Null result for Cahill's 3-space gravitational wave experiment with Zener diode detectors

Zener diode detectors have been reported to show correlated current output related to the absolute motion of the earth through space [1-4]. Such reports are of utmost importance since it would contradict the Michelson-Morely experiments, the basis of Special Relativity, and connect the randomness of quantum theory with gravitation. Experiments designed to reproduce the reported effects have not seen the reported wave form output or any correlation between Zener diode detectors. Instead we found no detectable signal could be discerned above the noise floor of the digital storage scopes themselves. This does not mean the Cahill's space flow effect does not exist, however the methods reported in the literature do not describe equipment that reproduced the reported measurements.
