Mobile machine can make biofuel for military and humanitarian operations
Researchers at the U.S. Department of Energy's Argonne National Laboratory (ANL) have created a device called the Endurance Bioenergy Reactor (EBR) that can produce bioenergy on location, using waste from kitchens and latrines. The fuel can go directly into engines and generators without any need for refining, avoiding the complications of distribution and supply chains associated with fuel production. The researchers say the EBR can produce 25 to 50 gallons (94.6 to 189.2 liters) of biofuel a day from waste streams or processed cellulosic materials. Read More
New method may lead to improved detection of nuclear materials
Scientists at Northwestern University, Illinois, have outlined a new method for detecting electromagnetic radiation at the high energy end of the spectrum. The work could lead to the development of a small, hand held device able to detect this "hard radiation" and has implications for the detection of radioactive materials which could potentially be employed in terrorist weapons, such as nuclear bombs or radiological dispersion devices, as well as materials employed in clandestine nuclear programs.

U.S. scientists have developed a new miniature, wearable Positron Emission Tomography (PET) scanner which enables the simultaneous study of brain function and behavior in animals. PET scans are much like Computed Tomography (CT) scans and have helped uncover the molecular underpinnings of conditions like drug addiction, brain diseases such as dementia and they have been used in the medical imaging of cancers.

Hybrid technology is slowly beginning to make its mark on the roadways as manufacturers of cars, buses and trucks embrace it as a cleaner, more efficient alternative. Efforts are also underway to expand this type of technology on the water - Foss Maritime announced plans to build the world's first true hybrid tug boat in early 2007 and now GE and the C-MAR Group hope to demonstrate the feasibility of a hybrid tugboat technology that will both conserve fuel and reduce emissions.

March 5, 2008 Hydroelectric dams produce little-to-no emissions and draw energy from a renewable resource, but they are still plagued with the inherent problems of all large-scale power plants: they’re costly to build and maintain, land intensive, and have negative environmental consequences. That’s why Bourne Energy believes the future of hydropower, and the solution to global energy demand, is in small generators that harness power from river currents. The company's RiverStar power modules collect kinetic energy by passing the water through low RPM turbines that don’t harm aquaculture. The units can be cheaply mass-produced, and require no construction on river bottoms, allowing them to be installed quickly and inexpensively even in areas inhospitable to development. Read More
February 14, 2008 In another innovation that promises to aid us in reducing our carbon footprint, Hydromatic's new energy saving technology targets one of the biggest energy guzzling appliances found in the home - the clothes dryer. Launched at the 2008 International Builders’ Show in Orlando, the Dryer Miser system uses a specially-engineered fluid in the heat exchange process to reduce energy consumption by up to 50% and cut clothes-drying time by up to 41%.
