A University of Illinois research group brought together aspects of condensed matter physics, semiconductor device engineering, and photochemistry to develop a new form of high-performance solar photocatalyst based on the combination of the TiO2 (titanium dioxide) and other "metallic" oxides that greatly enhance the visible light absorption and promote more efficient utilization of the solar spectrum for energy applications.
Artificial photosynthesis is a dream technology that mimics a natural leaf, converting water and carbon dioxide into fuels with sunlight. But before this technology can take flight, scientists will have to solve a fundamental plumbing problem: how to gather molecules of fuel from microscopic reaction sites to pipes that will pour it out by the gallon.
The EU-funded project, called SUPRAPOWER, is working on a more powerful, reliable and lightweight superconducting offshore wind turbine. The four-year project has the expertise of nine European partners from industry and science under the coordination of Tecnalia in Spain.
The first continental-scale reconstruction of temperatures over the past 2000 years has found 20th Century warming was a global event that has produced the hottest global average temperature in 1400 years.
Scientists have announced a collaboration to develop an affordable photovoltaic system capable of concentrating, on average, the power of 2000 suns, with an efficiency that can collect 80 percent of the incoming radiation and convert it to useful energy.
Recycling of tyres is a potentially economically sustainable enterprise providing an ingredient to make a kind of plastic for ever recyclable. But Europeans first need to overcome barriers to adoption.
In the 1990s, scientists described the vision of a 2000 W society, in which each person in the developed world would cut the overall power demand to an average of no more than 2000 W and emit no more than 1 ton of CO2 per year without lowering the living standard. A new survey concludes that a continuous consumption of not more than 2000 W per person seems possible for the major part of the population in this society. However, it will be far more difficult not to exceed 1 ton CO2 per capita.
Representatives from internationally-recognised blue chip organisations including IBM, Cisco, Microsoft and Citrix gathered at Birmingham City University earlier this month to address the problems of energy and material waste within the computing and technology industries.
