And that's great, lets assume that continues, which there is no guarantee of, when would batteries be in the same ballpark as jet fuel? Lets call current batteries 300 Wh/kg and jet fuel 12,000 Wh/kg, that means, according to you, development would look something like: Battery Density: 2035 - 600 Wh/kg 2045 - 1200 Wh/kg 2055 - 2400 Wh/kg 2065 - 4800 Wh/kg 2075 - 9600 Wh/kg So in half a century we may see batteries approaching the power density needed.
