at a considerably higher temperature.  Costs are said to compare very favourably with other power sources, I'm afraid I don't have the details to hand but you should be able to find them at pesn.com.  It is particularly useful in applications where heat or hot water is the aim of course.

Brian,

I meant the thermal efficiency of deriving useful work from an e-Cat's heat output. If it's just raising water temperature from 300 K to 373 K, then the thermal efficiency is at maximum (373-300)/300 = 24.3% but the actual work is likely to be much lower. Can't run a steam turbine, so would probably need to run a system using ammonia or some other volatile as the working fluid.

Kim makes a good point. The current thermal efficiency is very low.

That's a misconception. The reactor can now run in self-sustaining mode, so once it has got going no more energy has to be fed in (except possibly occasionally for stabilisation).
