British firm to build 'Africa's biggest solar plant'
British renewable energy firm Blue Energy announced Tuesday that it will build a giant solar power plant in Ghana which it claimed will become the biggest in Africa.
Scientists put a new spin on traditional information technology
Is it time for a communications paradigm shift? Scientists calculate that encoding and sending information via electron spin, instead of voltage changes, may mean tiny chips could transmit more information and consume less ...
Medical vital-sign monitoring reduced to the size of a postage stamp
Electrical engineers at Oregon State University have developed new technology to monitor medical vital signs, with sophisticated sensors so small and cheap they could fit onto a bandage, be manufactured in ...
A smarter way to make ultraviolet light beams
Existing coherent ultraviolet light sources are power hungry, bulky and expensive. University of Michigan researchers have found a better way to build compact ultraviolet sources with low power consumption ...
Memory device holds key to green gadgets
Fast, low-energy memory for MP3s, smartphones and cameras could become a reality thanks to University of Edinburgh scientists.
The impending revolution of low-power quantum computers
By 2017, quantum physics will help reduce the energy consumption of our computers and cellular phones by up to a factor of 100. For research and industry, the power consumption of transistors is a key issue. ...
Mini disks for data storage: Slanted edges favor tiny magnetic vortices
Slanted exterior edges on tiny magnetic disks could lead to a breakthrough in data processing. Materials researchers of the Helmholtz-Zentrum Dresden-Rossendorf, Germany, were able to create magnetic vortices with a diameter ...
Projection system barely larger than a grain of sugar
Lemoptix is developing an ultra-compact projector. The EPFL spin-off has already successfully entered a very competitive market, and will target new markets in 2014.
What's mine is virtually yours: Collaboration between mobile phone users can speed up communications
Applications on modern wireless devices make demands on data rate and connectivity far beyond anything experienced in the past. One way to meet these stringent requirements is to give the device multiple antennas or multiple-input ...
A bump circuit with flexible tuning ability that uses 500 times less power
A bump circuit with flexible tuning ability that uses 500 times less power and is smaller than previous circuits has been demonstrated by researchers at the University of Tennessee in the US.
A good tern deserves another: Low-power, remote monitoring of island birds cuts bills
The use of portable, wireless cameras and monitoring equipment for recording and transmitting footage of wildlife is perhaps familiar to anyone who watches nature programs on TV. However, common to all such equipment is the ...
