Power/Performance Bits: June 13


Theoretical all-carbon circuits Engineers at the University of Texas at Dallas, the University of Illinois at Urbana-Champaign, the University of Central Florida, and Northwestern University designed a novel computing system made solely from carbon. "The concept brings together an assortment of existing nanoscale technologies and combines them in a new way," said Dr. Joseph S. Friedman, ass... » read more

Power/Performance Bits: Nov. 29


PV technology comparison Joshua J. Romero at the IEEE Spectrum put together an overview of photovoltaic technologies, including the world records for each type of cell, grouped into five broad categories. There is a brief overview of each cell type and some of its trade-offs. He also looks at how fast each technology has made efficiency gains. The most rapid progress is being seen in high... » read more

Power/Performance Bits: June 10


Cheaper, lighter solar cells Think those flat, glassy solar panels on your neighbor’s roof are the best solar technology has to offer? Not so. Engineers in the University of Toronto’s Department of Electrical & Computer Engineering have designed and tested a new class of solar-sensitive nanoparticle that they say outperforms the current state of the art. Based on a new form of solid... » read more
