Plugin-less electric impeller

[spiritplumber]

This is too small for jet engines to profit from in oxygen-less atmospheres, and works reliably. Quadcopters can be made (and run out of batteries about as fast as real quadcopters do). You can get a motor glider going with 6-7 of these. Uses stock models, so it's friendly on memory too.

A very nice addition, but the problem here is most people will take one look at this and go "Neat. Code. What the hell am I supposed to do with this?"

It's much more polite if you package it for people.

You can use this to simply run a standard jet engine in any atmosphere, since it doesn't use a custom named intake air resource. It takes any atmosphere and makes it into jet engine breathable intake air.

Might I suggest adding a new resource definition to the bottom of the code? Define a similar resource with the same density, then use the same air intake module to create the new resource and switch the fuel type in the engine module to use the new one as well. This will stop people from simply stacking up 20 of these 1kg O2-less intakes onto a ship and using a turbojet engine on Duna or Eve

That's about as cheaty as stacking 20 ram air intakes on one jet to build a SSTO without putting in effort... I wanted to provide a single-file solution The intake area is so tiny that you'd need a lot more than 20 of these to run a jet. However, I will now try to do so, since you mentioned it

Tomato, true that. I would like this to go in the ReStock parts pack since it uses existing polygons, but trying to contact the ReStock author failed.

You need about 50 to run the jet engine appreciably... Again, note the tiny numbers. You could also use KIntakeAir instad of IntakeAir if you have kethane installed. The idea, as with my multiplayer "mod", was to do everything in 1 human-readable file...
