The lighting system, sponsored by the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) in conjunction with Boeing Co., and developed by Sandia National Laboratories with several industry partners, was deployed to the site of the final space shuttle launch and observed by visitors, shuttle astronauts and members of the international media.
The unit provided lighting in the international press area, and its auxiliary power was used to conveniently recharge the camera battery packs for a number of photographers at the event. The NASA deployment was the latest in a series of high-profile test sites where the lighting system has been utilized.
The hydrogen fuel cell-powered mobile lighting system is a clean, quiet and efficient alternative to traditional technologies commonly powered by diesel fueled generators. The system features a fuel cell running on pure hydrogen, resulting in zero-emission electrical power. The fuel cell produces electricity for an advanced, power-saving Light Emitting PlasmaTM (LEP) lighting system and additional auxiliary power up to 2.5 kW, which allows additional equipment (such as power tools, public address systems or security metal detectors) to be powered by the unit at the same time the system is providing illumination.
Current mobile lighting typically uses diesel fueled generators that produce greenhouse gases such as carbon dioxide nitrogen oxides, which produce pollutants and create smog, and soot, making them environmentally objectionable. In addition, diesel units are noisy and can create a safety hazard when construction personnel are distracted and cannot hear oncoming traffic.
Sandia researchers estimate that a single hydrogen fuel cell-powered lighting system would offset 900 gallons of diesel fuel per year and completely eliminate soot, nitrogen-oxide and carbon-dioxide emissions, allowing the system to be used indoors in contrast to current diesel technology.
“This hydrogen fuel cell-powered mobile lighting system has the very real potential to drastically reduce dependence on diesel-fueled mobile lighting across the United States and abroad,” said Lennie Klebanoff, Sandia’s project lead.
The prototype system has been tested in a variety of environments and has primarily focused on the entertainment, transportation and airport sectors. In addition to NASA (which also used the system during the Space Shuttle Endeavor launch) customers who have provided test sites include the California Department of Transportation, the 2010 Academy Awards ceremony, the 2011 Golden Globe Awards, the 2011 Screen Actors Guild Awards and the 2011 Grammy Awards. Boeing, the San Francisco International Airport and Paramount Pictures will soon be deploying units as well.
In addition to the DOE’s sponsorship and Sandia’s design and technical management role, the industry partners on the project include Boeing, Multiquip Inc., Altergy Systems, Luxim Corp., Lumenworks Inc., Stray Light Optical Technologies, Golden State Energy and Ovonic Hydrogen Solutions. The California Fuel Cell Partnership has provided support on hydrogen fuel for several deployments. Multiquip is implementing a manufacturing and commercialization plan for the system.
Sandia National Laboratories is a multiprogram laboratory operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy’s National Nuclear Security Administration. With main facilities in Albuquerque, N.M., and Livermore, Calif., Sandia has major R&D responsibilities in national security, energy and environmental technologies, and economic competitiveness.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
