From The Engineer:
A research team at the Department of Electronic Engineering, City University of Hong Kong (CityU), has developed an energy-efficient burn-in system for power supplies that "reuses" electricity.
The system is expected to lower production costs for power supply manufacturers and save energy.
Electronic appliances like notebook computers and chargers for cell phones need a power supply to convert alternate current (AC) from the socket into direct current (DC). But before a power supply goes to the market, it has to go through the process of "burn-in", a process which wastes a large amount of electricity.
