Got some new news. Looks like you were right James; on all counts. It's basically a little gyro that uses the weight at the edges of the fan (magnets) to resist movement off it's plane of operation. Also, they do actually have small ball bearings at the center hub. Although the TMD fans got an excellent review and technical description in the following URL: http://www.dansdata.com/tmdfan.htm , I'm still peeved that they used the term "bearingless".
