This is so fundamentally amazingly marvellous that i don't believe a bit of it :-) ie things that look set to transform reality as we know it once we learn how to scale them up a few million times usually turn out to not exist :-(. But we can hope. > They apparently measured > a force of 0.0001 Gee's at 6500RPM, so assuming that > the spinrate is directly proportional to the effect, > they would need 65 million RPM to levitate an object > over the spinning disk.. :) A mere matter of engineering :-). If a million mechanical revs per second is what it takes to generate essentially antigravity then a million mechanical rps you shall have by next year some time. Small OTS turbines are good for 100,000++ RPM so they're a few tenths of a % of the way there already :-). Also, if effect is not size limited one can imagine some extremely small devices happening.
