...another example are the pancake-motors in harddisk drives, ie: "rotational" stepper motors.

Suppose you wanted to use the wheel-is-the-motor idea on, say, a bicycle wheel: How hard and expensive would it be to add magnets to the bike spokes, and windings to the frame or fork? How hard to manage the throttle?

Otto -- Google 'MIT wheel' It turns out the way to control something inside a spinning bike wheel is through Wi-Fi.

Just saw an article about this on Yahoo today: The Kit That Turns Any Car Into A Hybrid | This Could Be Big - Yahoo! News
Seems pretty cool, but like it's been said already, I don't see how $3K would cover all the necessary components.

You need about an inch of clearance from the outer diameter of the caliper to the inner radius of the wheel to fit the rotor in and convert this to a plug-in hybrid.

I would have to redo or delete my rear wheel skirts, poor me, .

Hmmmm, that sounds dangerous in a car. Hackers could break into the wifi connection and mess with it. If feasible then the wheel would need to make "failsafe choices" on how to behave as a function of sensors that are independent of the wifi commands.

Nope, just plain IDEOTIC. A couple wires are NOT that hard to do.

So, not an acronym then? It's MIT's idea not mine. I'd use Bluetooth.

I know what you mean, but I can understand that it's "saveiotic" in the sense that no wiring = lower cost in exchange for higher risk, aka you only have to concentrate on the wheel-well of the car for now and the interweb of bad guys later.
