A torsional pendulum consisting of a dome-shaped energy collector and a nylon monofilament support fiber was suspended above the cranium of a seated human subject and the effects of the subject on the oscillations of the pendulum were measured. There were dramatic effects, with FFT analysis of the oscillation signal showing many new frequencies in addition to the natural frequency of 0.034 Hz. The lowest new frequencies (0.0-0.002 Hz) were accompanied by a shift in the Center of Oscillation (COO) of the pendulum, and the higher frequencies were associated with changes in the amplitude of oscillation. The Delta COO (7.3 deg) and the amplitude (12 deg) effects were substantial, and would require forces equivalent to 34 and 56 mg, respectively. Residual effects on the Delta COO and amplitudes persisted for at least 30 min after the subject departed, and the rate at which they subsided conformed to the kinetics of a chemical relaxation process with a relaxation time of 600 sec. Shifts in the magnitude of the Delta COO with the subject present also conformed to chemical relaxations processes, with relaxation times of 35 and 200 sec. It is proposed that the energy that drives the anomalous oscillations when the subject is present is the result of enzyme-mediated energy transductions that convert metabolic energy into a form of energy that can affect the pendulum. Although highly speculative, it is suggested that aspects of quantum entanglement are involved in the energy transduction process.
