The disconnect between "Fusion" and "Nuclear Fusion" reminds me of when the term NMR was changed to MRI so that people wouldn't be scared of the word "nuclear" in the imaging machine that is going to scan them. Maybe it should be called "Particle Merging Energy" :D
or "terrestrial solar energy" 😁
People are really stupid
@@human_isomer Clever!
To be fair though NMR doesn't have much to do with anything nuclear fission or fusion, only Nuclear Magnetic Resonance spins.
Never overestimate the average knowledge of science amongst the general public.
Very good ❤
Great video, thanks! Informative and well presented, very good use of imagery and videos. Love the earrings :-) Keep up the good work FIA!
And not a single difficult problem mentioned, where is the fuel source, what is the neutron gain, what about when the walls start to get irradiiated by neutron flux in the presence of tritium in the proximity of liquid helium cooled superconducting magnets near a 100M K plasma and a water loop all in the same device, its so simple in the comic book version.
@@johnjakson444 If we went through life as negative nahsayers we would all still be living in caves. :-) Perhaps you should import some optimism in your thoughts on this topic. Of course there are problems, and of course it is hard, they are not trying to bake a cake here. In any event, they are providing a fusion market update for our benefit, not providing a presented thesis on how to build a fusion reactor and solve all the problems that currently exist.
Dr Keslerrrrrrr! :D
This updates are really appreciated.
The emotional baggage related to nuclear power is huge. If one country leads the way everyone will notice the benifits though. Looking forward to seeing humanity make a star.
I would’ve thought it was France with their Fission plants. 🇫🇷
No one country will ever master fusion technology, but it only takes a good university to master a basic fission power plant, and when pressed, fission plants can be rolled out in a single decade. During the oil crisis of the 70s, France completely switched from burning oil for power to having a large nuclear fleet of power plants in a decade.
6th: TH-cam’s algo finds out that a gorgeous woman talking about nuclear fusion increases people's belief in the technology.
I thought fusion and nuclear fusion was the same. I learn something new everyday.
Fusion cooking is popular among the cooking shows .
Getting my hopes up of seeing commercial fusion in my lifetime... we need to spread the word that this isn't the Godzilla kind of nuclear...
well go to college and learn about fission and fusion physics, in bombs and power generation, then you will find out how eassy it all is
@@johnjakson444 Making a nuke is easy because you let it all out... fusion is like a controlled wet fart, you never can tell if it is safe to push it.
Fission and fusion are inherently linked, there are some internal processes that are an exact mirror, fission has beta decay of electrons, fusion has beta decay of positrons.
Fission is about 1M times more energy dense than chemical energy, fusion claims to be about 3.5 better still, that tiny extra amount has a huge cost though.
Fission would have very high perfomance at only 1000K. Fusion is practically impossible at 100,000 that temperature.
They both produce neutron flux, fission has a neutron gain of about 2.5 while fusion has massive losses.
Fission produces tritium as a waste product, fusion usually requires tritium but has no practical sources for it.
Both can breed fuel, fission can breed fissile material into fissionable material, ie thorium232 or uranium238 into uranium233 or plutonium239 resp.
Fusion can in theory breed tritium from lithium but has a gain a fraction of 1. Berylium could double that but it is still less than 1. Most of the tritium isn't even burned.
Neutron flux in fission reactors is used to make heat in water or other coolant as the neutrons are slowed down.
Neutron flux in fusion reactors must hit the containment vessel and irradiate it turning it into nuclear waste. Some of that flux might produce tritium but not enough to sustain reaction.
Fusion has to do many impossible things at the same time, very high temp plasma, irradiated hot walls next to cryogenic cooled magnetics with a water loop inside the vessel walls.
Fission reactors can use simple physics to run in stable mode, no computer control is generally needed, other than monitoring.
Fusion reactors are inherrently unstable and require computers and now AI to learn how to control them.
An elementary fission reactor that produces as little as 1MW of continuous heat is a very low cost university level effort.
An elementary fusion reactor that produces as much as 1MW of continuous heat is a very high cost world level effort and won't succeed for another 1000 years.
Do let the world know when tritium is allowed to burn in a fusion reactor on a continuous basis, and tells us about the source of the tritium and damage done to the vessel.
In thermonuclear weapons, a fission device always triggers a fusion component which then further amplifies the second stage of fission. Fission, fusion, fission play well together.
If public perception of fission is negative, wait till they understand the ramifications of fusion.
I have to wonder why no one is talking about Lithium Deuteride as a fuel, no breeding needed, but its used in thermonuclear bombs so is kinda top secret.
Well the tritum problem is easily fixed... use more abundant heavier elements and raise the chamber temperature they don't use hydrogen isotopes in thermonukes... instead use the lithium 6 and fission bomb splits it into hydrogen isotopes and provides the heat/pressure to recombine it all.
6:30 they should use a 3 D printing machine to build it .
why is that, because 3d printing is hip. besides machines like ITER are truly massive
@@johnjakson444 Because the chamber has pretty complex shape . Rocket Lab prints their rackets with a 3 d printting machine. They are massive too
@@pingvin2-zw5oe If you knew anything about 3d printing you know even in sintered metal there are huge voids... meaning holes in the reactor walls not a good combination ... so if you got any idea at least think it threw, otherwise I will call you a M0R0N.
How refreshing. Real news from a real scientist. Thank you. 🙏
