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
12+ hour, 7+ min 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
2+ day, 10+ 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
2+ day, 16+ 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
2+ day, 23+ 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…...
A German flying wind turbine is being taught to freeze in midair when birds get too close, and on big insect-migration days its safest move is simply to come home
2+ day, 22+ hour ago (562+ words) A flying wind turbine being developed in Germany can respond to wildlife in ways traditional turbines cannot. Developed by Kitekraft, the device flies high above the ground and functions like a kite. It has been created with environmental concerns in…...
An export cable 105 miles long runs from a wind farm 30 miles east of Montauk to a station on Long Island, and the current inside it never changes direction the way every other line in the country does
2+ day, 23+ hour ago (775+ words) Every long cable is a capacitor whether anybody wanted one or not. Conductor down the middle, a layer of insulation around it, and conductive seawater pressed against the outside. That is the exact recipe, and it does nothing at all…...
Five turbines rated at 30 megawatts stand off an island whose summer peak is 4, and the offshore wind that ended its diesel era mattered less than the cable laid to carry it away
3+ day, 16+ hour ago (794+ words) For decades the fuel came in by barge, and the island turned it into electricity itself. A hall of diesel engines ran around the clock because there was no alternative. On a morning in May the engines stopped, and this…...
A power kite has spent more than three years drawing figure eights over Mauritian cane fields, on an island where the only native mammals are bats
3+ day, 20+ hour ago (655+ words) The only mammals that are endemic to the island of Mauritius are bats. Any renewable energy projects must take the animals into account to balance clean power with the ecosystem. Kite power generation is a niche sector of wind farming,…...
One crane vessel set all 72 foundation tubes for Denmark's largest offshore wind farm in five months, and the covers capping their open tops were designed to be taken off and used again
3+ day, 23+ hour ago (808+ words) A yellow steel tube stands in open water off the Danish coast with nothing on top of it. It went in on the last day of April. It has been standing there ever since. The top is open, and a…...
An offshore wind turbine 80 miles off the northern English coast lost a 350-foot blade in a North Sea storm, and it became the third failure of that turbine model in a single year
4+ day, 19+ hour ago (807+ words) A turbine that is turning is protecting itself. Every blade passes through the load instead of standing in it, and the machine keeps hunting for the angle that costs it least. Stop all of that and the protection stops with…...
