If we ever achieve nuclear fusion the sky will disolve and huge floating neon letters will appear saying LEVEL 2.

[@SpencerHHO]

She's right though lol. The last time something like 2MJ of laser energy yielded about 3MJ of fusion energy. Meanwhile the lasers used 400MJ of electricity so it's still a factor of 100 smaller than break even on the thermal energy. Once you factor in converting the heat from the fusion back into electricity you need to double it again. Then consider that this research is more relevant to making better nuclear bombs than energy and you begin to understand why those who actually understand past the hype aren't as excited. On another note we aren't trying to replicate the sun, we are trying to massively surpass the sun when it comes to the power density and temperatures involved.

[@jmeyer7102]

I can't wait to get my Mr. Fusion.

[@awesomelf8230]

My cousin is a nuclear engineer and he was in the navy and has been on carriers and in subs. The issue he really sees with fusion is that even if you get it to fully work, it spits out a ton of neutrons and they aren't charged so they just destroy everything. So until that issue is solved I'm not convinced. But all advancements and improvements are amazing!

[@Brotor_]

Fossil fuel companies are starting to get nervous

[@betergriffin2087]

Transmuting hydrogen into other stuff as a byproduct is also super useful

[@mnd3607]

So we are still 20 yrs away from fusion

[@TragoudistrosMPH]

Human technology kind of randomly advances, so it's hard to say! What do they say: an accident plus a prepared mind makes discovery. Something like that.

[@yeroca]

This particular technology is not suitable for fusion power generation, so not in 20 years, not ever. There are other technologies that are far closer, though. Look into the companies General Fusion and Helion.

[@stigcc]

Yes, we are 20 years away, and will always be!

[@pepsitwsit]

They achieved 50% more power than the laser beams shot at the pellet. But the lasers themselves have a 5% efficiency so nope , no positive net energy.

[@Deutritium93]

You don't discuss how the National Ignition Facility exclusively uses this technology to examine matter behavior under conditions seen in nuclear explosions in order to support U.S. nuclear weapon design and maintenance. It is not practical to produce large amounts of energy via nuclear fusion in this particular way. It only assists the research and recreation of the thermonuclear reactions found in the second stage of existing nuclear weapons since full-scale nuclear testing ended over 30 year’s ago.

[@Mars-ls5jj]

Hopefully Oil giants don’t try to propagandize people into thinking oil is better. This can be the future if people can yield enough energy to make this worth while.

[@1Dark.Paradise.Lost1]

They already do

[@evanhoffman7995]

Fission has existed for 70 years. It could replace all our fossil fuel consumption a hundred times over, and yet it hasn't. Why should we expect fusion to be any different?

[@wingman4668]

This time we only used the power of 290,000 homes at once instead of 400,000!

Hmmm… I heard the spiel about cheap energy from nuclear power in the late 1960s. Still waiting.

[@CarsCatAliens]

How fusion works,and the conditions needed to make it work blows my mind... When reading the atmospheres and temps My first thought was "What materials can handle that insanity"?

[@Spaghetti_policy]

They still have to figure out how to keep it going though. Apparently it burns itself out after a few hours.

[@mikeharrison1868]

No, I belueve the reaction lasts for just a tiny fraction of a millisecond.

[@zenkim6709]

Exactly -- the next major breakthrough will be to extend the fusion reaction for significantly longer durations. The holy grail, of course, will be an indefinitely sustainable fusion process that reliably outputs more energy than it consumes! 😍

[@SpottedHares]

Getting a Fusion reaction going hasn’t been to hard to do as a species as we first achieved it back 1952. It getting a sustained small scale fusion reaction that been the challenge.

"Fusion Ignition" is the goal. "Fusion Ignition" has not been achieved anywhere in the world. "Fusion Ignition" is where you produce enough electricity to power the Fusion reaction in a stand-alone system.

[@davidreinker5600]

So commercially viable fusion power is still just 50 years away?

[@matthiasknutzen6061]

It's progress yes but quite hyped. The whole system isnt clsoe to give net energy, what they mean by net energy is the energy put into the fuel which is a fraction of the energy put into the lasers. And there's not really any way yet to scale this into a powerplant IF it could give net energy. They are fusing tiny pellets, smaller than rise grain, the energy is less than a person on a bike.

[@C-Dub487]

[@cookieenthusiast6213]

It takes way too much power and it is debatable if the amount of power output was more. So they do need to work on scale. It is worth continuing the research but it is a long way off. I am still happy to see science try.

[@Leviathan_Art]

Well at some point we can't keep using fossil fuel, 🤷‍♂️ much better to do something. Test and test and test until we get the results we need.

[@whut9245]

It takes a set amount of power to startup all those lasers, running the reaction for a certain amount of time would yield a full energy profit, but its not up for debate whether this reaction ran a deficit or not, similar to the december one where 3.3mj was generated and 2.05 mj was put in.

Why waste money on failed ways to produce energy by fusion? We can do fusion, but the energy input cost to too high to be a viable source of energy. Or is expensive energy the point? The Sun produces its energy by fission of the hydrogen proton, in the photosphere. AKA e=mc^2 Fusion never produces energy on par with e=mc^2, only on par with plasma recombination.

@@BosnianHeisenberg the keyword is "successful". A commercially viable fusion reactor, hooked up to the national grid, making energy 24/7, 365 days a year (apart from occasional downtime for maintenance). The joke is that ever since the start of research, commercial fusion has always been 50 years away - and it still is today.

[@RWZiggy]

@@BosnianHeisenberg No, less than a percent of the energy put in was released. To exaggerate they only measure laser energy in compared to fusion energy output, but those lasers take more than a hundred times the energy in electricity. We are still mostly nowhere on the path to commercial fusion power. We should stop wasting money on it and just make square kilometers of solar array in deserts. We already have a working fusion reactor in the sky with billions of years of fuel.

[@sturggaming6759]

Why are you wearing makeup

[@justinmiller5660]

Its not that big of an achievement. A nuclear bomb gets way more energy out than energy put in. Talk to me when you can sustain the reaction without killing everything within 20 miles from radiation.

[@C-Dub487]

No no no... that's like saying an internal combustion engine makes way more power than is put in. A nuclear bomb is powered by plutonium. Plutonium is a fuel. Nothing more, nothing less. Just like gasoline powers the engine, plutonium powers the chain reaction in a nuclear detonation.

[@SomeKidFromBritain]

I dont think you fully understand what you are talking about.

[@michaelmckeown3164]

Fusion doesn’t emit any radiation there is no waste in fusion only energy. That’s why billions are put in for RR worldwide. You are correct that nuclear bombs do get more energy out than its manufactured embodied energy. However the energy burst is not controlled. When the explosion is initiated it is notoriously hard to control. Hence why we had nuclear bombs before nuclear fission. Nuclear fusion in LNL is super heated matter by lasers turned into into plasma all while pressuring it. It is different from a tokamak reactor because the plasma is contained using magnetic fields. It is extremely difficult and requires tons of math to imitate a fusion reaction however small and net positive amounts energy (more energy than was put into the reaction) Ie compressing gases and matter as well as heating it and firing lasers. Hopefully you can appreciate positive strides in science however small. Doctors used to believe that leeches and bloodletting would cure disease. Since then modern medicine has advanced to using fungus as antibiotic and using EMF radiation to check internal organs.

Lots of advanced technology is driven by defense R&D. Gps, microwaves, Fanta, kinematic physic advances and, cell phones, LEDs, ram jets, turbochargers, Insulation, and solar panels, and many more came from defense applications. That’s why the US spends so much on defense and technology. That and to protect freedom from hostile powers such as authoritarian regimes. The batteries Tesla (car company not scientists) used were originally a subsidized technology.
