Is battery energy more efficient with air speed lift from a wing, like traditional aircraft, or from air suspension, like a helicopter? Does the mass/energy of a gasoline power train (including fuel & motor) exceed an electric power train?
I guess I'm wondering about the viability of electric power for flight at all. Drones are useful for some applications with light payloads and conducive environments, but when you need to lift a substantial payload, like me, isn't battery just too little power density?
