Hmmmm - that's interesting, Sauron...
The levitating object in the photo is a model of toy called a Levitron. It uses a small spinning magnet floating above a larger base magnet. There
are several versions available. I have a few myself. Saw it first in the old OMNI mag about 15 yrs ago.
A more recent 'deluxe' model has a chromed top like in the picture.
www.levitron.com. Once you get it spinning and floating above the
base you can do neat tricks like slide a drinking glass around it, cup it in your hands, or make it appear as if it is floating between your fingers
(as in the photo above).
As for the Casimir force the article refers to: Well, maybe. Once we can see an actual prototype of the technology in a working model, that would
indeed be something to get excited about. IMO, it's a bit disingenuous to talk about floating levitation technology but actually show a picture not
of the technology discussed but rather of a regular production toy available on the market (eBay search for "levitron" to get one for yourself to
play with...
Otherwise - intrigued by the possibilities, that's for sure!
