Warp Drive Symposium - London

If you can make it, this symposium at the British Interplanetary Society in November looks interesting. Not many confirmed speakers as yet, though. For those of you unable to make it, the following links to work by the known speakers may be of interest:

Remo Garattini:
Spacetime Foam and Vacuum Energy [PDF]
The Cosmological Constant as an Eigenvalue of a Sturm-Liouville problem and its renormalization [PPT]

Claudio Maccone:
Levi-Civita Effect in the polarizable vacuum (PV) representation of general relativity [PDF]

Unfortunately I couldn't find any references to the work of Jeremy Gardiner. If you know of any, let me know & I'll add it to the list!

Reversing the Casimir Effect

News on this development at St Andrews University, using metamaterials with negative refractive indices, first appeared last month, but there's now also a quite entertaining page explaining the principles for a general readership.

Useful Amounts of Photon Propulsion?

Just noticed this, apparently the first photon propulsion system to produce practical, useful amounts of force.
