crew kept the plates repaired, and we saved a thousand dollars worth of steaming fuel a week.
An ocean-thermal generating boat lives off the temperature difference between deep water and sun-warmed surface water. The top water warms the working fluid- a halocarbon with a low boiling point-and it becomes steam and goes through the low-pressure turbines to make electricity; the electricity splits water into hydrogen and fixes nitrogen from the air, and we sell what it makes. The difficulty is the halocarbon working fluid. It is too expensive to vent to the air. It must be condensed and recycled, and for that we need something cold. The sea gives us that. There is plenty of cold water in every deep sea, but it is half a kilometer down or more, and so we must pump it to the surface. Pumping and pumping. Pumping cold water up from the deep. Pumping the working fluid through the solar collectors. Pumping water past the electrodes to be split into its gases; pumping the gases into the refrigerator ships to be carried away. Out of every hundred kilowatt-hours of energy we make, ninety-seven go into running the gear itself.
But that three percent left over makes us rich, for once the boat is built it is all free.
Ben Zoll had never worked on an oaty-boat, and so he had much to learn He learned it fast If he did not have the Commodores name, he had at least inherited his drive.
May had the name. And bastard Ben kept her from everything else, kept her from the presidency of the Fleet, kept her from the voting rights to her stock.
He did not begrudge her money. She had the best schools. She had horses to ride and clothes for a princess. It was no sacrifice to Ben to allow her any money she needed. The billions of land people hungered insatiably for every grain of ammonia and every wisp of hydrogen we could make. The company prospered under bastard Ben.
And so did I, for my pitiful fifty shares of stock had already made me a millionaire. I didn't need the job anymore. But I kept it, and I stayed on the O.T. Where else was there to go? No sensible person would want to live on a continent with all those writhing billions. Land people are a suing, assassinating, conniving bunch. And I had formed the habit of living under the Law of the Sea- And, besides, every now and then May came home to visit.
She did not come often. But there were school holidays. Any time there were afew days together, she would take the long five-hour flight from Massachusetts to the Bismarcks or the Coral Sea or wherever we were grazing, and in the summers, always, for weeks on end. It was not May alone, for the four other Mays always came too, to visit their families and to get away from the stink and strife. They were beautiful girls. Girls to break a thousand hearts, and I suppose they did. There was Maisie Richardson, huge and blond and glowing with health, and May Holliston-Peirce, the hydrologist's daughter, with trusting blue eyes and a sweet, guileful tongue, and Tseling Mei, who became a movie star, and May Bancroft, black and handsome and the wisest of them all. And May herself. My May. She was always the most beautiful of them all. There are pretty babies who grow up blotchy or sullen or fat, but there was never a day in any company when May was not the most beautiful there. They were all almost of an age, May and the four other Mays, and, oh, heaven, how they brightened up the old O.T.! There was a May for any man's taste, and all of them for every taste, for they were kind and clever, they were lovely and loving. They chattered and whispered among themselves, and if ever a joke went the wrong way or a word touched a nerve, they made it up at once with a kindness and a kiss.
And then there was Betsy.
Betsy Zoll. Bitch child of the bastard, Ben. If you take the raw materials for two young women and give all of the beauty and kindness and grace to one-say, to May- what is left over is Betsy Zoll. May was a diamond. Betsy was flawed glass. When the
