...Meanwhile, some independent Russian and foreign experts believe that the explosion resulted from a malfunction in a practice torpedo's engine, propelled with concentrated hydrogen peroxide fuel, or HTP. Accidentally leaked HTP could have come in contact with silver or other metals present in the alloys used in submarine-building, they say, potentially resulting in a powerful explosion. This blast could then have detonated all or some of the Kursk's other torpedoes, causing the second powerful explosion that actually sank the state-of-the art nuclear cruiser a year...
...unemployment claims, reported Thursday, may be leveling off, and the August-centered effect of those magical tax rebate checks hasn?t had a chance to show up on the radar screen. And GM?s other utterance this week - about their success with free-standing stationery hydrogen fuel cells - suddenly got people thinking about a smog-less, grid-less energy future. Or at least a promising new thing for manufacturing to manufacture...
...Japan is applying the same approach as it seeks to develop ultra-efficient green cars. The government instituted a goal to make 100% of its fleet of 7,000 official cars "green," meaning they get ultrahigh mileage running, at least in part, on some ultra-clean fuel such as hydrogen. When told in May that this would take seven years, Prime Minister Junichiro Koizumi responded with "That's too long--make it three!" Denmark, Italy, Spain, Portugal, Greece, Austria and Sweden also use government purchases to stimulate production of renewables. By contrast, the U.S. has no comparable federal policies...
...characteristic sizes and also the temperatures, to a millionth of a degree, of these warm and cool regions gives theoretical physicists all sorts of information about the newborn cosmos. They were already pretty sure, from the equations of nuclear physics and from measurements of the relative amounts of hydrogen, helium and lithium in the universe, that protons, neutrons and electrons (the building blocks of every atom in the cosmos) add up to only about 5% of the so-called critical density--what it would take to bring the cosmic expansion essentially to a halt by means of gravity...
...help illustrate forensic science in action, the ExperiMentors volunteers decided to script a kidnapping that the students would then spend the day unraveling. Dolan was followed on stage by a guest lecturer who mysteriously disappeared after volunteers lit several hydrogen balloons on fire. The explosion, a laser light show and Mission Impossible theme music indicated to the crowd that the guest lecturer was the victim of a kidnapping and the students were now charged with her recovery...
