Standards needed to tap smart grid potential News & Analysis 2/25/2009 Post a comment The move to so-called smart electric grids will open new opportunities for communications companies in the energy sector, but it will require new standards, according to Jake MacLeod, chief technology officer with Bechtel Communications.
Study: U.S. photovoltaic costs declining News & Analysis 2/19/2009 Post a comment The installed costs of solar photovoltaic power systems in the U.S. declined significantly between 1998 and 2005, but remained relatively flat from 2006 through 2007, according to the results of a study conducted by the U.S. Department of Energy's Lawrence Berkeley National Laboratory.
Stimulus: DoE readies $4.3 billion for smart grid Product News 2/18/2009 Post a comment The U.S. Department of Energy has 60 days to set up a competitive process to award an estimated $4.3 billion for projects that will upgrade the nation's electric grid as one of the top clean technology provisions of the $787 billion economic stimulus package signed by President Barack Obama.
Video: Computer science meets the grid News & Analysis 2/13/2009 Post a comment Tomorrow's computers need to be designed to meet the energy efficiency needs of growing data centers and the power grid needs to evolve to be more like the Internet, according to Randy Katz, a professor of computer science speaking at an annual gathering of researchers from the University of California at Berkeley.
Video: Startup's founder describes 'black silicon' Product News 2/5/2009 Post a comment James Carey, co-founder of SiOnyx, talks about "black silicon," a material he developed that boasts more than 100 times the sensitivity of silicon, detects energy from the ultraviolet to the short-wave infrared bands, operates at a low voltage bias and, at less than 0.5 micron, is extremely thin.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
