A fluid can store solar energy and then release it as heat months later

They engineered this molecule to reliably fold into a Dewar isomer under sunlight and then unfold on command. The result was a rechargeable fuel that could absorb the energy when exposed to sunlight, release it when needed, and return to a “relaxed” state where it’s ready to be charged up again.

Previous attempts at MOST systems have struggled to compete with Li-ion batteries. Norbornadiene, one of the best-studied candidates, tops out at around 0.97 MJ/kg. Another contender, azaborinine, manages only 0.65 MJ/kg. They may be scientifically interesting, but they are not going to heat your house.

Nguyen’s pyrimidone-based system blew those numbers out of the water. The researchers achieved an energy storage density of 1.65 MJ/kg—nearly double the capacity of Li-ion batteries and substantially higher than any previous MOST material.

Not being hazardous is actually one of its benefits.

Major downside is it needs an acid catalyst to release the energy, you’re looking for how to simplify separating the acid later.

Research stage, so no claims about cost.

This is the second time I’ve hears about this tech, hopefully it goes somewhere.

[QUESTION] nonstick cookware?

https://piefed.blahaj.zone/u/uncommoncorvid posted on Feb 18, 2026 03:12

novice at cooking here. know the basics and can make some decent tasting dishes without the need of a recipe, but not enough to know the full ins and outs of cooking.

since i moved out of my parents’, i’ve been cooking with cheap pans pots and pans from ikea, and while they do the trick for most of my cooking, i cannot for the life of me make decent eggs without them overcooking and sticking, butter/oil help a little bit but not consistently. the electric range is def a hurdle to learn coming from gas, but most of my other dishes seem to come out fine.

anyway, i’ve been looking into some decent pans that meet the following criteria:
- nonstick without chemicals (teflon/PFAS/whatever)
- induction burner compatible, as i plan on getting a burner at some point
- (optional) comes in an 8in and 10in size
- (optional) oven safe

from what i’ve seen so far the “Analon EverLast N₂ Carbon Steel” seems like what i’m looking for based on reviews but i also wanted to ask for people’s opinions before making a purchase

The thing that works for me is allowing the pan to heat up quite a bit before pouring the eggs in. I mean, not searing hot, but you want it to make a little “tssssh” noise when you pour in the eggs. Allowing them to sit and cook a little bit before you stir seems to help, too.

That’s also why I don’t really scramble them very aggressively. The bottom layer needs to sit on the pan and cook, becoming a little solid, before I move them. When I do it that way, they don’t stick. It ends up being kind of like an omelette that I frequently ruffled up and then flipped at the end, rather than really scrambled.

A little fat, low to low-medium temp, but don’t put the eggs in the pan until it’s up to temp, keeping in mind that it’ll take longer with the heavy cast iron pan.

When my eggs stick it’s virtually always because I was impatient and put them in too soon. If you hear the eggs sizzling from the instant they touched the pan you should be good as long as the heat’s not crazy high, but if you dump those eggs in and the pan is quiet than that means it didn’t get hot enough in time and you can expect them to soak up the fat and stick.

What the other commenter said about waiting a moment to start scrambling is good too. I find that if I start stirring while the layer of egg touching the pan is still liquid (which again, can be for awhile if you didn’t wait for the pan to get hot), it’ll just stir the fat into the eggs instead of around them. So wait just a moment for at least that thin layer contacting the pan to cook before you stir.

I’m not sure I get what you mean. In every distro I used so far rsync did use ssh by default so it would honor everything I set in the ssh config.

Not everything however. For it to catch some options , for example SOCKS bridges, you have to use the SSH passthrough notation aka rsync -e 'ssh -F configfile options...' --rsync-options.... And ofc if you have to load a different SSH conffile, you have to use the passthrough for that as well, there’s no rsync native option to load a SSH conffile.

TIL the FCC fairness doctrine is different from the equal time rule.

Equal time rule hasn’t been enforced in decades. Get the fuck out of here with that nonsense.

This is what’s behind the spectacular FPV drone shots at the Olympic Winter Games

https://piefed.social/u/pageflight posted on Feb 19, 2026 01:47

The drone is equipped with a high-end COFDM transmission system that integrates directly with existing wireless broadcast infrastructure. This allows native HD HDR video to be transmitted, both progressive and interlaced, and enables the signal to be integrated into shading systems in the OB truck. For the complete RF chain, Dutch Drone Gods works together with broadcast service provider Broadcast Rental, which supports the technical team during live transmissions.

FPV pilot ShaggyFPV explains that other sports during the Winter Games are covered by different teams, using drones ranging from 2.5 to 7 inches. Almost all of these drones, however, use the same transmitter and camera technology. In total, around 25 FPV drones are active during the Milano Cortina Winter Olympic Games for live coverage.

“Twelve months of preparation and this is the result. Without a doubt the most difficult job I’ve ever done: flying in such a tight space, fifty times per session, consistently, with no room for error. And now two more weeks to go.”

The “government” is transgressing the constitution - the ‘pub senators and military leaders are too ?? to realize that if the rules are gone - so is their “authority”…. so, time for new senators and presidents and stuff… right? Right? This New Bizzaro land is fucked…

I hear you and I’m all for diving in—breaking things is half the fun.

If you’re after something straightforward for NAS software, another thing to consider would be vanilla Debian with Cockpit and 45Drives’ excellent filesharing plug in. I like the combo quite a bit.

Enjoy the journey!

Also using Booklore with 2 Kobos, works great!

Although annotation syncing isn’t supported yet, I believe there’s a pull request for it already.

“Systemd is great”, then systemdeeznuts and go use it. Don’t make it a huge piece of shit half-imitation of svchost.exe that forces incompatibilities, so we can fuck off and use our own shit if we want to.

I just don’t reply to assholes who intend to be such in a very narcissistic fashion by asking for information that they may merely shit in your face with answers to.

You, in that very name, are much more clearly self-aware of any shutting behavior that you make such great sounds to watch. Or at least, by those who like watching that shit. I did my homework while my brother watched that and then got to watching Ronin Warriors.
