Typically, modern offshore wind turbines come in only one size and shape – really big, rising up from the ocean floor. The University of Maine, with support from the Department of Energy, has just launched a new test design, the first grid-connected floating wind tower. The tower, launched in Brewer, Me., is supported by three hollow concrete tube floats and will be anchored in the Gulf of Maine. VolturnUS 1:8, which sounds like something from a bad science fiction novel, is only 20 kw in capacity but, should it succeed, the design should be scalable up to much larger installations. Using a floating rather than a fixed platform would allow wind turbines to be installed in much deeper water on the West Coast of the US and along the Maine Coast.

It is a conical shaped structure built of boulders, roughly 230 feet in diameter, 30 feet high and weighing an estimated 60,000-tons, 40 feet underwater in the Sea of Galilee. And archaeologists have no idea what it is. Based on the build up of sediment, it is between 2,000 and 12,000 years old, which is too wide a range to help identify it. It’s not even clear if the structure was built on land when the sea levels were lower, or if it was constructed underwater. The structure was located in 2003 by sonar scan. Now ten years later, researchers from the Israel Antiquities Authority are mounted an expedition to attempt to learn more about the unexpected mound of boulders, which they speculate could have been a burial site, a place of worship or even a fish nursery.
