In 2001, John Christie and Lou Brits announced they had developed a self-running power supply that they thought they could bring to market within two years. Eleven years later, they seem to have disappeared. From the beginning, Robert Adams of New Zealand claimed they were simply using his designs and methods. The machine pictured below apparently worked, but when they tried to scale it up and use solid-state switching, they ran into endless problems. By 2008, they had gone back to brush commutation and were demonstrating a new machine. Then, there were rumors they sold out to a Singapore company. The LUTEC website finally came down last year.
