I recently saw a fascinating article on BBC science news about researchers at St Andrews University who have suspended a microsphere on a laser beam in a vacuum and used the polarised laser light and lack of friction to spin the microsphere up to 600 million rpm (the article is here, & the paper was published in Nature Communications).
I've been looking for a way to test MiHsC and have been wondering about spinning discs, but this is a far better method since the accelerations can be larger and the effect of MiHsC is then more detectable. Using the same calculations that I used to predict the Tajmar effect here and the Podkletnov effect here, I predict that when you spin a sphere of radius 2.2x10^-6 m at more than 195 million rpm the increase of inertial mass from MiHsC should be enough to get it to move upwards against gravity.
In the BBC article (in the analysis side text) it says that at about 600 million rpm the microsphere mysteriously 'dissapeared'. Interesting, but first it is necessary to check whether this dissapearence was due to the microsphere exploding under centrifugal forces or doing something else that physics already predicts. I've emailed the people in St Andrews, so hopefully they can have a closer look.
I stay tuned. :-)
I'm following Podkletnov experiment since a bit.
I read he also founded a site looking for sponsors (he even asked ME if I could sponsor him! :-) )
I even bought a fast-rotating drill (30.000 rpm) and a superconductor disk to test... but drill&disk "disappeared" flying to me neighbour's garden befor reaching 30.000 rpms!! LOL
That's the true scientific spirit: trying the experiment yourself.
