Long-distance energy transfer without energy loss will make it possible to connect more energy grids and sources together, so stuff like the saharan desert providing solar power to Europe, for example, suddenly becomes feasible. Maglev trains will no longer require lots of power to run, since they could utilize superconductor magnetic levitation. You could make super-efficient processors that wouldn’t really heat up at all. Superconductors are also key to quantum computers, so expect lots of advancements in that field as well. They will also make it much easier to build and run fusion power experiments.

Lots of tech in general would benefit from this discovery, stuff like MRIs, electric vehicles, space telescopes or particle accelerators would become way more efficient, cheaper and easier to produce.

Edit: also, check out this video by Isaac Arthur for some more sci-fi examples of what this tech can be used for in the future (discussed in the second half). It’s more space-colonization-focused and kinda like a thought experiment, but interesting nonetheless.

Reposting my comment from another thread to add a bit of context in case anyone’s curious.

So I read the paper, and here’s a tldr about how their material apparently gains its properties.

It is hypothesized that superconductivity properties emerge from very specific strains induced in the material. Hence why most of the discovered superconductors require either to be cooled down to very low temperatures, or to be under high pressures. Both shrink the material.

What this paper claims is that they have achieved a similar effect chemically by replacing some lead ions with copper ions, which are a bit smaller (87 pm for Cu vs 133 pm for Pb). This shrinks the material by 0.48%, and that added strain induces superconductivity. This is why it apparently works at room temperature — you no longer need high pressures or extreme cold to create the needed deformation.

Can’t really comment on how actually feasible or long-lasting this effect is, but it looks surprisingly promising. At least as a starting point for future experiments. Can’t wait for other labs’ reproduction attempts. If it turns out to be true, this is an extremely important and world-changing discovery.

Fingers crossed :)

No one is going to post news/articles here and then discuss them as they would in a regular post. It won’t get bumped up on the subscribed page if something interesting happens. Most of the comments here are going be about the megathread itself.

So this is effectively banning all the discussion concerning all of his companies. Which might be something you want to do, every community can decide for itself what kind of stuff they want to forbid after all. But I feel like it should be said directly, not via making a catch-all megathread.

Publications like these lower reddit’s future valuations though. I’m not sure whether a two-day uptick in users is worth that. My guess would be that it’s not.

I know, right? It’s so weird. In every single instance of some bullshit happening it’s easy to brush it off as incompetence or an attempt at profit maximization, but overall it feels a lot like some kind of targeted disassembly of whatever made the internet great and facilitated open discussions.

Poor Apple users kinda don’t have to deal with this shit

To save you a click, they used new material combination, thin films of hafnium oxide connected by barium bridges, to create a memory storage device that can encode states in between 0 and 1 to increase possible information density.

Also, the horizon line on their logo looked like a hair on my phone screen and it bugged me the whole time I was reading the article. I accidentally clicked on it trying to swipe it off the first time.

Reposting my comment from another similar thread ‘cause I think it’s kind of important to add.

Ok, so it doesn’t mention wet bulb temperature anywhere, so I went to figure it out. The first thing I was surprised with is apparently most of online calculators don’t take in values higher than 50C.

I couldn’t find the exact data about humidity for that day, but it has been 35-40%+ at a minimum for most days in that region, sometimes even reaching 90%.

So, 52C at around 40% humidity is 37.5C in wet bulb temp. The point of survivability is around 35, and most humans should be able to withstand 37.5 for several hours, but it’s much worse for sick or elderly. 39 is often a death sentence even for healthy humans after just two hours — your body can no longer lose heat and you bake from the inside. That’s like having an unstoppable runaway fever. And with that humidity it’s reached at 54C.

We’re dangerously close to that.

Why imgur though, why not link directly to xkcd?

Will not completely go extinct is not the same as fine. Even ignoring climate refugees and all that, let’s look at a simple thing: food supply.

The mathematics of global famine are quite simple. Add all the calories that earth produces in one day on average and divide it by 1500. That’s the amount of people that can exist.

Now, like 70% off all calories come from just 3 crops: rice, corn and wheat. As a good approximation, all of those lose about 10% harvest yield for each 1 degree C in temperature rise. It’s not really linear and is better at the beginning (so like 5% for the first degree), and much worse further on. But in general the approximation works.

Humanity now produces about 1.5x of the food supply we need, and even with super-optimized logistics we’re not going to get it lower than 1.2–1.3x population, since a lot of food gets wasted by cafes/restaurants and people themselves. Some just gets bad because it’s not consumed in time or takes too long to deliver or sell.

And with the current temperature rise estimations we’re looking at losing caloric supply for about 20% of the entire population in the next 20 or so years.

And that’s just one example. Have you seen rivers of dead fish in Australia and the states? For each species there is a point when the water gets too hot to hold enough oxygen or to cool down their bodies, and then bam — the whole species dies in a day. Right now, some algae, corals and plankton are like 1.5 degrees away from mass death.

It’s not really that “fine”.

Sorry for the rant.

The concept of emergence blows my mind.

We have this property in our universe where simple things with simple rules can create infinitely complex things and behaviours. A molecule of water can’t be wet, but water can. A single ant can’t really do anything by himself, but a colony with simple pheromone exchange mechanisms can assign jobs, regulate population, create huge anthills with vents, specialty rooms and highways.

Nothing within a cell is "alive", it’s just atoms and molecules, but the cell itself is. One cell cannot experience things, think, love, have hopes and dreams, or want to watch Netflix all day, but a human can.

The fact that lots of tiny useless things governed by really simple rules can create this complexity in this world is breathtakingly beautiful.

Kinda ties into your example :)
