This one is different from the other projects in that it's not really exploiting processing power, but rather, built-in accelerometers in laptops as a distributed seismograph. The idea is to provide a better understanding of earthquakes, give early warning to schools, emergency response systems and others (a big emphasis of the project is getting K-12 science teachers involved). While desktop systems don't have accelerometers, they can be outfitted with USB-based sensors to partake in the network. The smallest earthquake detected by the network so far measured 3.1 in southern California and the largest has been a 6.4 in Japan. The project, which has about 1,000 sensors in action (though the number varies week to week), is the brainchild of researchers from the University of California, Riverside and Stanford University.
