NEI – UPDATE AS OF 11:20 A.M. EDT, FRIDAY, MARCH 18: Reactors 1, 2 and 3 at the Fukushima Daiichi nuclear power plant are in stable condition, with workers continuing to provide seawater cooling into the reactors. Containment integrity is believed to be intact on reactors 1, 2 and 3, and containment building pressures are …
The Accelerated Precision Mortar Initiative (APMI) has developed GPS guided mortars Current conventional mortar rounds used by the army only have an accuracy of about a 136 meter (446 ft) Circular Area Probable (CEP). This means that 50 percent of rounds will land within 136 m of the target, 43 percent will land between 136 …
Sandia’s machine was dismantled in July 2006 for an upgrade, including the installation of newly designed hardware and components and more powerful Marx generators. The refurbishment was completed in October 2007. The newer Z machine can now shoot 27 million amperes (instead of 18 million amperes previously) in 95 nanoseconds. The radiated power has been …
Unlike traditional emergency systems, called a tractor design by engineers, SpaceX wants to build an integrated launch abort rocket to provide escape capability throughout the rocket’s flight to orbit. Tractor designs used by the U.S. Mercury and Apollo programs were thrown away a few minutes after liftoff, as soon as their boosters cleared the atmosphere. …
BP has a projection of world energy usage until 2030 The BP projection can be compared to the comedic proposal by Stanford’s Mark Jacobson to shift to energy generation that only uses wind, solar, hydro and geothermal. Details of this fantasy are below BP projection The growth of oil in transport slows even more dramatically, …

Abundance (atom fraction) of the chemical elements in Earth’s upper continental crust as a function of atomic number. The rarest elements in the crust (shown in yellow) are not the heaviest, but are rather the siderophile (iron-loving) elements in the Goldschmidt classification of elements. These have been depleted by being relocated deeper into the Earth’s …
ACS Nano – High-Power Supercapacitor Electrodes from Single-Walled Carbon Nanohorn/Nanotube Composite A novel composite is presented as a supercapacitor electrode with a high maximum power rating (990 kW/kg; 396 kW/l) exceeding power performances of other electrodes. The high-power capability of the electrode stemmed from its unique meso-macro pore structure engineered through the utilization of single-walled …

Ground breaking for the two units, in Gujarat state, began in January 2010 and excavation works and other preparatory site works were completed by August, …
Wall Street Journal – China’s market share of manufacturing of advanced machinery could climb to 30% of global exports within the decade, from 8% today The progression of China’s rail business reflects a national economic strategy of boosting state-owned firms and obtaining advanced technology, even at the expense of foreign partners. Chinese rail companies that …
Ad Support : Nano Technology Netbook Technology News Computer Software Curved, twisted and overhanging microscopic structures have been made by US researchers from carbon nanotubes by exploiting capillary action. The technique can be used to make patterns of multiple different shapes at the same time and opens up new possibilities for tunable surfaces. John Hart and …
