An airline and EV startup to bring electric airplanes for short haul trips
U.S.-based startup Wright Electric and British budget airline Easy-jet have announced a partnership to build electric airplanes. The goal is for the all-electric plane to be capable of ferrying 150 people on flights under 300 miles.

Hard to imagine the battery power required to do this.
This has to be many years away.

I could see using battery to get the plane in the air but once it's up there as long as air moves around the craft I don't see how we can't harness that energy. I know perpetual motion but still...like in cars. Why isn't there a generator wrapped around the drive shaft and all four tires. Seems wasted energy to me.
That's just my opinion and it has no value.

Zunum Aero is looking at a hybrid design that would reduce noise and increase efficiency significantly. It would have a turbine for charging the batteries, and they're looking at 700 miles for the range.

“The energy density for batteries isn’t high enough to even get a couple of people off the ground, let alone 30 or 40,” says aviation analyst Richard Aboulafia. And if the hybridization scheme isn’t as efficient as engineers hope, it could require just as much fuel as a conventional jet engine or turboprop—in a much newer, less proven, system.

Of the energy output of fuel in a car engine, 33% is spent in exhaust, 29% in cooling and 38% in mechanical energy, of which friction losses account for 33% and air resistance for 5%. ... With current technology, only 21.5% of the energy output of the fuel is used to actually move the car; the rest is wasted
