Abstract: A demountable wind-resistant sunshade canopy for shading children's play areas or other actively used areas. The canopy device is removably secured over a support structure, and is comprised of a hip beams supported by columns mounted on the support structure, and the hip beams extend upwardly and inwardly toward an apex or ridge beam. Cantilevered ends of the hip beam extend beyond the support structure, providing shade for equipment, such as children's play equipment or other actively used areas.
Abstract: An arrangement practical by its efficiency and cost of materials, for converting sunlight into electricity using silicon solar cells. The cells are disposed in facing relation such that sunlight in concentrated form, as provided by a cooperating sunlight-gathering lens, impinges thereon and also is inter-reflected between the cells, so that the electrical output is significantly enhanced.
