Innovative self-cooling, thermoelectric system developed

Spanish researchers at the UPNA/NUP-Public University of Navarre have produced a prototype of a self-cooling thermoelectric device that achieves "free" cooling of over 30ºC in devices that give off heat. It is a piece of ...

Fast, efficient switching – thanks to HiPoSwitch

Electrical power comes out of wall sockets, of course. But hardly any electronic device can take normal line voltage. Computers, smartphones, LEDs, and chargers, for instance, cannot use electrical energy in that form – ...

A world record in direct current transmission

Siemens is building power converter stations for a high-voltage direct current (HVDC) transmission system with a record capacity of 2 x 1,000 megawatts. Beginning in 2013 the new HVDC PLUS technology will transmit 2,000 megawatts ...

Novel technology to shrink laptop adapters to a quarter the size

While laptops continue to shrink in size and weight, the "power bricks" that charge them remain heavy and bulky. But now, MIT spinout FINsix has invented an adapter that's roughly one-quarter the size and one-sixth the weight ...

Researchers create novel photonic chip

Researchers at the George Washington University and University of California, Los Angeles, have developed and demonstrated for the first time a photonic digital to analog converter without leaving the optical domain. Such ...

A steady mobile power supply for Swiss trains

Siemens is stabilizing the power grid of the Swiss railroad company Schweizerische Bundesbahnen (SBB) by providing it with the world's first mobile units that compensate for reactive power. The overhead conductor, as well ...

CERN: The first accelerators are back in action

The CERN Control Centre is back in shift work mode, with walls of screens showing the status of the beams, and coffee flowing freely day and night. On Friday, 3 July, the Long Shutdown 2 accelerator coordination team handed ...
