The 125-light test, due to launch this summer, will be implemented by hometown smart-grid company Echelon (ELON). The streetlight network will function in a similar way to a smart electricity grid. Using the city's wi-fi network, Echelon's networking technology enables the lights to transfer real-time data about the status and performance of any given bulb. That way, maintenance crews won't have to search for a fried bulb. The city will be able to monitor energy consumption, anticipate outages and dim lights to save energy at the flip of a master switch. Complete article.
A funny thing happened on the way to oblivion - for many scientists today, cold fusion is hot again. "We can yield the power of nuclear physics on a tabletop. The potential is unlimited. That is the most powerful energy source known to man," researcher Michael McKubre told 60 Minutes correspondent Scott Pelley. McKubre is an electro-chemist who imagines, in 20 years, the creation of a clean nuclear battery. "For example, a laptop would come pre-charged with all of the energy that you would ever intend to use. Watch the entire 60 Minutes story here.
