• Money is indispensable to a long-circuit heavy load energy system. It must be used when a sufficient surplus is being produced to allow a margin for exchange, and cost of transport, over a considerable distance. Money represents a storage battery when idle, and a generalized mode of the conversion of energy when it is in motion, with a function of equating time and space.
