One link I forgot to give is the home for the California Institute for
Physics and Astrophysics. http://www.calphysics.org/
The "About CIPA" page says:
------------------------------
The California Institute for Physics and Astrophysics is a
privately-funded, academically-oriented research center dedicated to
exploring fundamental problems in physics (e.g. gravitation, inertia, the
nature of mass) as well as very-long range technological possibilities
that may emerge from the properties of the quantum vacuum.
------------------------------
But where this private funding comes from is not readily available.
