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
48+ 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…...
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, 10+ 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…...
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
3+ day, 9+ 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…...
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
5+ day, 5+ 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…...
Tomato leaves under a solar array took in 47 percent less light in a new simulation, while the carbon they fixed fell by only 31 percent and the panels overhead ran about 10 degrees cooler
4+ day, 23+ hour ago (733+ words) Put a roof over a crop and the crop gets less light. That much is arithmetic. What most people then assume is that the yield falls by the same fraction. It does not, and the gap between those two numbers…...
Steel foundations under a Dutch wind farm came in 2 diameters that differ by about 20 inches, and the wider ones carry taller towers raised to leave a bird corridor open across the site
6+ day, 2+ hour ago (852+ words) On the yard quay the tubes lie in cradles, end on, and they look identical. They are not. Stand where the rims almost line up and one is wider than the other by about 20 inches. Half a meter of steel,…...
Across 243 solar farms in China’s drylands, satellites found the panels were quietly rewriting the seasons by bringing spring nearly two weeks early and stretching the growing period by 16 days
1+ week, 1+ day ago (444+ words) More than 200 solar facilities in China are being analyzed through high-resolution satellite imagery. An unexpected environmental shift is happening in the drylands. The vegetation under and around the solar panel arrays is sprouting way ahead of the normal schedules for…...
A New York solar farm took 24% of the fall light away from its vegetables, and the radishes and radicchio ended the season with almost half their normal biomass
1+ week, 2+ day ago (529+ words) Agrivoltaics is a buzzword in renewable energy, and the practice is intended to boost agricultural efficiency. However, a trial in New York State indicated late-season compromises for plants that need lots of light to build biomass. The location of the…...
Vatican farmland northwest of Rome runs to about 10 times the size of the country itself, and it will carry up to 90 megawatts of agrivoltaic solar with the crops still growing underneath
1+ week, 4+ day ago (814+ words) Put a solar farm on farmland and you normally lose the farm. Panels sit low, rows run close, and the ground underneath goes to gravel or mown grass for thirty years. That is the trade every planning board in Europe…...
Sunlight a Swedish molecule holds for 18 years traveled to a bench in Shanghai and came back out through a chip of films a micrometer thick, and the whole yield was a tenth of a billionth of a watt
1+ week, 5+ day ago (787+ words) The liquid had already been charged by sunlight. Its molecules had been rearranged, atom for atom, so that the energy sat locked inside their chemical geometry rather than in a cell or a wire. Then it was crated and flown…...
