do you have any references to back these statements up? I am not an expert but I did read in a hacker News comment that the energy density of gasoline is about 14 (reading that article, its 50) times higher than a "normal" battery.

if that is true (I do not think that he left references either) then I would think that your statements seem less plausible.

a replier who later deleted their comment left a reference saying the energy density is 50 to 1, comparing lithium-ion battery to diesel: https://www.batterypowertips.com/comparing-ev-battery-and-fu...

Combustion aircraft also benefit from the weight reduction as fuel is consumed.

While that’s true, and makes a huge difference for rockets, it only makes a relatively small difference for airplanes. In cruise, most of an airplane’s energy is spent overcoming air resistance to move forward through the air mass (parasitic drag) rather than to create lift (induced drag).
