Press Electric aviation has long held great promise, but viable designs have been elusive. The biggest reason? Battery weight. Because so much energy is required to get an airplane off the ground and keep it in the air, a really big battery is needed – big enough that with current technology, it would be too heavy to make the plane usable.
“You can’t just stick your Tesla battery and motor in a plane and expect it to work.” Combs says.
