12 If the reader visits the "electrical exhibit" at the Smithsonian Institute he will find photographs ofthe Niagara Fails power plant and a large brass "boiler plate", from one of its original huge generators, listing Testa's patents covering the electrical power system. In the midst ofthe Niagara Falls section stands a lifesize replica of Edison with the comment, "While the Niagara AC plant was being built by Westinghouse, Edison was busy with oilier important things." One is not told what these things, considered by the curator ofthe Smithsonian to be so important, were, nor why it was thought that ihis was relevant to the Niagara AC power plant.

III The analogy advanced by Firestone is called ihe f-i (force-current) analog. With the latter, F~ 1, v-x, mass - capacitance, spring - inductance. In the f-i analog, not only are the equations formally similar, but mechanical elements in series are represented by electrical elemenls in scries (electrical nodes are analogous to median icai junctions). In the f-i case N| - r, and N2 1i is recognized that the f-i and f-v analogies are duals to one another.

S1 The term ''multiply connected" implies that there exists a closed path in the resonator which cannot be shrunk to a point without part of the path passing through regions outside the resonator. A toroidal shaped ring resonator and the earth-ionosphere cavity are examples. The latter has the added feature that it focuses converging energy at the antipode.

Alternative Energy

Alternative Energy

It seems like the efforts to find the best alternative energy sources are seriously being looked into by lots of countries including most US cities. One proof is the signing of the Kyoto Treaty. The main aim of the concerned group and individuals is to lessen the greenhouse gases and pollutants.
