No, fusion is not coming. Not even close.
The fundamental problems are not only totally unresolved but no one has any idea of how to solve them.
It's a giant vanity science money pit.
They recently ammounced some great 'breakthrough' of passing the 'unity point' of getting more energy out that they put in. For all of five seconds.
They put in 2 MegaJules and got 3 MegaJoules out.
Except they didn't. Because they ommitted to mention that to creat that 2 MJ of laser energy consumed a whopping 300 MJ of electrical energy.
So really, they put in 302 MJ and got out 3MJ.
But that doesn't make for headlines and getting more funding. So they excluded it...
Quote:
The efficiency of a potential fusion energy power plant remains to be seen. The reported fusion net gain actually required about 300 megajoules of energy input, which was not included in the energy gain calculation. This energy input, needed to power 192 lasers, came from the electric power grid.

It's called lying by ommisio and is the same basis as many climate claims.
But lets all say it together 'trust the science'.....
But thats not even the main issue, which is that a plasma at a million degrees melts anything nearby really very quickly. Even half a metre away, the thermal radiation just evaporates all earthly materials. You cannot sustain a plasma, You can't get new fuel in and you can't extract the energy out. Because anything you put in place to do that evaporated within a minute of firing the system up.
It's a big fat investment trap.
