Query: Archimedes: a feasibility study of an experiment to weigh the
  electromagnetic vacuum   Archimedes is a feasibility study of a future experiment to ascertain the
interaction of vacuum fluctuations with gravity. The experiment should measure
the force that the earth's gravitational field exerts on a Casimir cavity by
using a small force detector. Here we analyse the main parameters of the
experiment and we present its conceptual scheme, which overcomes in principle
the most critical problems.
