Ion drives should have neutralizers

[Erik Olesen]

I have noticed that none of the Ion drives that I have seen so far such as the stock "Dawn" or any of the ones from mods like Near Future Propulsion have neutralizers on them. In real life these are essential to the functionality as they ensure that the exhaust gases don't re-enter the engine, canceling out the thrust provided.

Modeling-wise it would be easy to implement - just stick a tube on top of the engine that also glows as the engine fires. See pictures

This is a very small point but still I think it would add to the realism, which I believe to very much a core value of this game

Well, since there is no such thing in KSP like cancelling thrust because of re-entering gases back to the engine, it would be useless.

The point isn't usefulness, it's aesthetics. While it's small change, it would on be noticed by a small number of people. While it's technically an inaccuracy, I don't feel it would be worth PorkJet's or somebody elses time to update the model.
