Professor Klaus Lackner, Ewing-Worzel Professor of Geophysics in the Department of Earth and Environmental Engineering at Columbia University have developed a sorbent that is “close to the ideal,” in that it uses a relatively small amount of energy to release the CO2 and is not prohibitively expensive. “By the time we make liquid CO2 we …
Applications which can use the large new supply of carbon nanotubes [click on the picture to the left for a larger image]. CNano Technology (CNano) announced today at NT09: Tenth International Conference on the Science and Application of Nanotubes, that it has successfully scaled up its manufacturing technology to reach the world’s largest production capacity …
Semiconductor nanocrystals that can be readily mass-produced and retain efficient electrical conductance, which can be used for device manufacturing via inkjet printing and other solution-based processes. This makes them an attractive alternative to the large semiconductor crystals typically used in commercial solar cells and computer chips which are expensive and can make large-scale applications such …
Photos of one of the freight Maglev project in China.Linear Synchronous Motor Module. Shown with cover plate on the right. (January 2009) Completed capsule set for the Baotou demonstration system on the left. (October 2008) This is a follow up to the article on China’s pilot use of this technology for transporting coal. These are …
Starts with a Bang hosts the 108th Carnival of Space. This site contributed two articles. One was on the blast wave accelerator launcher which could launch high gravity hardened payloads for $200-2000/kilogram. and another article a nuclear thermal rocket variant (nuclear DC-X) for launching payloads for $85-150/kilogram. Centauri dreams looks at technology for mimicking volcanoes …
UPDATE: Follow up with more pictures of the Magplane pipeline work in progress in China and the proposed system for passenger transportation. END OF UPDATE China is installing two prototype magnetically levitated (maglev) systems for transporting coal in Inner Mongolia in an attempt to increase transport speeds and efficiencies, and to reduce pollution. Cost studies …
Here is an interview with NVIDIA’s Sumit Gupta. Dr. Gupta is a senior product manager with the NVIDIA Tesla GPU Computing Group. NVIDIA is heavily pushing GPU computing, and the field is expanding exponentially. There is an average of 10x-50x improvement using GPUs instead of CPUs, and they are finding that increasing numbers of applications …
Pike Research projects the global biodiesel and ethanol markets will reach $247 billion in sales by 2020, up from $76 billion in 2010. They see three key waves of biodiesel development over the next several years: * Fuels based on waste greases will reach market in 2010. * Jatropha-based fuels will begin having a significant …
Mice that were engineered with a fat-burning pathway borrowed from bacteria (top) remained thin compared with normal mice (bottom) when both were fed a high-fat diet.Credit: Jason Dean, University of California, Los Angeles This is transgenic metabolism transfer. They take the metabolism of bacteria and plants and transferred [maybe re-activated dormant genes] it to mice. …
Two patients with inoperable prostate cancer have made dramatic recoveries after receiving one dose of an experimental drug that is creating excitement among cancer specialists. The results were so startling that researchers decided to release details of the two cases before the drug trial – in which the patients took part – was complete. Doctors …
Three direct cycle designs [steam indirect cycle, helium direct, supercritical CO2]were selected for further investigation: the basic design with turbine inlet temperature of 550P o PC, an advanced design with turbine inlet temperature of 650P o PC and a high-performance design with turbine inlet temperature of 700P o PC, all with the compressor outlet pressure …
