The volumetric energy density is 60% of lithium ion batteries, but the energy density per kg is more like 75% since the batteries are lighter. Assuming that scales to the ev range, that’s probably sufficient for a lot of use cases.

I have one of these. The sous vide cooker itself is very nice and easy to use, I’d highly recommend it. The app is a bit clunky and not necessary to use the device. I certainly wouldn’t pay $2 a month for it.

The app lets you set a temperature and cook time, but you can also do this using the buttons on the cooker. Sometimes the WiFi pairing is finicky, so honestly I skip the app half the time. The app also lets you view and write recipes. I guess the big advantage is you can click “start cooking” and it automatically sets the device temp and time, but doing it manually isn’t much harder. I’m also not wowed by the in-app recipe selection, and generally just get recipes from the internet.

That’s too straightforward - this is google after all.

There’ll be a new product that integrates this feature and they’ll call it Google Slides, while rebranding the old “Slides” as Google Presentations. Then in a few years they’ll kill off the new Google Slides, leaving only Google Presentations and tons of confused users.

Is that actually the church’s stance? Like, has the pope ever said this?

What about one that pisses beer?

These are strange times for the Berry Club. Strange times…

I’m guessing they signed up for HP Instant Ink, a monthly subscription service that monitors the ink levels in the printer and automatically mails you refills.

If you buy an HP printer, they HEAVILY promote this and offer discounts/free trials. I declined, because fuck that, but I could see someone agreeing and forgetting about it.

Settle down, Jayden

It’s already been published. But it’s superconducting at 10 K. This is a new high temperature record, but pretty far from room temperature.

They’ve been doing studies of what would be required for ignition for a while, but have never demonstrated ignition using the Z machine.

If they did have ignition, there’s no way they would’ve let LLNL claim to be first and enjoy all the media attention.

Nah, the Z machine never achieved ignition. That doesn’t mean it’s not a really cool facility though!

The article is reporting on a published journal article. Surely that’s a good start?

Having YouTube premium means I can use it on any platform. I can use YouTube music on my phone with CarPlay and listen while driving, use the built-in YouTube app that hotel TVs have when I travel for work, watch things on my work computer, on my phone, or using my PS5.

You can use the YouTube music app with a standard (free) YouTube account, at least on iOS. But the audio only keeps playing in the background if you pay for YouTube music. And I think you can’t download music to play offline.

For what it’s worth, YouTube Premium ($14/ month) includes YouTube music and removes ads for YouTube.

Nah, that was ARPANET. The internet (www) was invented because particle physicists were too lazy to carry magnetic tapes with experimental data around CERN.

It’s important to read the full quote from Rivian’s CEO before complaining about $75k electric trucks:

“I think the reality of buying a combustion-powered vehicle … is sort of like building a horse barn in 1910,” he said. “Imagine buying a Chevy Suburban in 2030 … what are you going to do with that … in 10 years?”

He’s comparing buying a Rivian truck with buying a Suburban, which has a base price of $57k for the lowest tier configuration (LS) and a $76k price on the High Country configuration.

This is likely bunk.

There was a nice comment when this was posted on one of the science communities digging into the history and affiliations of the authors of this preprint: https://kbin.social/m/science@lemmy.world/t/249222/-/comment/1110464

Just by looking at the authors, this is not real:

Of the three, the first author (and corresponding author) and second author claim Q-centre as affiliation. If you check the webpage, it is not a research lab but just a commercial company selling this as a product. The third author claims KU-KIST as affiliation, but the only one I can find in google scholar has no background on superconductivity at all, and actually I can’t even find them as a current faculty member of KU-KIST.

If you look at the other paper they have in arxiv about the same, list of authors from the same Q-Centre, plus a last author from Hanyang university, but researchgate shows him as last publishing in 2006, so I assume long time retired by now. Not in the field of superconductors either.

I am looking for other work from any of the authors, and I can find none. Science is an incremental process, with some breakthroughs, sure, but incremental. Cancer won’t be cured in a day, and room temperature ambient pressure superconductors won’t just happen out of nowhere. Even room temperature superconductors at very high pressures aren’t really a thing, as the recent retractions of Ranga Dias’ papers shows.

As an aside, here is an interesting talk about the work that went into showing that the data was manipulated in those high-pressure room-temperature superconductor papers - as much as papers with manipulated data are a terrible thing for science, the fact that people will go to these lengths to prove them wrong is very reassuring. A paper that is wrong only misleads for a while, actual science pushes through and buries it eventually.

There have been A LOT of room temperature superconductor claims, thus far all have been irreproducible, either due to measurement error or likely fraud. I wouldn’t take this one seriously, especially since non of the coauthors have any previous publications in this field. That’s a big red flag.

I didn’t know it would come off like that
