minus-squareHotdog Salesmanlinkfedilink4•4 months 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
