This strikes me as rather odd:
Tests of Mach's Principle with a Mechanical Oscillator*

James F. Woodward has made a prediction, based on Sciama's formulation of
Mach's Principle in
the framework of general relativity, that in the presence of energy flow
the inertial mass of an
object may undergo sizable variations, changing as the 2nd time derivative
of the energy. We
describe an attempt to observe the predicted effect for a charging
capacitor, using a technique that
does not require a reactionless force or any local violation of Newton's
3rd law of motion. We
attempt to observe the effect of the mass variation on a driven harmonic
oscillator with the
charging capacitor as the oscillating mass. Positive and negative phase
shifts in the oscillator
motion with respect to the driving force are predicted to result from
inertial mass variations. The phase shift is constant, so that data may be
accumulated over a very
large number of oscillation cycles to insure high precision in the phase
shift determination. We
report on the predicted effect and the design and implementation of the
At this time, however, we will not report on observations of the presence
or absence of the

Oh. Too bad.
Anyone know of more recent reports from Cramer, et al?
