Wave energy generator pumps power to Scotland Wave energy got a boost with the connection of the Oyster hydro-electric device to the electricity grid in Scotland last Friday. Aquamarine Power activated the connection of the Oyster in the waters off Orkney, marking one of the few ocean power devices to be producing electricity. The device is a hydraulic pump operated by a "hinged flap," where a large metal piece moves back and forth from the motion of the waves. The movement moves a hydraulic piston that pumps water underground to a hydro-electric turbine that drives a generator to make electricity.

GISS: G.Projector - Global Map Projector G.Projector transforms an equirectangular map image into any of over 125 global and regional map projections. Longitude-latitude gridlines and continental outlines may be drawn on the map, and the resulting image may be saved to disk in GIF, JPEG, PDF, PNG, PS or TIFF form. G.Projector is a cross-platform application that runs on Macintosh, Windows, Linux and other desktop computers. The current version of G.Projector is 1.8, released 2015-09-18. Get G.Projector G.Projector requires that your computer have a Java 7 or 8 runtime environment, or better, installed. Fracking accident leaks benzene into Colorado stream Once again, Colorado’s fracking boom has residents wondering if there’s something in the water — carcinogenic benzene, in this case. A plant for fracked natural gas processor Williams Energy, near Parachute, Colo., spilled an estimated 241 barrels of mixed natural gas liquid into the ground, some of which eventually washed as benzene into Parachute Creek. More than two months after the spill was discovered , neighbors of the plant are wondering why the energy company is being put in charge of the cleanup — and why the state has failed to issue any fines. Benzene levels in Parachute Creek rose above a safe-to-drink 5 parts per billion following the spill, which was caused by a faulty pressure gauge on a four-inch pipeline.

Twenty top predictions for life 100 years from now 16 January 2012Last updated at 08:50 Last week we asked readers for their predictions of life in 100 years time. Inspired by ten 100-year predictions made by American civil engineer John Elfreth Watkins in 1900, many of you wrote in with your vision of the world in 2112. 3.5 million ha of Indonesian and Malaysian forest converted for palm oil in 20 years Palm plantations expanding at 7% per year across Malaysia and Indonesia Oil palm plantation area and forested area (ha) in Peninsular Malaysia, 1975-2009 Some 3.5 million hectares (8.7 million acres) of forest in Indonesia, Malaysia, and Papua New Guinea was converted for oil palm plantations between 1990 and 2010, finds a comprehensive set of assessments released by the Roundtable on Sustainable Palm Oil (RSPO). The research, conducted by an international team of scientists from a range of institutions, is presented in a series of seven academic papers that estimate change in land use and greenhouse gas emissions from oil palm expansion in the three countries, review the social and environmental impacts of palm oil production, forecast potential growth in the sector across the region, and detail methods for measuring emissions and carbon stocks of plantations establishing on peatlands. Most of the forest area that was converted consisted of disturbed natural lowland forest.

World’s largest working hydro-electric wave energy device launched Queen's University Belfast has helped the global wave energy industry take a major stride forward with the launch of the world's largest working hydro-electric wave energy device by Aquamarine Power Ltd. Known as Oyster, the device has been officially launched by Scotland's First Minister Alex Salmond MP, MSP at the European Marine Energy Centre (EMEC) in Orkney. It is currently the world's only hydro-electric wave energy device producing power and is now producing power by pumping high pressure water to its onshore hydro-electric turbine. This will be fed into the National Grid to power homes in Orkney and beyond. Geophysics Age of the sea floor. Much of the dating information comes from magnetic anomalies. Geophysics /dʒiːoʊfɪzɪks/ is the physics of the Earth and its environment in space; also the study of the Earth using quantitative physical methods. The term geophysics sometimes refers only to the geological applications: Earth's shape; its gravitational and magnetic fields; its internal structure and composition; its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formation.[1] However, modern geophysics organizations use a broader definition that includes the hydrological cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial relations; and analogous problems associated with the Moon and other planets.[1][2][3] Although geophysics was only recognized as a separate discipline in the 19th century, its origins go back to ancient history.

Welcome to Portage County, the Fracking Waste Disposal Capital of Ohio Welcome to Portage County, Ohio, the biggest dumping ground for fracking waste in a state that is fast becoming the go-to destination for the byproducts of America's latest energy boom. As fracking—pumping a briny solution of water, lubricants, anti-bacterial agents, and a cocktail of other chemicals into underground shale formations at high pressure to fracture the rock and extract trapped natural gas—has expanded in the Midwest, so has the need for disposing of used fracking fluid. That fracking waste can be recycled or processed at wastewater treatment facilities, much like sewage.
