Japan eyes ethanol to cut greenhouse gas emissions
: Ethanol-blended petrol is already used for cars in Brazil, the United States, Canada and Sweden. Argentina, Australia, India, Thailand, and China are preparing to use the blend... An ethanol blending ratio of 10 percent is common in the United States, the second largest producer and consumer of ethanol. It produces the fuel from corn.
In Brazil, the top ethanol producer and consumer, the level of sugarcane-based ethanol in the nation's gasoline will rise to 24 percent in January from 22 percent now. The Japanese have not used ethanol as fuel... Mandatory use of ethanol as a fuel additive for cars in the same blending ratio as Brazil would reduce Japan's carbon dioxide emissions by about two percent... "Worldwide consumption of ethanol as fuel could more than double in the next several years," Mitsui's Okuda said 9:50:54 PM

Superconducting Metals Research Breaks The Law
: Scientific understanding of metals has until now been governed by the Wiedemann-Franz law. "Simply put, the rule generally was that a good conductor of heat was also a good conductor of electricity," says physics professor Louis Taillefer.. "But in these new copper oxide materials, the way the charge is conducted is completely unrelated to the way the heat is conducted, and that has a very large impact on how we understand these materials.. Once we gain a better understanding of how materials like these copper oxides work, it could open a window on a whole class of materials that have completely different sets of laws and properties" 4:04:18 PM
A solar power unit
that can be carried in a backpack is available from Solardyne
. It contains a folding monocrystalline solar panel, battery, controller, plugs, cords and light. It weighs 24 pounds, provides 120 watt-hours of power a day, powers AC and DC electronics up to 300 watts. It can be used in recreational vehicles as well as for field research, emergency home power, disaster relief and international aid, and sterilizing water with a UV light. After charging for six hours with the unit's solar photovoltaic panel, the Solar Power Pack can run a laptop computer for three hours or its own high-efficiency light for 14 hours. It sells for $549. The solar panel is designed to last 20 years. The battery lasts for 600 charge cycles, which equals about two years if the system is used daily. Once spent, the battery can be replaced and recycled. 12:00:03 AM
