Subject:Re: Strange properties of superconducting meta-material - propellantless propulsion engine concept

Dear James

No, that's not what I have in mind at all - just the opposite.

I think nano-engineered high Tc metamaterial are very likely, and indeed, that's how the real ET spacecraft fly.

I could wrong of course.

Also, my point is LOW negative energy density interstitial EM fields - their bending effect on spacetime geometry is amplified by the fourth power of the dispersive index of refraction i.e. n^4G/c^4.

Jupiter mass stuff is not correct in my opinion. It it were ET craft would not be possible yet they are here - that's the scenario I am assuming in this war game.

i.e. Guv + (n^4G/c^4)Tuv(EM) = 0

n ~ -10^10

f(permitivity)E^2 +g(permeability)B^2 < 0

for non-radiative interstitial near induction fields (coherent states of virtual photons)

The high Tc metamaterial sounds unlikely. But the idea of negativeenergy interstitial EM fields of very high densities is interesting. :-)Seems the only way to do what you want to do given that assembling aJupiter mass of exotic matter any other way seems hopeless. . . .On Tue, 30 Mar 2010 23:32:54 -0700 JACK SARFATTI <This email address is being protected from spambots.
