minus-squareDiplomjodler@lemmy.worldlinkfedilinkarrow-up6arrow-down3·2 years agoYeah 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.
minus-squareHotdog Salesman@programming.devlinkfedilinkarrow-up4·2 years agoI 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
