Público.es Synthesized 'solar' jet fuel: Renewable kerosene from sunlight, water and carbon dioxide With the first ever production of synthesized "solar" jet fuel, the EU-funded SOLAR-JET project has successfully demonstrated the entire production chain for renewable kerosene obtained directly from sunlight, water and carbon dioxide (CO2), therein potentially revolutionizing the future of aviation. This process has also the potential to produce any other type of fuel for transport applications, such as diesel, gasoline or pure hydrogen in a more sustainable way. Several notable research organizations from academia through to industry (ETH Zürich, Bauhaus Luftfahrt, Deutsches Zentrum für Luft- und Raumfahrt (DLR), ARTTIC and Shell Global Solutions) have explored a thermochemical pathway driven by concentrated solar energy. A new solar reactor technology has been pioneered to produce liquid hydrocarbon fuels suitable for more sustainable transportation.
Diane Ravitch Público Philadelphia Public School Notebook Feeling the heat over steam; Critics want a review of oilsands extraction process after Cold Lake leaks Oil glistens on water as booms line a marsh during the ongoing cleanup of bitumen seepage at Canadian Natural Resources Ltd.'s Primrose East oilsands project. Photograph by: Ed Kaiser , Ed Kaiser Originally published August 10, 2013. COLD LAKE - In a hard hat and overalls, Canadian Natural Resources Ltd. president Steve Laut stands on a new boat launch on the edge of a marsh while behind him a fleet of watercraft are skimming an oily film off the water. Noise cannons are booming, screeching recorded bird calls, plastic flags and decoys help keep wildlife away from this site where bitumen is leaking into the water on the company's Primrose East oilsands project near Bonnyville. About 80 per cent of Alberta's oilsands will be extracted by in situ methods as opposed to open pit mines. Some say this method is more environmentally friendly than mines that carve up the earth. On the four sites, the leaks are now contained and the bitumen is vacuumed up daily or weekly. spratt@edmontonjournal.com
