If you notice, the chirality of the pasta plasma is always right-handed.

In June 1999 a rotating crane hoisted the target chamber and gently moved it to the Target Bay. It took about 30 minutes.

Fusion is so insanely far up the technology tree compared to fission because so much more needs to be done in order to achieve star-like internal conditions... outside of a star.  But step by uncertainly-funded step, it's being done.

I can't remember if "solar panels are fusion energy" is supposed to go in this list or another one.

Replacing the pellet of fuel quickly enough, at just the right spot, to maintain fusion will be interesting.

I could see a rotating disc where the pellets are fed into the system, but what happens to the pellet stand during the process? Does it melt/vaporize?

If they get 30-40% net positive usable energy with an "ignite-burn-replace-ignite" scenario, sustained fusion might not be necessary.

/20 years.

NIF is a test facility for very tiny nuclear weapons since we can't blow up Nevada anymore.  Civil research is just along for the ride.

CASIP's Shenguang II, which is based on NIF, is trying to do that though.

No one was predicting that electric cars and rockets that land and can be reused have been just 10 years away for the last 40 years.

They've been doing that with nuclear fusion for power purposes, at least as long as I've been aware of it.

Fusion (and flying cars for that matter) has a much higher credibility hurtle to clear than things like electric cars, which were first built over a century ago, and tail-landing rockets, which I remember seeing demonstrations of in the 1990s.

All intelligent people intuitively understand that.  For others, it needs to be explicitly spelled out for them.

Perhaps that was a bit unfair.  You could be a youngster who doesn't have decades of broken promises and breakthroughs that aren't under your belt.

So now we're only 15 years away from commercial fusion being only 10 years away?

Back in 1989 when we started our little company, we had a closet located next to the coffee maker that was labeled as the "Cold Fusion Lab" as everyone had to have one in those days.

You know the difference between a physicist and a chemist?

A physicist doesn't believe he's accomplished fusion and surrounds the experiment with lead bricks.  A chemist believes he has and surrounds the experiment with styrofoam.

rnatalie: A physicist doesn't believe he's accomplished fusion and surrounds the experiment with lead bricks.  A chemist believes he has and surrounds the experiment with styrofoam.


Sorry. Could you walk me through this joke?

The physicist who doesn't believe they're being exposed to neutron radiation puts lead shielding up.

The chemist who does believe they're being exposed to neutron radiation puts hydrocarbon shielding up.

Is the joke that hydrocarbon shielding is better than lead? It's rather good at stopping neutrons.

Once again, LIF is completely irrelevant to producing usable fusion power.  It's a fun physics playground with some relevance to nuclear weapons development.  Nothing more.  LLNL's PR machine is working overtime on getting these stories out for the sake of future funding.

I'll let them speak about what they do there:

They do many things but they're not shy about what they do.  You can see more for yourself:

https://lasers.llnl.gov/about/what-is-nif

If you want to debate what they do there, find their contact page and debate them directly.  They might get a kick out those replies.

thehellisthis: If you want to debate what they do there, find their contact page and debate them directly.  They might get a kick out those replies.


So, on the page you linked to, where they say:

Energy Security
NIF experiments will provide the scientific basis for a revolution in energy production. Inertial fusion energy offers the potential for virtually unlimited safe and sustainable clean energy by harnessing the power of the sun and stars.


how does that fit into dark_matter_doesn't's comment that "It's a fun physics playground with some relevance to nuclear weapons development.  Nothing more."?

Perhaps you should like to go through their contact procedure to tell them that they're not actually doing what they say they're doing.
