+ - Engineers Unveil First Casimir Chip That Exploits The Vacuum Energy->

Submitted by theguyfromsaturn
theguyfromsaturn (802938) writes "The Physics arXiv reports on an interesting advance regarding the Casimir effect:

One of the most interesting effect arising from the quantum nature of the universe is the Casimir effect. The force can pull two conducting plates together when they are a few nanometers appart. This imposes limits on microelectromechanical machines due to the stiction arising between components. However several theories predict that the force should be repulsive between objects of certain shapes. Until now however, Casimir force experiments are extremely hard to do.

Jie Zou and others at the University of Florida have carved a single device out of silicon that is capable of measuring the Casimir force between a pair of parallel silicon beams, the first on-chip device capable of doing this.

Who knows, might be the first step into Poul Anderson's starfarers concepts (I kid)."

+ - Longest Tunnel Between Siberia & Alaska Planne->

Submitted by theguyfromsaturn
theguyfromsaturn (802938) writes "It seems that Russia is planning to build the world's longest tunnel, a transport and pipeline link connecting Siberia and Alaska. It is part of a $65 000 000 000 dollar project to supply the U.S. with oil, natural gas an electricity from Siberia. If the plan is accepted, Russia and the U.S. may each eventually take 25% stakes with private investors and international fincance agencies as other shareholders. The undersea tunnel would contain a high-speed railway, highway and pipelines, as well as power and fiber-optic cables. At 64 miles, the planned tunnel would be twice as long as the underwater section of teh Channel Tunnel between the U.K. and France, and would lik the two islands in the Bering Strait between Russia and the U.S. Note to Editor: In my previous submission I had forgotten the link. (lack of practice submitting)"
