The Podkletnov (1992), Tajmar (2009) and Poher (2011) experiments all have a common theme that is consistent with MiHsC: in all three a sudden acceleration of masses in the vicinity of an object, causes that object to accelerate unexpectedly. In the Podkletnov case, the sudden vibrational acceleration of a superconducting disc caused a test mass to be less sensitive to the Earth's gravity, and lose weight, as if it has gained inertial mass (for the vibrational case only, MiHsC predicts 50% of this apparent weight loss). In the case of Tajmar, the sudden rotational acceleration of a metal ring caused an accelerometer near the ring to very slightly move with the ring, as if it had gained inertial mass and had then to move with the ring to conserve the momentum of the system (MiHsC predicts this case exactly, see McCulloch, 2011). In Poher's experiment, electrons were accelerated to huge speeds in a superconductor and then rapidly decelerated as they hit a non-superconducting layer. This caused a 'jump' in a nearby shielded accelerometer.
As far as the data allows, MiHsC is consistent with all three experiments, since it suggests that when an object suddenly sees nearby accelerations, the Unruh waves that are assumed to cause its inertial mass become shorter, and more of them fit within the Hubble scale, so the inertial mass increases in a new way, and to conserve momentum, anomalous motions occur. The Podkletnov and Poher experiments generate huge electron accelerations which allows the easier detection of the anomalous motion, but the problem is that the accelerations involved cannot be accurately quantified. For example, in the Poher experiment the electron acceleration is said to be "greater than 10^15 ms^-2" but cannot be pinned down to a specific acceleration that I can plug into MiHsC to test it. In contrast, the Tajmar experiment produces acceleration from a ring rotation so it is quantifiable, but the acceleration is tiny (2.5 ms^-2) so the anomalous motion is difficult to detect above noise.
The best way to easily and unambiguously test MiHsC would be to reproduce the huge accelerations of Podkletnov and Poher but make them quantifiable as in the Tajmar experiment. Any practical suggestions would be welcome!
