Reply to comment by PragmaticSquirrel in NASA invents ‘incredible’ battery for electric planes by HaikuKnives
Nasa claims 500 Watt-hours/kilogram in their solid state battery, or in other words 1.8 MJ/kg. Kerosene is rated at about 42 MJ/kg (and gasoline is about 44 MJ/kg) so there's a factor of 20 between them. Thats actually not as bad as it sounds, considering that electric motors are much more efficient at energy conversion than combustion engines that would be used to drive a prop.
