These things are so darn cool I think one of these is in my future projects for sure.

Each side has a solar panel which causes it's coil to jucie and repel, thus it spins,
while levitating, no worry for bearings there, but what if I attached a Faraday Disc
in N-Machine fashion, then I can turn the disc for free all day long, and no bearings.
wait a minute, I sure don't want that thing getting away, at 3000 RPM
Hmmmmm? Regardless I see something here.
What if collector coils are near the Mendocino? Picking up any flung fields?
I wouldn't categorize this has having no bearings. The outside magnets have a force on the pen and is pushing and holding it inside the tiny hole. When the system rotates then the pen is rotating inside this hole which causes friction just like a normal bearing would.
Here's a true levitating homopolar motor with no bearings, http://www.youtube.com/watch?v=2hHfkK4iGBQ

True but a magnet on each end of the rod
with stationary fixed mounted opposing mags facing them,
would hold the whole thing in place and eliminate pen, no?
The one you showed me isn't powered by light, but a larger
model could be, then put it in a vaccuum so there's no drag.
invent a lazer brush, and it would spin for ever.
In any case if these were all round or cylinder shaped, using
those flaxable solar panels, they would have much less wind
drag, even without a vaccuum.
Very cool.
Would make a very effective display piece.
