This ribbon of photovoltaic cells was the third of the four great Planetary Projects completed by the United Nations in the early Twenty-fourth Century. The array was named for Nicola Tesla – the inventor of alternating current and an early experimenter of broadcast electric power. It is positioned 100km to the south of the Sanchez Ring within ten kilometers of the Gell-Mann SSC. The array is a lattice containing fifty-four thousand billion photovoltaic cells, and has the ability to produce twenty million terawatts of continuous power. This power is collected at sixty-four microwave stations and transmitted to collectors strategically placed around the Earth.
