I wondered if such a thing existed, because I'm sure it does, and it does.
Seems like this could be the sort of thing money should be put into to deal with those awful airline emissions.
Could they be stuck on existing planes to save waste or would being a 'Boeing' of an idea?

One of many ways of dealing with emissions of course, trashing the private jets of the elite is also an option. 🐋

Electrified Aircraft Propulsion (EAP) | Glenn Research Center | NASA

Overview From air taxis to subsonic transports, EAP will benefit the U.S. economy, the environment, and the flying public. These planes will be quieter, Electrified Aircraft Propulsion (EAP) is the use of propulsors (propellers or fans) driven by electric motors to propel aircraft, air taxies, or a wide range of other flying craft. NASA is developing technology, aircraft concepts, test aircraft, & ground test facilities to turn this idea from science fiction to reality.

@Lazarou Batteries are very heavy. That NASA is working on a program that might do somewhat better doesn't make this any sort of practical plan in the next decade or two.

Heavier-than-air flight in industrial quantities is incompatible with a future for our ecosystem; exponentially increasing consumption is not sustainable on a finite planet.
