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.
