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.

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.

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

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

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.

This at scale with a room temperature superconductor.

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

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%.
