Several teams made it to the 200 ft top of the tether climbing competition. The University of Saskatchewan space Design team got to the top the fastest in 58 seconds which is what was needed to win the competition. There is a question of whether they got down within the 2 minute time allowed. Congratulations …
As pointed out to me by Kirk Sorenson of Thorium Energy Review 1 of Big Coal by Jeff Goodell the American Lung Association estimates that 27,000 people a year still die prematurely as a result of pollution from coal-fired power plants. Coal-fired power plants are also the largest emitters of mercury in the United States, …
Time Magazine recently wrote about the bright future of coal energy The world used 4.6 billion tons of coal in 2004 and this amount is increasing. Global consumption of electricity is expected to double between 2002 and 2030. Global photovoltaic (solar) production is 1.7 GW in 2005. It is growing at 45% per year.We added …
Prototype invisibility cloak versus microwaves has been created Researchers first fired microwaves at a copper cylinder and recorded the electronic shadow it cast. They next showed in contrast that microwaves largely pass around the invisibility cloak as if it weren’t there. “There is some reflection, so this isn’t perfect, but it is only a prototype,” …
From defensetech, the Air Force is two Falcon Hypersonic Test Vehicles, built by Lockheed Martin with input from NASA and the Defense Advanced Research Projects Agency (Darpa), will take to the air in 2008. The $100-million program aims to field a Mach-10 unmanned aircraft that can spy on foreign powers, drop bombs or even lob …
The new therapy developed by the team from Yonsei University uses a genetically-engineered form of the adenovirus, which normally causes colds. Following three rounds of injections, more than 90 percent of cancer cells in the brains, liver, lungs and womb of mice disappeared within 60 days, the team said. Clinical tests will be carried out …
They demonstrated a method for refining entangled atom pairs (a process called purification) so they can be more useful in quantum computers and communications systems, emerging technologies that exploit the unusual rules of quantum physics for pioneering applications such as “unbreakable” data encryption. The reported purification rate is a record (although the entangled state is …
Hopefully it can work well and at or near the costs that they envision. From wired, when wind hits the KiteGen, kites spring from funnels at the ends of poles. For each kite, winches release a pair of high-resistance cables to control direction and angle. The kites are light and ultra-resistant, capable of reaching an …
A couple of other comments that I made on the greenpeace site. Re-edited.The comments were in reference to information at links pointed to by the Greenpeace person.End the nuclear age campaign. Talks about why Greenpeace is against nuclear power. they think plants are unsafe, nuclear waste problems and nuclear proliferation.However, the current and past real …
In contrast to extensive studies with several conventional semiconductors, such as gallium arsenide and indium arsenide, which can be made magnetic by adding magnetic impurities or by growing them next to standard ferromagnets, no such advances have yet been realized with silicon. Currently, even basic spintronic elements, such as reliable spin injection — ensuring that …
This could lead to better utilization of superconducting wires and the ability to get enhanced superconducting characteristics. From physorg.com, Superconducting wires are used in magnetic resonance imaging machines, high-speed magnetic-levitation trains, and in sensitive devices that detect variations in the magnetic field of a brain. Eventually, ultra-narrow superconducting wires might be used in power lines …
