Look out! Communists are coming for your toothbrush. Better vote for harsher penalties for modifying stuff you bought. The DMCA still allows throwing away or disconnecting the computer locking you out of your heated seats.

Yes, many much easier ways. A propane tank for one. Wet, high CO2 methane is really hard to make explode.

Do get a CO detector though.

You can buy gas from anyone. Even make your own in a digester.

Your gas stove is not cryptographically locked to one gas company.

Spain and china managed just fine. Rail costs way less than 20 lane highways.

Worse than that. It’s more along the lines of asserting that they are happy with the financial arrangement and “jokes” as per the status quo, and that they stand by him and his decision to advertise their product for money on the “apoplogy” video. They’re making fun of the ones raising the issues, not linus. Even further they’re trying to milk to controversy for attention.

This is them condoning the behavior and showing their support for the channel in their weird cringey way. Not a condemnation.

Her response was unable to do nearly as much damage as the article. The stakes were much lower for the vice editor and her platform had much lower reach.

I’m not sure if the time scale would be measurable. Nanoseconds at most. But the relevant part is that it’s ignition.

A device to harness inertial confinement fusion would work very very differently to a magnetic confinement one if that were the goal here (it’s not, it’s a weapons research facility). Essentially heating something up a lot in milliseconds and then extracting the heat over hours to months.

This research comes frim the llnl weapons complex: https://wci.llnl.gov/

There is an international treaty against nuclear arms testing, so as new weapons and platforms are developed there is no way to expose them to the conditiona they’d encounter if they actually had to deploy nuclear weapons (or operate in an environment where they are being used such as trying to take out the other bomber that is on its way to destroy your other city while the first city burns).

In addition to the enormous military budget, They take large quantities of civilian money via the DOE because they pay lip service to it being “energy research”. This is the part that is objectionable.

It’s a cool thing, and arguably necessary given we recently got to see what happens when a country bordering Russia gives up its nuclear weapons altogether, but there is little application for energy. It may also see the development of some micro-fusion warhead with no fission component which is technically a nuclear bomb, but nigh-impossible to make if you don’t have the US military budget so they’ll use it anyway and say “nuh-huh!” when anyone objects.

Either the technology is highly limited in the volume where the reaction is self sustaining, so the machine as a whole will never break even energy-wise, or it is not, and every inertial confinement generator produced is essentially a weapon of mass destruction that the US will never let exist outside of the control of nuclear armed countries.

There may be some limited application to energy, but it’s a stretch (essentially it would look like asking the US military nicely to come set another bomb off in your artificial geothermal reservoir every few months). It will certainly never be deployed in a non-military mobile application (which rules out most of the use cases where renewables are not strictly superior).

Except this one isn’t basic physics research. It’s an end run around nuclear weapons treaties to test how missiles and planes respond to H-bombs going off nearby.

It could have an energy application (maybe), but given that the targets are ludicrously expensive, the most viable power plant would resemble the attempts in the 60s to use bombs in underground caverns to heat things up and put essentially a geothermal plant on top. Except with a laser detonator rather than a fission one. Chances of making it economically viable or reliable are slim.

Terrestrial fusion achieves very little that using the existing fusion generator we have does not do better.

Evidence that the class of materials is a thing is decently solid so far (but will still take a few months to confirm).

The hard bit of finding a process or another material in the class with a yield of more than a couple of milligram specks per kg of input starts after that.

Plus even then, the anisotropy (it only works in one direction) will give it some odd limitations. Still really cool though

Then…stop giving it by making inane, tired, cliched comments. And stop blaming shitty journalism and mandatory PR department fake hype for grant money on the scientists. Downvote and move on.

Each breakthrough had elements that were messy and complicated and once you break through the hype and look at what the breakthrough actually was, you can see they’re in hearing aids, and single use applications and many of them (even ones not originating in lithium batteries) are now in lithium batteries.

Hence why they went from barely more than lead acid in energy density with abysmal lifetimes to at around 90Wh/kg and <200 cycles to 500Wh/kg for pilot-scale (still larger than the total scale of lithium in the early 2000s) commercial batteries that do 1000s of cycles, charge ten times as fast and cost a tenth as much using no precious or rare earth metals and a 20th of the lithium. 2015-2020’s breakthroughs are gearing up to give us 700Wh/kg expensive batteries and 160Wh/kg dirt cheap sodium batteries.

The breakthroughs happened and are in mass production, just because the charge carrier is the same (with good reason) doesn’t make the other parts the same. Stop focusing on a single word as if that defines the entire thing.

That saie, this 'breakthrough" is pure hype. The concept is interesting, but the suggested application of residential energy storage is worse than a sodium ion battery by every metric.

Completely changing the construction method of the foundation of a whole house, making it out of 90% cement/10% electrolyte (releasing 200 extra tonnes of CO2) rather than 20% cement/80% gravel and increasing costs by tens of thousands for the same effect as a 70kg $2.5k rrp battery (which will be a 50kg $500 battery in two years)?

Doesn’t seem huge other than in the literal size sense.

And everything is very different from when NiCd was the dominant technology. You’re welcome.

Nah. Give tesla the same number of points everyone else gets on their license. If the company runs out, no more cars controlled by tesla on the roads…

It won’t be your hardware in a few years if this goes through. The code will run in a secure enclave and you won’t be able to access your bank or log in to government websites if you control the hardware.

Bifaciality isn’t new or limited to perovskite based PV. Ground reflection is also not the only source of indirect light.

This article is very bad, but bifacial panels are starting to dominate the industry for good reason. The backside gives a 5-20% boost in total annual yield (which is worth it on its own), but more importantly that boost is skewed towards times with low direct irradiance (such as cloudy days). This reduces the amount of storage required.

It also allows other orientations. Vertical installations have huge advantages including better compatibility with agrivoltaics, generation skewed towards times where low tilt panels don’t produce (morning-evening for east-west and winter for north-south), better dual use, and lower racking cost. Glass-glass encapsulisation is also more durable and this alone pays for most of the added cost.
