One aspect of the present invention relates to a new alternative to the Bayer pattern for spatial subsampling in color imaging applications. By \u201ccontent aggregation\u201d, it is meant the procedure by which applications are introduced by a content provider, and are then aggregated into a service for provision by that content provider andor service provider. As a result, in the coating material, the enlargement of the crystal grain of the conductors is significantly restricted, whereby conductive end rings are connected to the core andor the conductive bars. Due to the temperature differential between the hot and cold sides of the thermoelectric modules, the modules produce electricity to power the pump circulating the fluid through the conduit loop.
