RobotFK comments on ‘Very real’: Expert says electric flights are closer than we think

Lol. Current batteries sit at 250WH/Kg even with Solid state Batteries at 500WH/Kg this is still way of to Kerosene at 11.000WH/kg energy density. Even short flights will be rough with most of the plane being filled with batteries out of necessity

Transporting the "fuel"... Aircraft is the last place we should be putting battery tech - today.

Even cars aren't very good because most of the energy is for moving the vehicle, not the passengers (an existing problem for fuels, but current fuels as noted have a much higher weight-to-energy ratio). And with planes you're transporting less fuel weight as you fly.

Bicycles and motorcycles (or scooters) are the best bang-for-kilowatt right now. We should be promoting those and increasing experience/expertise there.

Even terrestrial trucks make far more sense than aircraft, currently.
