Room temperature superconductors are right up there with fusion technology. Both are going to dramatically change the way the world works. Lossless transmission lines will save so much energy.

If the recent Korean paper isn't a scam it's pretty huge. Even if it isn't as big as announced (like a very low but positive resistance) it can already be a game changer for some applications

Assuming it's real, and depending on the future size, it could do faster CPUs without heat loss. So you would pack more silicon more densely without worrying about waste heat. Transmission lines would be more efficient. We lose something like 30 to 40% of our generated energy to transmission lines. So massive massive if it's true

total upgradable laptop like Framework 16

Micro LEDs.

Consider an OLED, but no drawbacks, lower power consumption and no burnin. Already available but currently extreme expensive. (Samsung in korea sells one if i recall)

Solid state batteries.

More range on electric cars. Faster charging. Lower (or no?) Risk of fire, if poked. (Reminds me of the old subreddit "spicypillows"). Supposedly arriving in toyota cars by 2027.

Carbon capture technology. Because the world needs it bad

I'm hoping suncells and batteries will become really good, so it's possible to drive your house electricity on only the sun. Would be truly liberating.

it is already something you can do, if you put enough solar panels

[–] [email protected] 2 points 1 year ago (1 children)

Yeah I guess but then you need a big roof probably. I was hoping they could be more efficient to double their performance, so half the space could be used (and possible half the cost).

But we will see :)

There is not much room for optimization left. Best solar cells get close to 23% efficiency, apparently the current theoretical maximum is a little over 30%.

If it's real, the new room temp ambient pressure superconductor (LK-99)

Especially because if it is real it can likely lead to an entire new class of materials, not just the one

[–] [email protected] 7 points 1 year ago

If it makes it out of the lab and can be manufactured at scale, it could revolutionize every industry that uses electricity at all, and that is essentially every industry. I look forward to the day I can replace the copper wiring in my house with superconducting NM wire.

[–] [email protected] 6 points 1 year ago (1 children)

current one: LK-99, also new types of batteries/energy storage. It would open ways to improve a ton of things.

[–] [email protected] 2 points 1 year ago

Seconding the new batteries! That's my major one.

AI, especially as it relates to completing daily tasks. I cannot wait until an AI can efficiently sort, delete, and categorize my email so I don't have to deal with all the junk and FYI emails.

[–] [email protected] 1 points 1 year ago

Ai. I have so much to say. At the moment 99% of my talking is in my head with myself. I would like to have an ai that I can interact with day to day to keep me sane.
