New wireless power transmission techniques are disclosed. In some aspects of the invention, a system distributes wireless power from a power and information transmitting base station, through a network of intermediate wireless power enhancement and consumption devices, each of which may be independently owned and controlled. The system may assign invoices comprising monetary credits and debits, based on each device's use or enhancement of the wireless power provided through the network. Other power storage and transmission techniques are also disclosed, including a new form of universal battery, with variable space-filling aspects and a central battery core with improved, flexibly-applied contacts.
