According to the Carnegie Mellon study

For example, the amount of carbon dioxide emissions from a desktop computer in China generates up to three times higher than when the same desktop computer is to be manufactured in the U .S., according to the Carnegie Mellon study. Overall, the authors estimate that the CO2 emissions associated with imports, from 12 % of total U.S. Emissions in 1997 to 22 % in 2004, a significant increase in increased given that the U.S. Is already emitted about 25 % of the world total global carbon dioxide. These emissions are only going greenhouse gas emissions. Continues to increase, more and more essential goods by consuming beyond its borders, said Matthews, associate professor in the departments of civil and environmental engineering and engineering and public policy. And because the U.S. Continues to more goods from carbon – intensive trading partners to import, the researchers conclude, this trend in the short term in the short term, without major efforts to increase efficiency and cleaner development in emerging Weber and Matthews urge the U.S. And other developed countries to agree to a further reduction of greenhouse gas. A magnetic storage surface – the disk of a hard disk drive – consists of tiny areas of Magneti-cally aligned particles. When the read-write head of a hard drive is about a sector four, or fivees the magnetic field in the opposite direction – encoding a zero or a one. When he reads, she senses the magnetic field for the entire industry. To pack more information into a smaller area, engineers can make the particles smaller or the sectors smaller, but they need enough particles so that not ruin the occasional random flip the whole sector. It is now possible, magnetic nanoparticles with a thin, dense layer to be applied, but tend the magnetic fields of randomly oriented spherical particles to neutralize each other -. Instead of lining up to six or twelve clock, many particles align at two, four, or five, diluting the overall strength of the magnetic signal.
