Non-conventional power transmission systems

The rate of growth of electrical power generation and distribution in the United States is so large that the electrical systems in use, should be almost continuously reevaluated in search of better alternatives. One pressing need is for an alternative to large overhead systems. One obvious alternative is underground cable, but practically all facets of present underground systems could stand improvement. There is a need for UG systems with: (a) greater power handling capacity, (b) less loss, (c) smaller capacitance per unit length, (d) lower cost, and (e) better heat dissipation. And the optimum solution might not be in cables at all.
