minus-squareJohnDClay@sh.itjust.workslinkfedilinkEnglisharrow-up3·2年前Yup! It has really good gravimetric energy density, but really bad charging efficiency.
minus-squaredrathvedro@lemm.eelinkfedilinkEnglisharrow-up5·2年前Not THAT bad, really, it potentially has a much better mileage-to-weight ratio and sidesteps the issue of lithium recycling and politics
