    • Capturing Waste Heat with Organic Rankine Cycle Systems (RenewableEnergyWorld.com)- January 24, 2011
    • Waste heat and low-temperature geothermal are hot sources of renewable energy that get a boost from Organic Rankine Cycle (ORC) systems. In Brisbane, Australia, a 240-kW ORC unit at a timber plant will soon harvest heat from an existing biomass burner and generate electricity to power kilns for drying lumber. Similar ORC systems are becoming killer add-ons for other heat-based renewable energy plants, including concentrating solar and utility-scale geothermal systems. “People are realizing now... More...
    • Another Way to do Solar Thermal? (greentechSolar)- January 18, 2011
    • Keep it low to the ground. Video too. Think of this as solar thermal with a bank shot.Researchers at the Masdar Institute, the Tokyo Institute of Technology and Cosmo Oil have begun to test a new/old technology for converting heat from the sun into electricity that could further cut costs. It works by adding another layer of mirrors to the process. In Masdar’s prototype, ground-based heliostats-i.e. flat mirrors -- concentrate heat from the sun and aim it at a tower. So far, that’s similar t... More...
    • Radiant Heating and Cooling Systems: A Smart Alternative to Convective Systems? (green-buildings.com)- January 13, 2011
    • Convection is the most common form of building heating and cooling... but what about radiation? Most people are familiar with ‘all air’ HVAC distribution systems, in which air is the fluid by which both ventilation air from the outdoors and warm or cold air (for heating or cooling, respectively) is delivered to a space. There are many, many types of air-side systems and their associated fans must be sized to move both the peak cooling load plus the ventilation air. This distribution method u... More...
    • Freezing out danger (www.defencemanagement.com)- January 8, 2011
    • Didier Guffond, of French aerospace laboratory ONERA's Physics, Instruments and Sensing department, looks at some of the ways in which military aircraft are protected against ice deposits. Atmospheric ice is a meteorological hazard that may affect an aircraft's operations. It is formed when supercooled droplets impact on the front part of different structures. Ice deposits on aircraft surfaces affect the aerodynamic performance of lifting and control components, directly influence the safety of ... More...
    • Gasoline From Water, CO2 and Sunlight (LaboratoryEquipment.com)- January 7, 2011
    • Scientists ask themselves: how can we get hold of the vast, yet intermittent and unevenly distributed, solar energy resource such that it can be stored and transported from the sunny and uninhabited regions of the earth’s sunbelt to the world’s industrialized and populated centers, where much of the energy is required? This question has motivated the search for recipes to transform sunlight into chemical energy carriers in the form of storable and dispatchable liquid fuels, such as gasoline ... More...
    • Bid to keep aluminium shining (Science Alert)- January 6, 2011
    • Cutting deeply into Australia’s overall energy consumption by changing how a single industry operates sounds ambitious. But even small improvements to the way aluminium is made can save a lot of energy, along with jobs and future investment, as global pressures to cut carbon emissions rise. Seeking a better way to make aluminium – one of Australia’s biggest industries that last year exported $5 billion worth of metal, directly employed 13,000 people and consumed 14 per cent of all electric...

    • We might create dark matter in our labs in 5-10 years (The Economic Times)- January 5, 2011
    • Thanu Padmanabhan, a distinguished professor at the Inter-University Centre for Astronomy and Astrophysics,rnNEW DELHI: Thanu Padmanabhan, a distinguished professor at the Inter-University Centre for Astronomy and Astrophysics, Pune, was awarded the Infosys Foundation Prize 2009 for Physical Sciences this week for his contribution to a deeper understanding of Einstein’s theory of Gravity in relation to thermodynamics. In an interview with ET, Prof Padmanabhan talks about the behaviour of black... More...
    • On the thermodynamics of algal biodiesel production systems (Philstar.com)- December 30, 2010
    • Biodiesel is the term used for derivatives of vegetable oils and animal fats that have been chemically modified so that their physical properties resemble those of diesel fuel. This chemical modification ensures that they can be used as fuels for diesel engine without posing significant risk of damage, and without any drastic changes in performance. There are many environmental benefits that have been attributed to biodiesel use, including biodegradability and reduction of emissions of greenhous... More...
    • U.S. Considering Its First-Ever Regulations for Disposal of Coal Ash (Solar & Home Business Journal)- December 30, 2010
    • About 45 percent of the electricity generated in the United States this year has come from coal-fired power plants, according to the U.S. Energy Information Administration. As a combustible fuel, coal has key advantages, including low costs. Recent mining tragedies have served as a reminder that coal has drawbacks as well. The advantages of burning coal to produce electricity are realized by almost everyone in the form not just of lower electricity prices but also of reduced costs for practicall... More...
