Abstract: A platform to supply renewable backup power to critical node infrastructure is disclosed. The platform conceals solar photovoltaic modules and storage batteries in plain sight by hiding such components in commonly encountered urban furniture, such as bus shelters. In particular, a bus shelter ad box is used to conceal or cloak certain components of the system.

Abstract: An improved flange removal tool is provided to facilitate the installation and removal of pipe flanges from a receiving pipe fitting. The flange tool includes a body portion with an upper surface which includes a central opening for receiving an engagement head of a socket wrench. A continuous frame is attached to the body portion by spaced arms such that the continuous frame is suspended in spaced relation from the lower surface of the body portion by a distance which is greater than the thickness of a pipe flange to be rotated. The pipe flange is positioned between the body portion and the frame so upon rotation of the flange tool, facilitated by engagement of a socket wrench with the central opening, side walls of the spaced arms contact the edges of the pipe flange to urge rotation thereof and threading onto its receiving pipe fitting.
