Normally a Bedini-Cole window motor uses a sensitive hall sensor circuit that is easily damaged by high voltage. Here we have a very low-tech mechanical commutator that is more resilient.
Combination of solid state radiant charger, powering a microwave capacitor, which is powering a Bedini-Cole window motor with mechanical commutator. This setup allows for very high voltage input, with low current. While this replication doesn't match the voltage level of the Edwin Gray designs, it is similar in principle. The radiant charger produces static electricity, and the static electricity is stored in the capacitor which then discharges it into the electric motor. The capacitor has upwards of 200-400 volts in it while performing this video, and this level of voltage would instantly ruin a small reed switch or a hall sensor circuit. While crude, the mechanical commutator design does allow more flexibility, and is probably why Lutec Australia uses mechanical switching on many of the motors in their videos.
