In the early morning hours of Aug.13, Lawrence Livermore's National Ignition Facility (NIF) focused all 192 of its ultra-powerful laser beams on a tiny deuterium-tritium filled capsule. In the nanoseconds that followed, the capsule imploded and released a neutron yield of nearly 3x10^15, or approximately 8,000 joules of neutron energy—approximately three times NIF's previous neutron yield record for cryogenic implosions.

We have the power!
That's a very big 'pew'
And it'll be ignored as an energy source until the oil wells run dry.

Hardly a viable energy source, have a look at the numbers...
aprox 8,000J energy out from... lets see
1.8 MJ 1,800,000J in....
Not there yet...

Is it even commercially feasible? At this point that is.
Currently Torus Fusion is more viable, the main problem we have with it... how to get the fuel in without disturbing the magnetic feild causing the plasma to touch the sides and cool down...

How much fuel can one contain?

We still pump more energy into the machine then we get out of it, so no
At least i didn't see any mention of it, but if they managed that they would be screaming it across the rooftops

[I]Every fucking thread.

This isn't even aimed at energy applications. Laser fusion basically won't work for power production. It might work for, say, fusion rockets, but the cost is just too high and the energy extracted too hard to collect.
The National Ignition Facility isn't trying to develop nuclear fusion power - they're doing nuclear weapons work without breaking any of the dozens of treaties against nuclear testing.

It depends if ITER works as planned, that would be the best starting point for any fusion power, of course there are some technological advances and major engineering problems to overcome but it could well be done in the far future.

I know we should just stop people from posting the same valid thing twice.
Excuse me while I go have a quick fap.
Awesome, Hopefully it leads to some breakthroughs.

Tokamaks in general are a better idea for power generation. Rather than having the ignition source be external, tokamaks are in theory self-sustaining. They're also more controlled reactions, and are contained in a way that should make extracting excess power easy. Yeah, there's a ton of engineering problems left to solve, which is why we haven't actually gotten self-sustained fusion from them, but there's at least a theoretical plan for how it all will work.
I wonder if they have taken into consideration doppler cooling/heating, may increase/decrease ignition efficiency:

Sad but true; we have yet to work out how to gain more energy from a fusion reaction than what is put in through the ignition sequence. If it's a matter of the pellet burning out too soon, why not have the pellet be at the heart of a larger fuel-sphere, acting as a primer to excite and ignite the fuel around it and create a temporary artificial sun?
It'd be kinda like how a bullet works, only with "fusile material" (I don't know the name for materials that can sustain a chain reaction of nuclear fusion, so I played with the word fissile); the lasers act as the firing pin, the pellet acts as the primer, and the fuel-sphere enclosing the D-T pellet acts as the powder charge. Can't hurt to try, at least?

you're an idiot generating energy from laser fusion is a violation of the laws of physics

It would probably be possible to build a plant from our current technology, it would have to be massive to deal with poor plasma behaviour so it would be very uneconomical. Even the NIF had problems with ignition because plasma simulations were not accurately representing what actually was going on. I think the main aim currently is to increase efficiency and to make the reactors smaller and therefore more economically viable, this is where the engineering problems kick in

In medical threads, every breakthrough gets at least one "and its never heard from again" despite the breakthrough being [I]nowhere near[/I] human testing, let along deployment and mass production.
And fuck, in this case, [I]this wasn't even an experiment for power production, it was WEAPON TESTING.[/I] But REGARDLESS, every single energy breakthrough is still MILES from viability as alternative power.
In other words: [I]Fucking shut up and wait for them to finish developing it.[/I]
At least they're making progress.

NIF wasn't designed as a powerplant testbed, its only designed to test and optimize fusion fuel casings, that and something to do with nuclear weapons

Shit, did someone tell this to the scientists working on this, they might want to find out before wasting more time

thermodynamics says you can't BUT thermodynamics does NOT take into account atoms and the strange world of quantum physics.
