Energy harvesters transform waste into electricity

  • PDF
TechAndComputer (May 16, 2011) — Billions of dollars lost each year as waste heat from industrial processes can be converted into electricity with a technology being developed at the Department of Energy's Oak Ridge National Laboratory.

The high-efficiency thermal waste heat energy converter actively cools electronic devices, photovoltaic cells, computers and large waste heat-producing systems while generating electricity, according to Scott...

Beyond smart phones: Sensor network to make 'smart cities' envisioned

  • PDF
TechAndComputer (May 16, 2011) — Thanks to numerous sensors, Smartphones make it easy for their owners to organize certain parts of their lives. However, that is just the beginning. Darmstadt researchers envision entire "smart" cities, where all devices present within municipal areas are intelligently linked to one another.

Computer scientists, electrical and computer engineers, and mathemati­cians at the TU Darmstadt and the University of Kassel...

Toward faster transistors: Physicists discover physical phenomenon that could boost computers' clock speed

  • PDF
TechAndComputer (May 15, 2011) — In the 1980s and '90s, competition in the computer industry was all about "clock speed" -- how many megahertz, and ultimately gigahertz, a chip could boast. But clock speeds stalled out almost 10 years ago: Chips that run faster also run hotter, and with existing technology, there seems to be no way to increase clock speed without causing chips to overheat.

In this week's issue of the journal Science, MIT...

Super energy storage: Activated graphene makes superior supercapacitors for energy storage

  • PDF
TechAndComputer (May 13, 2011) — Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have helped to uncover the nanoscale structure of a novel form of carbon, contributing to an explanation of why this new material acts like a super-absorbent sponge when it comes to soaking up electric charge. The material, which was recently created at The University of Texas -- Austin, can be incorporated into "supercapacitor"...
