As far as I know, no hot fusion reactor has run with a COP<1 for any appreciable length of time. Even the latest project, the $25 billion ITER will only run at a COP 1.3 for ten minutes - if it meets it's target. Obviously hopelessly uneconomic. Are you saying there are better systems out there and ITER is a step backwards?
There are several other systems out there, like Polywell, that are not funded properly and probably decades away if they ever work. I've not been following Lockheed and don't know how that is doing.
Do tell us of this new system small and cheap enough to power a house
Adrian:
Would you care to state which of my statements trouble you and your reason for objecting? Your arguments above are straw men, if you read what I said carefully.
I also suggest you consider context, and note that I only promised to provide better evidence for my statements than Axil has for his. That is a low benchmark.
Now, more seriously, for a possibly better H-B system, I suggest you look at Hora's work.
