Replication and Experimental Characterization of the Wallace Dynamic Force Field Generator

In the 1970s, Henry W. Wallace filed a number of patents claiming that the rotation of masses with a net nuclear spin leads to the generation of a gravity-like force field that effects other rotating masses as well as heat conductivity. Based on his patent drawings we designed an experimental apparatus as close as possible to his original design including features to mount precision laser sensors to record speed and orientation of the rotating masses. It consists of a generator and a detector assembly with rotating masses as well as a massive top and bottom part of the same spin-polarizable material in order to provide an effective pathway for the claimed field. We chose brass with about 60% of Copper that is spin-polarizable. The assembly weights around 150 kg. Both assemblies can be rotated using compressed air up to 28,000 RPM as in the Wallace patents. Wallace claimed that the oscillation period of the rotating detector mass, oscillating around a knife-edge support along its middle-axis, varies with the orientation of the generator assembly. This could be explained by either magnetic or indeed anomalously large frame-dragging fields. Therefore, in addition to the detector assembly, we implemented magnetic field sensors, accelerometers as well as a highperformance laser-gyroscope in order to investigate possible magnetic influence and direct gravitational and frame-dragging signals. Here we report on the construction as well the results of our measurement campaign with, up to our knowledge, the first replication of the Wallace dynamic force field generator. We did find an anomaly in the oscillation of the detector gyroscope similar to the claim of Wallace, but we could trace it back to a vibration artefact.
