Electric Planes and Drones

Aviation is where lithium-ion runs out of road. Jet fuel carries roughly forty times the usable energy per kilogram of a good battery cell, which is why electric flight is currently confined to short hops, trainers and drones.

That ratio is the right lens for eVTOL announcements too: the questions worth asking are payload and reserve, not headline range. We cover the projects that publish real numbers, and we say plainly when a demonstration flight is a demonstration rather than a product.
