• Invention: Diamond-cooled nuclear reactor

    Nuclear plants can fail when the heat from the reactor is not removed quickly enough from the core. This can happen in pressurised water nuclear reactors if the water in the cooling system boils, because steam is a much poorer conductor of heat than liquid water. These reactors have a primary water cooling system that directly takes heat away from the reactor. It is sealed under huge pressure to prevent it boiling and conducts heat to a secondary water cooling system that is not sealed. >> Read the Full Article
  • Shell and Virent Partner to Produce 'Biogasoline'

    Royal Dutch Shell and Virent Energy Systems inc. formed a five-year partnership to produce a gasoline alternative from plant sugars that won't impact food prices or need modified gasoline engines. The deal follows a larger trend of oil companies investing in biofuel research. For instance, BP is working with several universities, such as University of California at Berkley and Arizona State University, to transform low-carbon feedstocks into biofuels. >> Read the Full Article

  • Britain extends support for micro-power generation

    LONDON (Reuters) - Britain on Monday said it had extended the timeline for support, but added no new extra money, for small-scale electricity installation using renewable energy sources, called microgeneration. Local production of electricity from the wind and sun, for example using roof-top solar panels and micro wind turbines, is attracting increasing subsidy support worldwide as governments try to curb greenhouse gas emissions from burning fossil fuels. >> Read the Full Article
  • Will South Africa lead the solar energy revolution?

    South Africa, Brazil and other emerging economies are likely to face emissions caps come 2012. Can South Africa’s solar energy ventures compete with its vast supply of cheap coal? Stretched-out plains with dust devils and unrelenting sun are the trademarks of the barren Northern Cape in South Africa. Every year the province records some of the highest numbers of sunny days worldwide. Rainy days are as rare as hen’s teeth. >> Read the Full Article
  • U.S. to propose CO2 rules this spring
