Abstract: The present invention relates to a portable solar charging assembly comprising: a photovoltaic array, where the photovoltaic array is less than 8 square inches and capable of generating electrical energy; a border surrounding the array; an outlet, where said outlet provides a connection point for the connection of a cable; and a cable attachment, where said cable attachment connects the array to a battery and transfers electrical energy from the array to the battery. The cable attachment may include a plug at a first end and an attachment mechanism at the second end. The attachment mechanism may include interchangeable connectors that connect to an electronic device and effects the charging of the battery from energy generated by the array. The portable solar charging assembly may also include a back side of the array and at least one suction cup on the back side.

Abstract: A hollow spherical article having at least two substantially diametrically opposed apertures in the spherical surface, said article being of wrought metal and having been moulded by explosive forming. The article may further comprise at least two cylindrical portions, said portions being located on the spherical surface and defining said apertures. The method of forming the hollow spherical article comprises placing a tube of wrought metal into a die, positioning a plurality of explosive charges within the tube and detonating the explosive charges to expand the tube to form said hollow spherical article having two cylindrical portions which may subsequently be removed by machining.
