Sway founder Eystein Borgen has developed a solution to visually unattractive wind turbines: placing floating turbines 20 miles or more out in the cold waters of the North Sea to harness the stiff, constant breezes could one day power vast windmill fields. Borgen built his first wind turbine at age 13, taping scavenged aluminum sheets to a bicycle wheel and attaching an old bicycle headlamp generator to this homemade fan, and then mounting his contraption on the roof of his parents summer home on the western coast of Norway. With beginners luck or more likely skill, Borgen just needed and soon received a strong gust of wind to bring electric lighting to the home for the first time. Now at age 44, Borgen is still making wind turbines, and Sway is on the cutting edge of the technology. Environmentalists have mixed emotions about wind power: while it is clean and renewable, people do not want to look at the towers and it is getting harder to find spots for turbine farms in densely populated areas. Shallow-water projects ruin sea vistas, so Borgen came up with the solution of putting windmills farther out to sea, where only the whales can see them. According to Borgen, two thousand windmills would power all of the homes in Norway, and while such a park would span 400 square miles, that is just a relatively small speck in the vast northern sea. Borgen borrowed technology from the offshore drilling industry and designed a floating, strawlike mast, tethered to the ocean floor by a steel pipe, on which to mount his wind turbines. Sway has landed investments from Norways oil-and-gas giant StatoilHydro, and Norwegian power utility Lyse. Oceans offer limitless scale even though deepwater wind could be twice as expensive to harness.
