How about this?

This is "the thing you never want to see used."

it's a really big leap from wheel spinners to ram air turbines.

The wheel spinners would have an additional source of power,
namely angular acceleration. That alone would be enough to pump a
tire. So the momentum disk could be hidden behind a non-spinning
wheel cover.

Well, they also have inertia, and non-zero friction - I've seen
cars come to a stop, and the spinners continue to spin, in the
direction the car had just been going. But with the right gearing,
it wouldn't be hard to keep a tire up at all.

You're an idiot. A mere few grams of resistance and those things
fail
to function.


You just made that up. You sure didn't do the math!

No,he's right;those wheel spinners use low friction bearings,and any
crud will stop them.

So, you won't do the math either.

Math without practical experience is useless.

Practical experience without math is amateur guesswork.
