Aaron Murakami Plasma Ignition

Aaron Murakami

A simplified plasma ignition system for internal combustion engines that uses high-energy plasma ionization at the spark plug gap for more complete combustion. Claimed to achieve significantly better fuel efficiency with some engines reportedly running on 'fumes'. Documented in the 'Ignition Secrets' books and video presentations.

Babcock/Murray SERPS

Jim Murray & Paul Babcock

A Switched Energy Resonant Power Supply demonstrated at the 2014 Energy Science & Technology Conference. Uses a power transformer to run loads while storing energy in capacitors, which discharge back through the load to neutralize the load seen by the power supply. Babcock's 5-nanosecond ultra-fast switching is the key innovation. Live demo powered 50W incandescent bulbs while drawing approximately 1 watt from source.

Don Smith Magnetic Resonance System

Donald Lee Smith

High-frequency, high-voltage resonant systems using Tesla coils, neon sign transformers, spark gaps, and specialized coil configurations. Smith claimed power output scales with the square of voltage times the square of frequency (P ∝ V² × f²). Multiple designs described in his lectures and documents, all based on converting 'ambient magnetic radiation' into usable electrical power.
