The shore end of the cable runs into a new reinforced-concrete building set back about a hundred meters from the high-tide level. It is basically just a big room filled with batteries, generators, air-conditioning units, and racks of electronic equipment. The software running on that equipment is Randy’s responsibility, and so he spends most of his time in that building, staring into a computer screen and typing. From there, transmission lines run up the hill to the microwave tower.
