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: A network-based file-sharing system includes a first host computer and a plurality of other host computers, each host computer having a processing unit and a storage. The first host computer is programmed to generate from the plurality of other host computers a list of other host computers where a user-selected file is stored. The first host computer is further programmed to select a second host computer from the list of other host computers based on an indication of a transfer time from the second host computer to the first host computer and to retrieve at least a portion of the particular file from the second host computer using User Datagram Protocol data packets.
