By "horrible ecological impact" I assume you mean battery production? Anything else? Central electrical power generation seems to be better and more efficient than individual ICE engines.With a full 7 minutes of flight time, and a horrific ecological impact on the planet, we are poised to leap into the future.
Sorry. Too much science in my background to drink this particular flavor of Kool-Aid.
It's not in service yet and might not be for some time. As far as I know, all they've done is the eight-minute test flight in December. One article I came across said that they were waiting for better batteries. That might take awhile. They're working through the complex certification process.https://www.flightglobal.com/airlin...ercial-aircraft-a-dhc-2-beaver/135711.article
DHC-2 Beaver on floats converted to electric power. It flies a 30 min commute and the plane has a 30 reserve.

Where did you find the 7 minutes of flight time stat? That seems quite impracticable.
Good information. I'll be able to use that.The 7 minutes? I made that up, but it appears I was pretty close. I'm sure the run-time for the engine is at least 20 minutes.
The ecological impact? Every aspect of lithium battery creation and disposal is super toxic, as is every aspect of the chip manufacturing for the computers and boards that control the motor.
I was part of the team that created sub-micron circuitry. When we were done, we had to dig hundreds of bore holes to test for pollution.
The site was so polluted that IBM immediately sold it to the town to get out from under any legal liability for creating the mess.
At the plant that actually makes the chips, the water is undrinkable for miles around the plant. IBM has to provide testing, water purification systems or replacement water for (nearly) every house in that area of town. It's slowly making it's way to the entire town.
Some of the byproducts are toxic in extremely small quantities. Exposure to arsine concentrations of 250 ppm is rapidly fatal: concentrations of 25–30 ppm are fatal for 30 min exposure, and concentrations of 10 ppm can be fatal at longer exposure times.Symptoms of poisoning appear after exposure to concentrations of 0.5 ppm.
Progress is wonderful. I'm merely pointing out that there is a cost and consequences for everything.
Gas turbines, thermodynamically, continues to be remarkably efficient, with a clean and well burning engine primarily spewing out CO2 and water in the exhaust.. surely that can't be worse than lithium production
Batteries don't store electrons. For every electron that leaves the negative terminal, another electron has to enter the positive terminal. Batteries propel electrons via chemical conversions within the battery, so you need chemicals that can propel vast quantities of electrons for long periods of time, but the whole thing has to be light, too. And the process has to be reversible so it can be recharged.....but there's only so many electrons you can pack into an anode.
Yup. On two tons of batteries. No room for people. https://www.seattletimes.com/busine...-electric-first-flight-of-a-cessna-turboprop/I read another article that this caravan had a range of about 100 miles.
