An electromagnetic radiation collecting and directing apparatus is described herein. The electromagnetic radiation collecting and directing apparatus facilitates directing light from an exterior of a structure to an interior of a structure. The directed light is then distributed as necessary within the structure for heating, illumination, or is stored for use at a later time.

A system includes a wind turbine with a vertical axis of rotation; and an electric generator that is configured to generate electrical power from rotational energy of the wind turbine. The wind turbine is adapted to be mounted along of a vertical corner of a building.

A pivot window includes a laminated body. The laminated body includes two sheets of a plate material; a peripheral end member provided at a peripheral end parts of the two sheets of the plate material; and a cell array plate material which is interposed between the two sheets of the plate material and which has a plurality of cells respectively having a gas phase and encapsulating a latent heat storage material having a melting point and a freezing point in a specific temperature range. The pivot window further includes a rotation mechanism for causing the laminated body to perform at least half rotation in a vertical direction.

A defogger defogs a reflective mirror with heat from sunlight without relying on electric power. A defogger for a reflective mirror includes a heat collector with a hollow structure to store heat from sunlight, an air inlet port through which air is fed into the heat collector, a warm-air outlet port through which air from the heat collector is discharged in a heated state, a support attached to a pole of the reflective mirror, and a connector connecting the heat collector and the support. The structure allows warm air discharged through the warm-air outlet port to come in contact with the surface of the reflective mirror to increase the surface temperature and thus defog the reflective mirror.

The method is for conveying solar power from a sun. A solar concentrator conveys and concentrates solar power as rays into a glass rod. The solar concentrator has a tapering device disposed at a bottom thereof. The glass rod has a first curved glass loop section, a second curved glass loop section and a straight glass section. The straight glass section has an outer end that is positioned in proximity to a water surface to heat the water. The first loop section is rotated relative to the second loop section at a first gap and the second section is rotated relative to the curved section at a second gap so that the concentrator can follow the path of the sun during the day.
