As noted elsewhere in this thread: probably ain't gonna happen. Battery energy density increases are tapering off. We may already be close to the maximum possible (where close means within a factor of 2 or so).
- walrus01 1mo agoI feel inclined to agree with this based on my observation of batteries that can actually be purchased (not hype PR things where people announce a miracle 450Wh/kg batttery). The electric VTOL companies in this niche that survive may ultimately end up with something like a small series hybrid that uses Jet-A fuel and has a single gas turbine engine driving a generator, along with batteries, and electric propulsion motors. Electric motors and gas turbine in use to lift off, consistent lower fuel consumption gas turbine -> electrical use during level cruise flight, then another burst of amperage and use of batteries during the landing phase.
