Do we have a Fusion thread?

<< < (4/7) > >>

BrianHG:
How a Helium 3 fusion reactor works: (American funded)



Boring Helion program results so far:


BrianHG:
Proper explanation of what was achieved at the National Ignition Facility:


jonpaul:
mostly news noise.

See IEEE SPECTRUM article on the realization of fusion by laser

As always we are 30 years off..IF IT EVER WORKS.....

just another government waste of money

james_s:
The amount of money the government is spending on this is minuscule in the grand scheme of things. I think it's worth pursuing, there are lots of things that never would have happened at all if people had decided it was a waste of money to try because they would never work. I'd rather spend money on fusion than on bombing random countries.

jonpaul:
Rebonjour, was at LBL 1967, visits to LLNL in1980s,
LLNL laser program goes back to Star wars  SDI, conceived by Dr Edward Teller and funded with backings of President Ronald Reagan.
I toured predicesor Shiva/Nova, fantastic machine.

For perspective, one megajoule energy released if a jelly doughnut is throughly burned!

Even DOE, LLNL admits " wall plug efficiency" of NIF is nil as lasers are ((< 1% eff.
Need many shots per sec, at this time we have a shot every  month at best.
True purposes of LLNL NIF is classified nuclear defense tests. The fusion power is a façade to make the nuclear device research more palateble to the idiots in Washington DC.  NIF is indeed a tiny part of the $ is in the bloated and politically controlled 1T$ USA défense budget.

Easy solution to clean cheap energy..Voilà ! 

Conventional nuclear fission reactors! (70% power in France, no issues). We will see a working SSPS long before a NIF type working utilitaire power plant.

From an optimist in the nuclear age!
