Wrap these chips around a hot steam pipe in a factory, or line the walls of a bakery with them, and you have electricity generated locally. The heat inside factories or bakeries is waste heat, or energy you bought but don't really use for a productive purpose. To add insult to injury, not only do you pay for this unproductive power, companies also have to put power into air conditioners to get rid of it. Scientists at Lawrence Berkeley Lab estimate that the U.S. consumes 100 quads (100 quadrillion BTUs) of energy a year and 55 to 60 quads get burned as waste heat. More>

Stimulus money designed to blunt the economic recession injected some much-needed funds into supercomputing programs around the world. In the US, the American Recovery and Reinvestment Act of 2009 (ARRA) is funding a range of new work, including a new climate research collaboration NOAA and ORNL ($73.5 million), the 100 Gbps ESnet upgrade for the DOE ($62 million), the Jaguar supercomputer upgrade at ORNL ($19.9 million), and the DOE's science cloud research project at Lawrence Berkeley and Argonne ($32 million). NASA and the NSF are also parceling out recovery money to HPC projects, generally in much smaller increments though. To date, NASA has spent $86 million, the NSF $92 Million, and DOE $1.58 billion of Recovery Act money, although only a portion of this is being applied to HPC. The good news is that this represents only a small fraction of the stimulus funds that are available to these agencies, so we can expect a lot more money to buoy the government and education segments in the coming years.

Imagine a "dream" agreement emerging from Copenhagen next week: The U.S. agrees to cut greenhouse emissions 80% by 2050, as President Barack Obama has been promising. The other developed countries promise to cut emissions by 60%. China promises to reduce its CO2 intensity by 70% in 2040. Emerging economies promise that in 2040, when their wealth per capita has grown to half that of the U.S., they will cut emissions by 80% over the following 40 years. And all parties make good on their pledges. Environmental success, right? Wrong. Even if the goals are all met, emissions will continue rising to nearly four times the current level. More>

Cyrus Wadia, co-director of Clean Tech to Market at the University of California's Haas School of Business and guest scientist at Lawrence Berkeley National Lab, is known worldwide for his activities in the development of new low-cost PV technologies using metal sulfides. He has given considerable thought to Moore's Law, as it might apply to PV. More>
