Want fuel cells? Think outside the hydrogen tank
(PhysOrg.com) -- When most people hear the words "fuel cell," they think of eco-friendly, hydrogen-powered cars that emit nothing more than water.
Wireless networks exposed as electricity grid weakest link
Smarter, more efficient electricity meters aim to revolutionise energy distribution but WA researchers fear hackers could easily exploit numerous security flaws and wreck havoc on power grids.
'Artificial leaf' eyed as holy grail in energy research
Turbo-charging photosynthesis -- by which plants and bacteria turn sunlight into food and energy -- in an "artificial leaf" could yield a vast commercial power source, scientists said.
Smart Grid Technology: Vulnerable To Hackers
'Distributed energy' has power to save billions
Wide-scale adoption of low-emission distributed energy could reduce the cost of transitioning to a low-carbon future by as much a $130 billion by 2050, according to a new report released today by CSIRO.
Smart software for self-regulating smart grid
Siemens and the utility company Allgauer Uberlandwerk (AUW) in the city of Kempten, Germany, are testing the smart grids of the future. The tests focus on optimized power distribution and the use of a self-organizing ...

(AP) -- Our economy sure could use the Next Big Thing. Something on the scale of railroads, automobiles or the Internet - the kind of breakthrough that emerges every so often and builds industries, generates ...
Global permafrost zones in high-resolution images on Google Earth
Thawing permafrost will have far-reaching ramifications for populated areas, infrastructure and ecosystems. A geographer from the University of Zurich reveals where it is important to confront the issue based ...
Observing impact of subtle changes in electron distribution of crystal on its atomic structure on ultrashort time scales
When a crystal is hit by an intense ultrashort light pulse, its atomic structure is set in motion. A team of scientists from the Max Planck Institute of Quantum Optics (MPQ), the Technischen Universität ...
Ageing wooden power poles increase risk of fires
Research at RMIT University has proven conclusively that wooden poles used for electricity distribution deteriorate with age and that their electrical performance worsens over time.
Combined cyber and physical security system for charging electric vehicles
As electricity grids become more sophisticated, grid administrators can collect instantaneous data on consumer and supplier behavior. The 'smart grid' then learns to improve the reliability, costs and sustainability of electricity ...
Adding renewable energy to power grid requires flexibility
Solar panels, wind turbines, electric vehicles and other green power sources are proliferating rapidly, but their reliable integration into the existing electric grid is another story.
