Many industries use heat-intensive processes that generally require the burning of fossil fuels, but a surprising green fuel alternative is emerging in the form of metal powders. Ground very fine, cheap iron powder burns readily at high temperatures, releasing energy as it oxidises in a process that emits no carbon and produces easily collectable rust, or iron oxide, as its only emission. If burning metal powder as fuel sounds strange, the next part of the process will be even more surprising. That rust can be regenerated straight back into iron powder with the application of electricity, and if you do...

Jan. 28, 2004--Earlier today, Citizens for Responsibility and Ethics in Washington, a non-profit legal watchdog group, sent a letter to President Bush asking that he call upon the White House Counsel to investigate Vice President Cheney's confirmation of leaked classified information in an interview with the Rocky Mountain News on January 9, 2004. Federal law prohibits leaking classified information. Confirming information that has already been leaked is also prohibited. In his Jan. 9th interview, Mr. Cheney referred his interviewer to a story that appeared in The Weekly Standard's November 24, 2003 issue. The story, written by Stephen F. Hayes, discussed...

Scientists levitate gold coins Scientists have shown that levitation is not just a trick from a Harry Potter book. Researchers at the University of Nottingham have used magnetism to make solid objects such as coins float in the air. Scientists have already proven strong, varying magnetic fields could exert an upward force on objects in their path. The Nottingham team found this effect could be dramatically enhanced in cold, magnetised oxygen. Magnetic levitation occurs when the magnetic force is strong enough to overcome gravity and balance a body's weight. Cold oxygen provides extra buoyancy through the "magneto-Archimedes" effect -...
