Well, its not so much in making the bomb, but the particular ways of focusing the X-Rays and particular efficiencies in creating the tamper for the most velocity and thus most compression in the secondary. The key thing here is the Lasers a

Or it needs to pretend its about fusion as an energy source, to mask its really about creating and maintaining a stockpile of h-bombs that could destroy every city on earth.

Yes, but if you get into the details... The second stage of a bomb is the fusion in which a cylinder of hydrogen and/or lithium is encased by U-238. The primary stage, a trinity-like a-bomb, forces the cylinder to compress by its x-ray

The issue is, we've been able to get more energy out of a fusion reaction than put in for 60-70 years now. The H-Bomb is very good at doing that. You will say, yeah, but an H-Bomb is a one time use thing, and it has a habit of destroyi

It is interesting that there hasn't been many classification hurdles on something that is pretty explicitly weapons research. My guess is that they achieved high Q values a long time ago in classified research using mechanisms that wou

Most of the fission energy in an H-bomb comes from the massive amounts of neutrons created by the fusion bomb initiating a fission reaction in the U-238 tamper of the secondary. The primary is used for its X-Rays, which cause the incredible

One use for such a 'laser initiated fusion' is the LLNL (Teller) proposed X-Ray laser satellite from the Star Wars program in the 80s. The proposed solution then was to use the X-rays from an exploding bomb at the heart of a satel

To me this is the most important part of the article, “It’s a big milestone, but NIF is not a fusion-energy device,” says Dave Hammer, a nuclear engineer at Cornell University in Ithaca, New York. Herrmann acknowledges as much, saying that

Its so frustrating to see so many people not understand this means relatively nothing towards the goal of power generation. We'll see how many details are released to the public and other scientists and how much is kept top-secret. The

The issue is the NIF isn't trying to study power generation, their mission is determining the health of our weapons stockpile. This experiment is a lab where they can test different casings and different hydrogen mixtures and this prob

Caveat: This comment is derived from publicly available info. An H-bomb is a two part bomb. The primary bomb is a implosion plutonium bomb similar in make to the nagasaki/trinity bomb. It is theorized the Xrays from that bomb are focus

The purpose of NIF is primarily to study the effects of age on our nuclear weapons stockpile by simulating the x-ray blast of the primary nuclear device on the secondary fusion stage within an h-bomb in a controlled environment. Then we can

I think a lot of people now have calculated that it wasn't possible, but I wonder; 1) how much modern information, or information only openly available now, was used to determine that. 2) How long it took them to figure that out and wh

There is just basic h-bomb efficiency gains here. By lowering the energy requirement for the fission primary by finding more efficient ways to control/generate the X-Rays you can use a smaller and smaller primary. It also occurs to me
136.
by jboy55 4y ago
Yes, I think more research towards eventual power generation, rather than weapon testing, would be better.

The problem I have with this announcement is how limiting this technology path is to the future generation of power. If you look at the details, they imploded a sphere containing hydrogen with X-rays created by the interaction of the lasers
138.
by jboy55 4y ago
Its actually pretty good, since this is primarily weapons testing. The real money is being spent in the EU, where there is at least a chance of getting a sustainable fusion reaction.
139.
by jboy55 4y ago
This isn't for power plants, this is to model the efficiency of the second stage of a stored h-bomb in place of periodically exploding them, which we can't do anymore due to the test-ban treaty.

It is necessary since they banned the testing of nuclear weapons. Before they would do this kind of research by imploding a cylinder of uranium encasing a hydrogen core with X-rays produced by a "Fat Man" style bomb. Now they impl

There was a report, at that time, that the melting uranium mixed with water would go critical, as water would become a moderator not that it was flash into steam. The estimated yield was in the megaton range. It probably was a bad report, j
