you just are not going to get any useful energy transfer from the

We're no longer talking about the bling-bling pimp spinners, but
something that's weighted, possibly hidden inside the hubcap or
embedded in the wheel itself - you can still put the bling on
the outside.

No, let's do the pimp-bling spinney things. That would work in both
inertial (accel/decel mode) and steady-state freeway mode, from air
drag.

Yeah, the wind would make the pimp bling spinney thing work. But it
wouldn't DO any WORK.

Windmills do work, lots of work, and they're just powered by air.


When you hook it up to your compressor load, it
would fail miserably..

It would take only a tiny amount of power to pump a few cubic inches
of air a day. At thousands of strokes per day, its displacement would
be tiny... think about a piston the size of a pencil lead.

Then, there's that unsprung weight thingy again.
Nobody in their right mind would buy it, when my shock absorber version
would work much better.

Nobody would buy either one. But that doesn't make the ideas much less
interesting. You can never develop new stuff if you whack-a-mole every
idea as soon as it pops up.
