Abstract
This power source is created by the motors of an electric vehicle, such as a subway train, because when being braked, its motors become generators, and the current created may be used to heat and pump hot and cold water into tall building structures. Primarily, the power source includes an additional circuit in the vehicle, for take-off of the generated current to a motor driven compressor and an electrically heated boiler. The system also includes a compressed air tank, a group of hot water tanks, and a group of cold water tanks.
