Every week with the "miracle battery!" headlines. This has been going on for ages and I'm sick of it.

[–] RaoulDook@lemmy.world 24 points 10 hours ago (2 children)

Sodium-ion batteries are not hype though, they are in production use in multiple industries already. They are generally superior to Lithium based batteries in all regards, with the exception of having a bit lower energy density. An equivalent LiFePO4 battery might be 70-80% of the size for the same storage. It's not a big deal for large applications like cars and solar storage.

Yeah, the advantages of all these sodium batteries, in my mind, is that they are stable and rugged enough to build up a backbone of a energy storage system for a grid. I'm seriously thinking about them for my house, in the UK.

Yes, I am very intrigued. For something the size of half a shipping container I could power my house for almost a month. This is of course fantasy because I don't have $20,000 to throw down. But combine it with solar cells that have gotten really cheap and you could indefinitely power your house for next to nothing.

Cool.

Right up there with "cause/cure for dementia found"

"Dyslexia for cure found!"

350 page study concludes some people spend too much time reading.

We found the cure for Alzheimer's but can't remember what it was. I think it began with a "c". Who are you?

It's time for your nap, Mr President.

cure for dementia found"

The US government could use some of that these days.

Charged with fusion power! From space! Made from privately mined asteroids!

[–] village604@adultswim.fan 1 points 8 hours ago (1 children)

Charging a car with fusion power is actually feasible. But it'll take more energy to keep fusion going than it creates.

[–] HugeNerd@lemmy.ca 1 points 7 hours ago

Sure and I guess you could charge it by using a PC's cooling fan in reverse and blowing on it too.

[–] Regrettable_incident@lemmy.world 1 points 10 hours ago

And it's got electrolytes!
