A visible image showing powerful Hurricane Matthew and Nicole on Oct. 6 at 1 p.m. EDT was captured by NOAA's GOES-East satellite. The image shows large Hurricane Matthew's clouds stretching from eastern Cuba and Hispaniola, over the Bahamas and extending to Florida. Matthew is west of the much smaller Tropical Storm Nicole. The image was created at the NASA/NOAA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
Nearly two years ago, Sandia National Laboratories researchers Joe Pratt and Lennie Klebanoff set out to answer one not-so-simple question: Is it feasible to build and operate a high-speed passenger ferry solely powered by hydrogen fuel cells? The answer is yes.
The details behind that answer are in a recent report, “Feasibility of the SF-BREEZE: a Zero Emission, Hydrogen Fuel Cell High Speed Passenger Ferry.” SF-BREEZE stands for San Francisco Bay Renewable Energy Electric Vessel with Zero Emissions.
New research from North Carolina State University finds that urban warming reduces growth and photosynthesis in city trees. The researchers found that insect pests are part of the problem, but that heat itself plays a more significant role.
It was believed that efficient operation of organic solar cells requires a large driving force, which limits the efficiency of organic solar cells. Now, a large group of researchers led by Feng Gao, lecturer at IFM at LiU, He Yan at the Hong Kong University of Science and Technology, and Kenan Gundogdu at the North Carolina State University have developed efficient organic solar cells with very low driving force.
This implies that the intrinsic limitations of organic solar cells are no greater than those of other photovoltaic technologies, bringing them a step closer to commercialisation.
Scientists at Oxford University have developed a solvent system with reduced toxicity that can be used in the manufacture of perovskite solar cells, clearing one of the barriers to the commercialisation of a technology that promises to revolutionise the solar industry.
Perovskites – a family of materials with the crystal structure of calcium titanate – have been described as a 'wonder material' and shown to be almost as efficient as silicon in harnessing solar energy, as well as being significantly cheaper to produce.
Berkeley Lab desarrolla un mejor método de vigilancia del medio ambiente mediante el PhyloChip, que encuentra resultados sorprendentes en la cuenca del Río Ruso. Cuando la agencia local de manejo de agua cierra tu playa favorita debido a la calidad del agua insalubre, ¿Qué grado de confiabilidad tienen las pruebas en las que se basan sus decisiones?
