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.
Smart Grid Technology: Vulnerable To Hackers
Interaction of tailored light with a single atom and individual nanostructures
By adapting a mode of the light field to a system under study, the interaction of light with matter can be optimized. In this context, the spatial distribution of the electric field of such a tailored mode ...
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.
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 ...
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.
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 ...
'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.
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.
Where's the next boom? Maybe in 'cleantech'
(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 ...
Energy transition project moves into its second phase
Siemens is studying new concepts for optimizing the cost-effectiveness and technical performance of energy systems with distributed and fluctuating electricity production. The associated IRENE research project ...
Precision irrigation for ornamental plant
A prototype of precise irrigation system tested in Italy for ornamental plants nurseries as water shortage puts pressure on growers
Getting the most out of home electricity
Large household appliances, such as refrigerators and washing machines, account for a huge amount of daily electricity consumption. An EU-funded project has developed a system to help you and your neighbours ...
