The Battery Problem


The fires sweeping the West Coast of the United States point to the need for a whole different way of managing power on both a macro and a micro level. Since the millennium, the power demand from data centers and from mobile devices has been climbing steadily. There are roughly 7.8 billion people on the planet, up from 6.115 billion people in 2000, according to the World Bank. Many of them o... » read more

5 Major Shifts In Automotive


Much of the automotive industry has begun repositioning and retrenching over the past few months, pushing back the projected rollout for fully autonomous vehicles and changing direction on power sources and technology used in the next-generation of electric vehicles. Taken together, these shifts mark a significant departure for traditional automakers, which find themselves playing catch-up t... » read more

Power/Performance Bits: March 21


Tiny redox flow batteries for chips Researchers at ETH Zurich and IBM Research Zurich built a tiny redox flow battery capable of both powering and cooling stacks of chips. In a flow battery, an electrochemical reaction is used to produce electricity out of two liquid electrolytes, which are pumped to the battery cell from outside via a closed electrolyte loop. Such batteries are usually u... » read more

Power/Performance Bits: Aug. 23


Connecting implanted devices University of Washington researchers developed a new method for communication between devices such as brain implants, contact lenses, credit cards and smaller wearable electronics with other devices such as smartphones and watches. Using only reflections, an interscatter system requires no specialized equipment, relying solely on mobile devices to generate Wi-... » read more
