Why aren’t there Battery Powered Airplanes?


A 200-seat airplane weighs about 115 tons at take off.

About a third, or 38 tons of that weight is the kerosene fuel.

The other 77 tons are the passengers, their luggage, and the airplane itself.

An electric, battery-powered airplane would require nearly 3,000 tons of lithium-ion batteries – the batteries would weigh 39 times more than the plane, passengers, and their luggage.

Nor would fuel cells do much better.
