You really can't read, can you. It's got its plasma to 300,000 degrees
K, and ITER have got theirs to 150,000,000 degrees K, about 500 times
hotter. It maybe some kind of milestone for OpenStar, but they've got
lot of milestones to go before they'll have a product that they can sell.

And they are still trying to fuse hydrogen or deuterium, which produces

Looks a bit like that thing Larking was making stuff for, laser ignition
Not much coming from that at all.

The US national ignition facitility was mainly intended to work out
whether nuclear bombs would go off. The nuclear fusion stuff is just
done to keep the scientists happy.

That was discussed here last year or so.
 

is trying to fuse hydrogen and boron, which doesn't produce neutrons -
if the machine ever works it will last a whole lot longer than hydrogen
fusion machines, which will be damaged by the stray neutrons they
produce, if they ever work.

 
Would be nice to have small portable power sources, for in the home and cars etc etc.

Of course it would.

Anyways after WW3 all will radiate, so who cares.

With any luck, there won't be a WW3.

The only thing that will come of it is that they find to make it work they will need an ever bigger one...

I like the Farnsworth fusor, fusion any kid can do.

Of course you do. It's much too small to generate more energy than you
have put into it to get the fusion to take place at all.

Being big isn't a virtue. Being big enough to do something useful is.

I have posted many times:
 'If you cannot do it with those small particles on the table top,
  then you cannot do it in a macnine the size of the universe.'

As to that Farnsworth Fusor, they complain the grid gets too hot
Nice, why not use thermocouples as grid, convert voltage up,
get break even or better?

I'd like to try, need a good lab and a good mechanical man, funding of course :-)
It is nice several projects are now looking for fusion, who knows?
Someone may hack it!
