The US Department of Energy will be using fuel cells to power the refrigeration units of f...

The refrigeration units used in cold transport trailers are typically powered by small diesel engines, which use up non-renewable fuel and release greenhouse gases, just like their big brothers. The US Department of Energy, however, is looking into an alternative. As part of a two-year pilot project, it’s equipping four such trailers with clean-running hydrogen fuel cells.  Read More

The competition is due to take place this October (Image: Team Stanford)

Since its inception back in 2002, the biennial US Department of Energy-sponsored Solar Decathlon has given collegiate teams a chance to show off their best solar powered home designs. Gizmag takes a closer look at five of this year's 20 entrants which will compete in October.  Read More

The DALE micro-home is the work of a collaboration between SCI-Arc and Caltech students

Students from the Southern California Institute of Architecture (SCI-Arc), and California Institute of Technology (Caltech), have joined forces to produce a net-zero micro-home concept for 2013's Solar Decathlon competition. Dubbed "DALE," the futuristic dwelling is able to expand in size, for those situations in which you don't want your micro-home to be quite so micro.  Read More

A diagram of the process utilized by the Endurance Bioenergy Reactor

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

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.  Read More

PET scans of a rat's brain made with the RatCAP scanner measuring levels of dopamine, whic...

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.  Read More

GE and the C-MAR Group unite to design hybrid tugboat

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.  Read More

Bourne Energy's RiverStar

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

HTC Hydronic Dryer technology

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%.  Read More

Bionic eye offers hope to the blind

Sandia National Laboratories have released a prototype "eye-chip" that may eventually achieve the miraculous goal of restoring sight to the blind. Part of an ambitious project involving several US national labs and Universities...  Read More
