THE ICE TEST
Whether the tall turbine masts can survive ice sheets comes down to two primary innovations: Lake Erie is the shallowest of the Great Lakes, and averages about 78 percent ice coverage each winter, the highest of the five lakes.
Icebreaker will install an inverted cone on the towers at the water level. The idea is that by tapering from a wide flare higher up on the mast down to a narrow base at the waterline, the cone can deflect ice flowing toward the masts, pushing it down and away.
The second innovation that will be tried on Icebreaker involves how the masts will be attached to the lake floor. The “mono bucket,” a suction cup–style, circular steel bucket, 56 feet in diameter, will form the foundation. …
