NOVELTY - The system (200) has a heat engine for storing content at predetermined temperature. Fans deliver air flow through the heat engine. A cryogenic storage unit stores cryogen and includes insulated pipes thermally coupled to the heat engine to cool the heat engine. Reuse pipes are coupled to the insulated pipes to send a portion of cryogen gas flow back to the cryogenic storage for reuse. A controller maintains the predetermined temperature. An on-board power generator supplies operating power to the controller and the fans.    USE - Cryogenic system for use with a lorry or reefer for removing energy to remove environmental pollutants and undesirable usage issues.    ADVANTAGE - The system achieves elimination of exhaust gases from diesel fueled payloads to safely kept cool at large distribution centers, thus eliminating localized high pollution and aiding in processing of products through a terminal while reducing over-time and employee stress from commuting to a remote location. The system uses the sterling engine as a direct supply of electrical power, so that minimum components are required, thus achieving uptime improvement for cryogenic process while allowing process to operate in a self-sustaining fashion. The system ensures creation of electrical power by using available cryogens from process bulk supply to generate required electrical service for allowing process to continue regardless of external factors or conditions dependent on availability of inherent cryogen. The system utilizes a heat exchanger of an engine to be sized appropriately to supply required heat transfer rates, thus producing appropriate mechanical action to produce needed electrical current from an alternator.    DETAILED DESCRIPTION - The power generator is a turbine or sterling engine.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a lorry or reefer with a cryogenic electrical generator.
