Tesla Dry Electrode Batteries Will Enable Large Passenger Electric Planes
Israeli startup Eviation is making a nine-passenger all-electric regional passenger aircraft by 2021. It will take 9 passengers up to 650 miles at a cruise speed of 240 knots.
Alice uses distributed propulsion with one main pusher propeller at the tail and two pusher propellers at the wingtips to reduce drag, create redundancy, and improve efficiency.
Alice will cost at least four times less per passenger-mile and it can also operate as a drone to transport cargo or to reposition the plane for its next scheduled flight.
Vastly improved batteries could enable all-electric passenger planes for 50-200 passengers and longer ranges. There are many companies working on electric passenger planes.
Tesla completed the purchase of Maxwell Technologies which will give Tesla higher energy density batteries, lower costs for batteries, double battery life and will allow battery factories to have 16 times the production in the same space.
