I was reading one of the logistics magazines I regularly get and found out something amazing. By about 2020, roughly 80 percent of the lift trucks in America will be powered by hydrogen fuel cells. The fuel cell advantage is constant voltage output and longer continuous run time. In addition, recharging time is short because […]

A new look at high-temperature superconductors
While the phenomenon of superconductivity — in which some materials lose all resistance to electric currents at extremely low temperatures — has been known for more than a century, the temperature at which it occurs has remained too low for any practical applications. The discovery of “high-temperature” superconductors in the 1980s — materials that could […]
Rethinking wind power
“People have often thought there’s no upper bound for wind power—that it’s one of the most scalable power sources,” says Harvard applied physicist David Keith. After all, gusts and breezes don’t seem likely to “run out” on a global scale in the way oil wells might run dry. Yet the latest research in mesoscale atmospheric […]
Laser mastery narrows down sources of superconductivity
Identifying the mysterious mechanism underlying high-temperature superconductivity (HTS) remains one of the most important and tantalizing puzzles in physics. This remarkable phenomenon allows electric current to pass with perfect efficiency through materials chilled to subzero temperatures, and it may play an essential role in revolutionizing the entire electricity chain, from generation to transmission and grid-scale […]
QFP socket operates at bandwidths up to 10 GHz with less than 1dB of insertion loss
Ironwood Electronics has recently introduced a new high performance QFP socket for 0.4mm pitch 128 pin QFP. The SG-QFE-7011 socket is designed for 14mm x 14mm x 1.6mm package size with 16mmx16mm lead tip to tip and operates at bandwidths up to 10 GHz with less than 1dB of insertion loss. The contact resistance […]
Fanless medical computer features rich I/O connectivity and wireless support
ADLINK Technology announces the first of its new TOPAZ line of medical computers, the 3rd edition of EN-60601-1 certified TPZ-1300, featuring rich I/O connectivity, wireless support, and duty-specific performance processors with long life support. The TPZ-1300 delivers ruggedized reliability, making it ideal for mobile functionality in environments such as telemedicine, NIS (nursing information systems), and […]
Pentagon stands by use of lithium-ion batteries on F-35 fighters
(Reuters) – The Pentagon said it plans to continue using lithium-ion batteries on the new F-35 fighter jet despite problems with similar batteries that have grounded Boeing Co’s new 787 airliner and are causing Airbus to rethink their use on its A350 jet. Joe DellaVedova, spokesman for the Pentagon’s $396 billion F-35 program office, said […]
Full Comcast ownership is latest chapter in long history for broadcasting pioneer NBC
NEW YORK (AP) — NBC got its start in 1926 as the nation’s first radio network. Its parent company, the Radio Corporation of America, figured people would buy radios if they had interesting things to listen to. NBC was the leading radio network in the early years, so powerful in those days that it had […]
High-tech airship under construction in California hangar could provide cargo solutions
TUSTIN, Calif. (AP) — The massive blimp-like aircraft flies but just barely, hovering only a dozen feet off a military hangar floor during flight testing south of Los Angeles. Still, the fact that the hulking Aeroscraft could fly for just a few minutes represents a step forward in aviation, according to the engineers who developed […]
ORNL research paves way for larger, safer lithium ion batteries
OAK RIDGE, Tenn., Jan. 23, 2013 — Looking toward improved batteries for charging electric cars and storing energy from renewable but intermittent solar and wind, scientists at Oak Ridge National Laboratory have developed the first high-performance, nanostructured solid electrolyte for more energy-dense lithium ion batteries. Today’s lithium-ion batteries rely on a liquid electrolyte, the material […]
