What scientific discovery, which could actually happen in the next 5 years, would have the most impact in our lives in you opinion? (lemmy.ml)

Everybody is going to groan, but solid state batteries. That would be a huge sea change, not just for cars, but also air travel.

I have good news for you, then. We're now past the "discovery" phase and we're at the implementation phase with solid state batteries, as you can actually buy production models: https://yoshinopower.com/

Yeah but they're not there yet in terms of mass deployment and that's still going to take some more technical breakthroughs. They'll get there eventually but there might be some new discovery any day that would greatly speed up the process.

Yes, it's brand new, but the mass manufacturing difficulties have been resolved. We might not have whatever future iteration of the technology you're looking for, but it is unquestionably here and future developments are likely to be incremental rather than revolutionary.

I don't know about air travel. For comparison, Li batteries are about 200-300 Wh/kg, with solid state reading 3-4x that.

Jetfuel is 11000 Wh/kg. Hydrogen is 39000 Wh/kg.

By volume they might have an advantage but planes tend to care more about weight
