Mold blocks and methods for thermoforming corrugated plastic pipe that provide a uniform vacuum on the internal lateral surface and optimize forced convective cooling on exterior surface is disclosed. Devices of the invention are particularly suitable for use on one side of a membrane, such as fabric membrane, to provide electrical power or visible light on the same, or on an opposing side, of that same membrane, or at a distance from where the radiant energy is gathered. Source and destination ports are displayed as icons with each icon bearing a label that describes the corresponding source or destination. The recorded file operations corresponding to said set of records are applied to said copy of the source data until a marker record corresponding to a consistency point marker is determined. Embodiments of the invention include SRAMs, bipolar transistors, SOI lateral diodes, MOSFETs and SiGe Transistors. Photons from the gas discharge within a microsphere excite a phosphor such that the phosphor emits wavelengths in the visible andor invisible spectrum.
