Abstract: A concentrated solar power generation system includes a movable platform having a groove, a Fresnel lens located in the groove of the movable platform, a header located below the Fresnel lens, a plurality of heat collection tubes arranged in a circular array, a reflector with a tapered surface, and a support base. The header has a water circulation pipe, an inlet pipe and an outlet pipe. The inlet pipe and the outlet pipe each are communicated to the water circulation pipe. A lower end of each of the heat collection tubes is fixed on the support seat, and an upper end of each of the heat collection tubes contacts the water circulation pipe. The reflector is mounted on the support base and located in a space enclosed by the heat collection tubes.

Abstract: A kit for carrying and storage of a toothbrush, toothpaste and associated materials and tools for dental hygiene wherein the quantity of dentifrice included is selected to be exhausted simultaneously with the end of life of the enclosed toothbrush, thus urging the replacement of the toothbrush at the proper time. The enclosed toothpaste reservoir has a small quantity of differentiated paste at the bottom which when ultimately dispensed, indicates imminent exhaustion of supply. Marker flags of color or other sensible characteristics for toothpaste and other materials are proposed.
