| Sep 20, 2016 at 19:16 | comment | added | voretaq7 | This is really a physics question, not an aviation one: You're asking if you can build a perpetual motion machine (an aircraft that can indefinitely power itself), and the answer is no: A generator powered by the motor would require the motor to produce more power (to turn the generator in addition to the normal engine function), and combined with mechanical losses would ultimately reduce range because you're wasting power turning the generator. There is no such thing as free energy. | |
| Sep 20, 2016 at 15:01 | comment | added | RealAnswersNotAI | Could you be more specific and add more detail? Right now it's unclear what you mean by "an electric aircraft with a generator powered by the motor", which to me sounds like an attempt to have an electric power source power a motor, with the motor driving a generator to get free energy out of the system. Your question about "is there a way to generate enough power" is also unclear, since it sounds like you want to generate more electric power while on the plane, which would be a strange thing to do, mostly due to the difficulty in making it worth the weight. | |

Improved formatting, changed factually incorrect statement.

too broad question removed

| Sep 20, 2016 at 1:26 | comment | added | Nicholas | I mean a fairly small aircraft. Not much larger than a Cessna. It would use an Electric Ducted Fan design, so it almost would be replacing a jet, but still using a prop. | |
| Sep 20, 2016 at 1:21 | comment | added | egid | Your question is too broad. Electric aircraft exist at varying scales, but without a more focused question it's hard to say if it's "feasible". | |

I assume "electronic" really means "electric" here; please edit again if I'm wrong

| Sep 19, 2016 at 22:40 | comment | added | fooot | What kind of aircraft are your asking about? We have a question about large electric aircraft feasibility, and for replacing jet engines. | |
