The Cambridge-based hardware and software design company has recognised the established pool of RF design skills among the engineering workforce in the West Country and has chosen a location near Bath as the site of the new design centre

The 2008 Live EDGE Competition, which carries with it more than $100,000 in cash prizes, is open to electronic design engineers, inventors, hobbyists, and students.

“Two years ago customers didn’t want to pay 20 cents for lower power consumption. These customers are now very much in the minority and most demand products meet EnergyStar or other efficiency standard.”

These materials look very promising for high-efficiency reproducible organic solar cells, said Jef Poortmans, programme director

The aeroplane, called Zephyr, has a 20 metre wingspan but a mass of only 32kg thanks to its carbon fibre construction

Google has set a goal to produce one gigawatt of renewable energy capacity, enough to power a city the size of San Francisco, in a few years

Energy-saving DC-DC converter design must have two attributes - high efficiency over wide ranging load currents and low quiescent current in both standby and shutdown modes

Roy Allen provides an overview of the concepts required for successful paralleling of AC-DC front-end power supplies.

Operating reliably in extreme ambient temperatures is no small task for AC to DC power supplies with PFC, especially for indoor and outdoor-mounted equipment where compact size is mandatory.

Arizona-based CdTe solar cell firm First Solar expects to hit 12% efficiency in its thin film cells in the next four years.
