San Diego to become America's smartest city

San Diego to become America's smartest city

Feb 24, 2017
San Diego is affectionately known as America's finest city, but the Southern California metropolis will soon become America's smartest city.
Stabilising energy storage

Stabilising energy storage

Feb 24, 2017 United States
Because the sun doesn't always shine, solar utilities need a way to store extra charge for a rainy day. The same goes for wind power facilities, since the wind doesn't always blow. To take full advantage of renewable energy, electrical grids need large batteries that can store the power coming from wind and solar installations until it is needed.
Printable solar cells just got a little closer

Printable solar cells just got a little closer

Feb 24, 2017 Canada
This alternative solar technology could lead to low-cost, printable solar panels capable of turning nearly any surface into a power generator.
Next gen batteries could provide power to microsatellites, cubesats

Next gen batteries could provide power to microsatellites, cubesats

Feb 23, 2017 United States
The size of the battery is so thin (2-3 millimeters) that it is a prime candidate for use in microsatellites, including CubeSats.

Making sodium-ion batteries that last

Making sodium-ion batteries that last

Feb 21, 2017 United States
Lithium-ion batteries have become essential in everyday technology. But these power sources can explode under certain circumstances and are not ideal for grid-scale energy storage. Sodium-ion batteries are potentially a safer and less expensive alternative, but current versions don't last long enough yet for practical use.
Low-power chip could make speech recognition ubiquitous

Low-power chip could make speech recognition ubiquitous

Feb 21, 2017 United States
Whereas a cellphone running speech-recognition software might require about 1 watt of power, the new chip requires between 0.2 and 10 milliwatts, depending on the number of words it has to recognize.
