Contrary to normal Lasers, BEL utilizes an organic dye/polymer system, which is arranged between two mirrors forming an optical micro-cavity. The incoming light is multiple reflected between the mirrors, giving rise to an effective photon mass and a confining potential for the Bose-Einstein condensa.....

The novel braking resistor consists of a power electronic circuit, with which the braking energy can be fed back to a three-phase system. The recovery of braking energy can thus save energy, reduce costs and relieve the burden on the environment.
