Built in a factory and transported to wherever needed. Apparently safe too. Nuclear fusion NOT coming into the electric grid anytime in the two decades. The lab produced about a net energy of 280 watt-hours during a 100 trillioniths of a second with the government spending over $700 million per year. If that level of funding were used right now, I bet the current US national grid would be 100% alternative energy. 2 1 Link to comment Share on other sites More sharing options...
spidermike007 Posted December 14, 2022 Share Posted December 14, 2022 People simply put too much faith in technology, or grossly over estimate how advanced we are, as a species. I believe we are 300 to 500 years away from a viable nuclear fusion technology. Nobody has even come close. An experiment that lasts a trillionth of a second barely registers. 2 Link to comment Share on other sites More sharing options...

Tug Posted December 14, 2022 Share Posted December 14, 2022 Hopefully it will pan out (become usable in the real world)and become another arrow in our collective quiver to address this problem personally I’m rooting for a really good battery to store energy there’s plenty of it out there for the harvesting just mediocre ways to store it that’s the key imo 1 Link to comment Share on other sites More sharing options...
TKDfella Posted December 14, 2022 Share Posted December 14, 2022 Well, as the Lab scientists said , it is a significant step forward. With Lasers they managed, '...for fractions of second...' to get an ignition and 1.5 times the energy of the Lasers was achieved. There is still a long way to go; a sustained excess output; designing a delivery system to supply communities and so on. 1 Link to comment Share on other sites More sharing options...

There's a company called Form Energy, that essentially uses iron, which is very cheap, to store power. Other companies are doing that was well. Also, zinc, another cheap metal is being used for storage. Zinc-8 is one such company. A really interesting advance comes from Influit which has created a new kind of low cost flow battery. Currently, influit claims it can hold twice as much charge as a the best lithium batteries, but they say the next generation will be able to hold 4 times as much. With that kind of power, it can greatly increase the range of electric powered aircraft. It can also be used much the same way as fossil fuel is used. The charged liquid can be pumped into a container in a plane and when it's charge is relatively depleted, the liquid can be pumped out and replaced with freshly charged liquid. I used planes as an example because it would require a huge infrastructure investment to adopt it for EVs. Link to comment Share on other sites More sharing options...

Crude oil will pick around 2045 with some 45mln barrels per day. 45 million bbls per day?? Have you been looking at a chart from 1968? We are already at 100 million bbls per day or more than 1,000 bbls ever second! 1 Link to comment Share on other sites More sharing options...

rabas Posted December 14, 2022 Share Posted December 14, 2022 (edited) OK, the NIF fired 550 WHr of laser energy into a spec and got 830 WHr out. Although a milestone, they forgot to mention the whopping 83,000 WHr of grid electricity used to fire the lasers. Just wait for that electric bill. I thought mine were bad. Such omissions have long been a problem in the fusion industry as theoretical physicist and youtuber Sabine Hossenfelder explains here. If so, then why so much hoopla? Maybe it is to impress Mr. Putin as someone suggested above. The NIF is one of a few super high technologies the US uses to ensure it's aging nuclear weapons work. Mr. Putin has no such high technologies at his disposal. The only thing he can be certain of is that US weapons will work, he should avoid going down the nuclear road.

The NIF role in nuclear stockpile stewardship There are always lots of omissions in these things...take the cost of building materials and maintenance for a start. Nonetheless, trying to recreate conditions similar to reactions in the Sun in a controlled situation is no simple feat and brings fantasy a little closer to being reality.

That was for the cost of building and running a renewable plant vs just running a fossil fuel plant that's already built.

ballpoint Posted December 15, 2022 Share Posted December 15, 2022 If you had been in Kittyhawk on December 17th 1903 watching a heap of wood, canvas and wires briefly hop across a field, and claimed that 65 years later someone would fly to the moon, they probably would have laughed at you. When Lise Meitner and Otto Frisch discovered nuclear fission in December 1938 - something requiring neutrons, which were themselves only discovered in 1932 by James Chadwick - who would have guessed that, just four years later on December 2nd 1942, Enrico Fermi and his team would produce the first controlled fission chain reaction, and on June 27th, 1954, the first nuclear power station to supply a national grid would open in Russia? Never underestimate the speed of technology development once a major barrier has been crossed. (Especially one that was crossed in December). 1 Link to comment Share on other sites More sharing options...

cleopatra2 Posted December 16, 2022 Share Posted December 16, 2022 To the OP The description of breakthrough is disengenious. The ability to produce more energy than supplied was always going to be achieved. This marks a milestone in reaching that point. However the real challenge is overcoming the parasitic energy required to reach that state. Some 300MJ was needed to power the lasers. Thus the actual energy produced represented under 1% of the total required. Link to comment Share on other sites More sharing options...

When a product that is produced for $10 is sold for $300 because of royalty tax, windfall tax, green taxes, CO2 taxes, punitive taxes, we are a little beyond your average VAT tax rate. Cheap fossil fuel is paying for a lot of the benefits we take for granted, whether we like it or not. 1 Link to comment Share on other sites More sharing options...
