Title: Podkletnov machine
Post by: Mr Andrew on 17/09/2007 02:26:45
Ok, I'm not sure if this was already in another thread (or even if I've posted in that thread...) but here it goes:  How does the Podkletnov machine work?  Supposedly the machine consisted of spinning superconductors and it generated a gravity-shielding effect (the actual empirical result of running the machine was a significant drop in air pressure above the spinning superconductor).  From the thread on SR and magnetism, I understand current running through this superconductor might generate a large magnetic field, thus displacing some of the air pressure but this is not the explaination I've heard.  Using the same reasoning as the SR approach to magnetism, shouldn't a spinning mass actually generate an attractive gravito-magnetic field which would increase the air pressure?  Can someone please explain this to me?

If we give any credence to the idea that gravity is mediated by Gravitons it shows how unlikely that gravity could be shielded.
The suggested mass for the Graviton is about 10^-11 that of the Neutrino, to stop Neutrinos would require light years of lead how about stopping Gravitons !!
