I've always wondered why an electric motor can't run a generator that was powerful enough to run the electric motor. I've done some reading up on it and depending what website you read, there is and there isn't --- It would seem to me to be the next step for electric motor development.

Largely because you'd be breaking the Law of Conservation of Energy; Energy in = Energy out (Curse you, Physics! :icon_twisted:)

The system you describe, even with theoretical zero-energy-loss wires & absolutely friction-less generator & motors, will only give out the same power as put in from the original source (batteries, solar panels, nuclear power station, etc.).

More to the point, having said arrangement do anything useful - such as running a propeller or a set of wheels - generates a massive drain on the system thus accelerating the drain.  As said above, even if a theoretically perfect arrangement such as that described were possible, it would do nothing useful.

Beware the internet.  Just because someone has the ability to publish something on line is no guarantee that they know what they are talking about.

Don't I know it already ---

Most of the images I looked at which show an electric motor hook up to an alternator were just straight 1 on 1. I was thinking why can't it run through a gearbox so it could power two alternators/dynamos. There was some images of an electric auto gearbox I saw which had two electric motors with one output shaft. Reverse what it does by attaching an electric motor to the output shaft and change the two electric motors to dynamos --

Electricity stored in lithium-ion batteries in the fuselage that provide enough energy to fly about 160 kilometres (100 miles) on a single charge. There are also plans to update the batteries in the future so as to increase the range.

Thanks Greg. I presume that those Li-ion batteries replace the lower fuselage fuel tanks?

Err...no.  It is a MagniX one.  I just clicked on it again to confirm.

Hmm! I've just reclicked on your link and now it's showing a video about a Russian fighter, Su-27 or a variant. Can't tell because it's a Russian video all in Russian (and I don't speak Russian very well ---  ;D )

edit; Just clicked on it again and it's gone back to the F-35 one I saw earlier ---

It works no problem for me - just tried again.

Either way, if you search for "magniX @ the 2019 Paris Air Show" on youtube you should find it.

It worked fine for me, no problem.  A very interesting concept that bears watching.

Had another try and saw the problem, At the beginning for about a blink of the eye, it starts with the electric motor video, but jumps to the next video in the list. If I click on the back button it goes to the electric motor video. Not sure why it's jumping like that.
