A 30 foot wind turbine blade built with a plant based resin instead of standard epoxy broke down completely in six hours, and the glass and carbon fibers came out clean enough to build with again
7+ hour, 2+ min ago (780+ words) The blade came apart in a sealed steel reactor that holds about two gallons. A 30 foot turbine blade, built with the same molds, layups and cure steps used on commercial blades, was sectioned into cubes and dropped into hot methanol....
Canada will let a new Bay of Fundy tidal farm grow one turbine at a time, then let the fish influence whether the next machine gets installed
12+ hour, 57+ min ago (609+ words) Canada’s Bay of Fundy lies in Nova Scotia’s Minas Passage. The region is notorious for producing the world’s highest tides. More than 100 billion tons of water are moved twice every day. Using this tidal energy to generate clean power has…...
A single offshore wind blade broke apart 15 miles off Nantucket and scattered thousands of fiberglass pieces across beaches and the seafloor, and blades on 22 other turbines were later pulled down as well
15+ hour, 2+ min ago (771+ words) On a Saturday evening in July, something gave way 15 miles southwest of Nantucket. A 351 foot offshore wind turbine blade cracked, and a large section broke free and fell. Within hours, thousands of fiberglass pieces were in the Atlantic. Some washed…...
Wind turbine blade fiberglass soaked in a 2 hour salt bath came back as nylon more than three times stronger and eight times stiffer than before
19+ hour, 2+ min ago (679+ words) The blade has been sitting in a landfill outside Casper, Wyoming, for the better part of a decade. It arrived well over 100 feet long, sawn into sections so it would fit on a semitrailer. Landfill managers describe the fiberglass as…...
A wind turbine off Taiwan got a living coral garden 100 feet beneath the waves, and more than three kinds of coral are now being watched to see whether they stay
18+ hour, 57+ min ago (562+ words) When wind turbines are installed in deep offshore waters, they have the potential to become support structures for artificial coral reefs. This has not been tested much yet, though. Ørsted has launched its ReCoral technology in the Taiwan Strait as…...
Blades pulled off a 250 megawatt Kansas wind farm are being cut into transmission poles instead of buried, but the test pole that was loaded to failure gave way at a steel weld rather than anywhere in the composite
23+ hour, 34+ min ago (789+ words) A wind blade and a power pole are the same structural problem wearing different clothes. Both are tall tapered cantilevers, fixed at one end, carrying loads pushed sideways along their length by wind. Both are sized by bending, not weight....
Piles of concrete pipe were dropped around 1 turbine foundation off the Dutch coast and tagged cod moved in and stayed, where the flat swept sand around them offers nothing to hide inside at all
1+ day, 11+ hour ago (754+ words) The southern North Sea floor is not a landscape. It is a surface. Sand, gravel and shell, graded flat and kept that way, because a century of bottom trawling removed anything that stood up from it. The shellfish reefs that…...
Each of the 89 concrete boxes being cast beside a Danish harbor is 712 feet long and gets towed to sea by tugboats, while the box itself very nearly floats and is sunk on purpose with water pumped into it
3+ day, 9+ hour ago (786+ words) Weight is not what makes an object hard to move across water. Displacement is. A ship of 80,000 tons is moved by tugs every day of the week, and nobody finds it remarkable. So the interesting question about a tunnel section…...
Wales left a yellow buoy watching the sea for two years before putting tidal turbines nearby, and it came home after teaching cameras how to recognize a dolphin
3+ day, 14+ hour ago (524+ words) Dolphin detection was one of the main goals of a bright yellow research buoy named Marinus, which spent over 2 years observing the coastal waters of Ynys Môn before quietly leaving service. This buoy was sent out as part of a…...
Wind turbine blades usually end their lives buried in landfills, but a German manufacturer says its 63-foot wooden blades milled from laminated veneer lumber resist fatigue better and cost about 20 percent less to make
3+ day, 22+ hour ago (801+ words) A workshop floor, a gantry rail overhead, and a long pale shape lying under it that looks like furniture. It is spruce, glued up in layers, and a cutter is walking down its length taking off curls of shaving. What…...
