Pulsed Motor Technology

The Investigation of Ultra-Efficient Pulsed Motor Technology
Joshua Jones, 14, Titusville, Fla.
Military Channel Army/Navy Award, Discovery Channel Young Scientist Challenge, 2005

Project background: Joshua was interested in power generation and wanted to investigate using pulsed-motor technology to drive a generator apparatus as efficiently as possible. He hypothesized that his goal to achieve "unity" or "over-unity" energy conversion would be impossible given losses due to friction, gravity, and heat.

Tactics and results: Joshua built a two-coil impulse motor based on a design he found during his research. He added a third coil to recapture some of the kinetic energy of the rotor and feed it back into a battery. He ran tests under different conditions, collecting the data on his laptop so that he could maximize the output and efficiency of the unit.

Joshua was able to attain only 22% efficiency, but he discovered a resonant-frequency hum during a stopped-rotor situation that increased output with little change in input. He hopes to explore this further in his next project.
