Inflight Restart without starter power ?

Some channels i watch are a bit of a acquired taste. No need to explain further really. But anyways...

AgentJayZ again kills it with a very interesting video for all tech and physics nerds out there.

Can you restart a turbine, turbojet or turbofan (most likely) engine without any auxiliary power besides onboard batteries and maybe a bit of electricity from the Ram Air Turbine which bigger jets use in case of a emergency?

**spoilers start here**

What does that mean? Imagine, you're in a jet somehow. And not only both engines quit, but you're actually unable to start the APU (Auxillary Power Unit, it's own tiny turbine-generator). So you got no real options left but use the windmilling of your turbine to get it up to speeds where you can inject fuel and actually start it.

Tl;dr: This scenario is _EXTREMELY_ unlikely, just on the grounds that usually no engine quits for no reason.. But if you are there.

Well, it's not good ..... but _might_ just be possible.... Most probably killing the engine along the way. (You will necessarily overheat it in the process and shorten it's lifetime massively. ;))

O.k. sorry, enough technobabble.
