Very interesting #tiny little #lithium #batteries that can be #soldered to a #pcb https://hackaday.com/2022/11/15/new-part.. I would definitely be interested in these. Could make for a nice #watch of #portable #device #battery , espeically when you use a few of them!
Huh, looks like #nasa almost lost #contact with their little #helicopter , but then #resurrected it from the brink of #death https://arstechnica.com/science/2022/05/.. Those #batteries are getting *ultra* #cold on #mars . It probably won't last much longer...
#aardvark raises a great point about #ev #batteries and #electricity #infrastructure - including in #nz which has a lot of #renewable #energy https://aardvark.co.nz/daily/2021/0812.s.. It just doesn't seem well thought out, I really suspect there will be massive implications.
