I must have been sleeping, but it appears I missed the emergence of another Fleischman-Pons ("cold fusion") style episode, this time having to do with antigravity. Experiments in 1992 in Finland seemed to show that the Earth's gravity could be shielded with a superconductor. This experiment, by Eugene Podkletnov, at Finland's Tampere University of Technology, apparently displayed a reduction in the weight of objects placed above a levitating, rotating high Tc superconducting disk, exposed to high frequency magnetic fields. http://www.virtualpet.com/rbbi/folders/tech/basic/gravity.htm http://www.inetarena.com/~noetic/pls/gravity.html#pandb There are at least three different theoretical models for the effect -- gravitomagnetism, local change to cosmological constant, and outright shielding. Detractors have pointed to possible experimental errors as the cause for the apparent levitation. Gravitomagnetism The coupling of supercurrents to the classical gravitational field is extremely weak. The reason, of course, stems from the smallness of the coupling between gravity and the energy-momentum tensor of matter. One might wonder whether in a quantum theory of gravity - or at least in an approximation of the theory for weak fields - the Bose condensate of the Cooper pairs, due to its macroscopic quantum character, can play a more subtle role than as a simple contribution to the energy-momentum tensor. In other words, we wonder if the macroscopic quantum coherence of the condensate can be taken into account at a fundamental level in computing the interaction between the superconductor and the external gravitational field. Results might then differ from those obtained for the gravitational coupling of "regular", incoherent matter. Shielding It appears that a theory is being developed for simple shielding of gravity, in analogy with the shielding of microwaves by metal. Different materials shield or don't shield EM ratiation at various frequencies; metal shields microwaves, but plastic does not. Pure YBCO superconductors do not shield microwaves, but YBCO doped with small amounts of lead or silver does. They relate this to gravity shielding by virtue of two ideas -- that gravity might have a frequency (very high, on the order of the Planck length, or 10^34) -- a very speculative idea -- and that the bose condensate within a superconductor could radically lower the effective interaction frequency of gravity so that it could be shielded by ordinary matter. On a related note, NASA has Breakthrough Propusion page http://www.lerc.nasa.gov/WWW/bpp which outlines their plans and activities to explore (and hopefully perfect) non-mass based propusion technologies. They seem to be taking this seriously enough to form a Delta-G group at their Marshall Space Flight Center to try and reproduce Podkletnov's (and others) experiments. --Steve PGP mail preferred, see http://www.pgp.com and http://web.mit.edu/network/pgp.html RSA fingerprint: FE90 1A95 9DEA 8D61 812E CCA9 A44A FBA9 RSA key: http://keys.pgp.com:11371/pks/lookup?op=index&search=0x55C78B0D --------------------------------------------------------------------- Steve Schear | tel: (702) 658-2654 CEO | fax: (702) 658-2673 Lammar Laboratories | 7075 West Gowan Road | Suite 2148 | Las Vegas, NV 89129 | Internet: schear@lvdi.net ---------------------------------------------------------------------

Don't feel bad about not hearing about it....I only heard about it from some friends this past summer. My first reaction was "say what?" After looking at a summary of news reports, I was less than enthusiastically interested any more. (My hunch: eddy current effects) An effect this important, requiring so little equipment, is confirmable in a matter of days or weeks. That this report has been floating around--pun intended--for more than several years, tells us somthing important. Wake me up if it's actually confirmed. But don't wake me up just to tell me the claims have been withdrawn. --Tim May The Feds have shown their hand: they want a ban on domestic cryptography ---------:---------:---------:---------:---------:---------:---------:---- Timothy C.

I am tired of the constant, snide implications on the CypherPunks list that the government might be holding something back from the American citizens. Just because the announcement of startling new breakthroughs in such things as 'cold fusion' and the like quickly turn into 'cold silence' and denials is no reason to think that those in power are using the latest developments in technology to increase their hold on society, instead of using it for the benefit of all of mankind (and the 'broads', too). Some asshole on the list (it might have been me, before my 90 days in solitary confinement in a cell next to Jim Bell) even went so far as to suggest that if the secret government laboratories were releasing details of a new radar that could track movements of people through stone walls, etc., that they might have even more startling technology at their fingertips. What a crock! To suggest that people who are willing to sacrifice their own integrity and moral values in order to assassinate others for our benefit would then turn around and subject their own citizens to the same self-serving, arbitrary atrocities is nothing more than the ranting of anarchistic lunatics. [LUNATICS! DON'T _USE_ THAT WORD! I DON'T _LIKE_ THAT WORD! IT MAKES ME WANT TO.....AAARRRGGGHHHHH!] Thank you, I'm feeling much better, now... TruthMonger

Attila, Nice try, but few are likely to believe the obvious lies of an anti-social psychopath who tore a page out of a phone book at a public telephone booth in southern Utah on Jan. 3rd, 1997. Neither are the Cypherpunks list members likely to listen to the ludicrous claims made by Tim May (who wipes his ass with his left hand), Willam Geiger III (who has an unmatched blue sock in his bottom, right-hand dresser drawer), or Dimitri Vulis, whose name I have thrown into the mix merely to denigrate the reputations of the others by guilt through association. The SWAT team piling into the armored vans at this very moment *love* this list! SpookMasterMonger
