    • Digging into geothermal energy (PhysOrg)- May 19, 2011
    • Sixteen undergraduate students at the School of Engineering and Applied Sciences (SEAS) may now be Harvard's resident experts on geothermal energy. For their capstone project in the course ES 96: Engineering Design Seminar, these students conducted an in-depth analysis of the geothermal heating and cooling system that serves Radcliffe's Byerly Hall.

    • Resolving water's electrical properties (PhysOrg)- May 18, 2011
    • An old confusion about the electrical properties of water's surface has ended, thanks to scientists at Pacific Northwest and Lawrence Livermore National Laboratories. The conflict arose because two types of measurements gave two radically different interpretations of what was happening at the surface of water. More...
    • A Tribute in Memory of Professor Ralph L. Webb (1934 - 2011) (Thermal-Fluids Central)- May 17, 2011
    • On April 3, 2011, Dr. Ralph L. Webb, Professor Emeritus of Mechanical Engineering at Pennsylvania State University, passed away in State College, Pennsylvania at the age of 77. Dr. Webb made significant contributions in the field of enhanced heat transfer with applications in the areas of boiling, condensation, fouling, air-cooled heat exchangers, electronic equipment cooling, and forced convection for gases...

    • New Solar Product Captures Up to 95 Percent of Light Energy (ScienceDaily)- May 17, 2011
    • Efficiency is a problem with today's solar panels; they only collect about 20 percent of available light. Now, a University of Missouri engineer has developed a flexible solar sheet that captures more than 90 percent of available light, and he plans to make prototypes available to consumers within the next five years.

    • Which technologies get better faster? (PhysOrg)- May 17, 2011
    • Some forms of technology — think, for example, of computer chips — are on a fast track to constant improvements, while others evolve much more slowly. Now, a new study by researchers at MIT and other institutions shows that it may be possible to predict which technologies are likeliest to advance rapidly, and therefore may be worth more investment in research and resources.

    • New Properties of Supercooled Confined Water Discovered (ScienceDaily)- May 16, 2011
    • A study led by the UB researcher Giancarlo Franzese and published in the journal Physical Review Letters suggests that hydrophobic nanoconfinement can alter the thermodynamics of water at supercool temperatures. These findings may have important applications in fields related to conservation at cryogenic temperatures (around -100 ºC) -- for example, in the preservation of stem cells, blood and food products...

    • Turning plants into power houses (PhysOrg)- May 12, 2011
    • "I have a slide that has a photo of a cornfield and a big photovoltaic array," says Robert Blankenship, a scientist who studies photosynthesis at Washington University in St. Louis. "When I give talks I often ask the audience which one is more efficient. Invariably the audience votes overwhelmingly in favor of photosynthesis." They are wrong. This question and its surprising answer (below) is the point.. More...
    • Turning Waste Heat Into Electricity (ScienceMag)- May 4, 2011
    • Engineers have come up with a handful of uses for computer chip-like devices that chill objects when plugged in or convert waste heat into electrical power—stuff like car seats that cool drivers on hot days and coolers that chill drinks when plugged in. But by-and-large, these devices, known as thermoelectrics, have remained too inefficient to make much of a real-world impact... More...
    • Solar power, with a side of hot running water (PhysOrg)- May 3, 2011
    • MIT researchers and their collaborators have come up with an unusual, highly efficient and possibly less expensive way of turning the sun’s heat into electricity. Their system, described in a paper published online in the journal Nature Materials on May 1, produces power with an efficiency roughly eight times higher than ever previously reported for a solar thermoelectric device — one that produces electricity from solar heat...

    • Exelon-Constellation Deal Could Create 'Clean Energy' Giant (The New York Times)- April 29, 2011
    • Exelon Corp.'s $7.9 billion bid to buy Constellation Energy builds on a series of recent deals meant to create profitable electric power companies that burn less coal, use more natural gas and combine existing nuclear fleets. Early yesterday, Chicago-based Exelon and Baltimore-based Constellation proposed a merger that would combine the nation's largest operator of nuclear power plants with a large marketer of electricity along the East Coast...
