Electric Airplane Propulsion Mechanism

Daniels: How do you even get propulsion in an electric airplane? And then, of course, lots of good stuff about batteries. So why can't we just a plane into a battery, make a big old battery and get it going? He says taking off from the ground into the air is similar to accelerating a rocket or lifting a rocket up into the air. Daniels: The real issue with an airplane is that airplanes need a lot of power ecause you need to move forward to get that lift over the wings.
