A camera that powers itself!
New York NY (SPX) Apr 16, 2015 -
A research team led by Shree K. Nayar, T.C. Chang Professor of Computer Science at Columbia Engineering, has invented a prototype video camera that is the first to be fully self-powered--it can produce an image each second, indefinitely, of a well-lit indoor scene. They designed a pixel that can not only measure incident light but also convert the incident light into electric power.
The te ...

Quantization of 'surface Dirac states' could lead to exotic applications
Tokyo, Japan (SPX) Apr 16, 2015 -
Researchers from the RIKEN Center for Emergent Matter Science in Japan have uncovered the first evidence of an unusual quantum phenomenon--the integer quantum Hall effect--in a new type of film, called a 3D topological insulator.
In doing this, they demonstrated that "surface Dirac states"--a particular form of massless electrons--are quantized in these materials, meaning that they only ta ...

New 'cool roof time machine' will accelerate cool roof deployment
Berkeley CA (SPX) Apr 16, 2015 -
Cool roofs can help keep buildings cool, thus lowering the building's energy use, while also mitigating the urban heat island effect by reflecting sunlight away from buildings and cities. But as cool roofs age and get soiled, how much of their reflectance do they lose?
A collaboration led by scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) has established a method to simu ...

Packing heat: New fluid makes untapped geothermal energy cleaner
Richland WA (SPX) Apr 16, 2015 -
More American homes could be powered by the earth's natural underground heat with a new, nontoxic and potentially recyclable liquid that is expected to use half as much water as other fluids used to tap into otherwise unreachable geothermal hot spots.
The fluid might be a boon to a new approach to geothermal power called enhanced geothermal systems. These systems pump fluids underground, a ...

Harvesting energy from electromagnetic waves
Washington DC (SPX) Apr 16, 2015 -
For our modern, technologically-advanced society, in which technology has become the solution to a myriad of challenges, energy is critical not only for growth but also, more importantly, survival. The sun is an abundant and practically infinite source of energy, so researchers around the world are racing to create novel approaches to "harvest" clean energy from the sun or transfer that energy t ...
