Nothing about the NIF looks like a power plant to me. It's like the laser weapons guy and the nuclear weapons guy found a way to spend giant piles of money without having to acknowledge the weapons angle.
A lot of people think so, but the US government openly spends way more money on nuclear weapons than on fusion research. We'll spend almost a trillion dollars on nuclear weapons over the next decade.[1] The government's fusion funding was only $1.4 billion for 2023.[2]
So it seems more likely to me that some physicists figured out how to get their fusion power research funded under the guise of weapons research, since that's where the money is. NIF's original intent was mostly weapons research but it's turned out to be really useful for both, and these days, various companies are attempting to commercialize the technology for power plants.[3]
Yes. The NIF is a weapons research lab, not a power research lab.
The purpose of it is to show that the USA is still capable of producing advanced hydrogen bombs. More advanced then anybody else.
The '2.05 megajoules' is only a estimation of the laser energy actually used to trigger the reaction. It ignores how much power it took to actually run the lasers or reactor. Even if they update the lasers with modern ones there is zero chance of it ever actually breaking even. It is a technological dead end as far as power generation goes.
The point of the 'breakthrough' is really more about ensuring continued Congressional approval for funding then anything else. They are being paid to impress and certainly they succeeded in that.
However I suspect this is true of almost all 'fusion breakthroughs'. They publish updates to ensure continued funding from their respective governments.
People will argue that this is a good thing since it helps ensure that scientists continue to be employed and publishing research papers. That sentiment is likely true in that it does help keep people employed, but if your goal is to have a working and economically viable fusion power plant within your lifetime it isn't a good way to go about things.
If the governments actually cared about CO2 and man-made global warming they would be investing in fusion technology and helping to develop ways to recycle nuclear waste usefully. Got to walk before you can run.
It's been over 20 years since ive dug into nuclear tech pretty deep but - don't we already have breeder reactors and other tech that is low waste, safer and thus we could build modern (not based on nuclear submarine) reactors in the fission category and deliver cleaner power, today? Yes there is a lot of politics especially around manufacturing, production and storage of spent fuel so all of those are probably show stoppers no matter how safe they are in reality but we aren't invested in it.
