Ponca City, We love you writes "Temple University physics professor Rongjia Tao has developed a simple device that could dramatically improve fuel efficiency in automobiles by as much as 20 percent. The device, attached to the fuel line of a car's engine near the fuel injector, creates an electric field that thins fuel, reducing its viscosity so that smaller droplets are injected into the engine. Because combustion starts at the droplet surface, smaller droplets lead to cleaner and more efficient combustion. Six months of road testing in a diesel-powered Mercedes-Benz automobile showed an increase from 32 miles per gallon to 38 mpg, a 20 percent boost, and a 12-15 percent gain in city driving. 'We expect the device will have wide applications on all types of internal combustion engines, present ones and future ones,' Tao wrote in the study published in Energy & Fuels. 'This discovery promises to significantly improve fuel efficiency in all types of internal combustion engine powered vehicles and at the same time will have far-reaching effects in reducing pollution of our environment,' says Larry F. Lemanski, Senior Vice President for Research and Strategic Initiatives at Temple."

sethawoolley writes "In light of the upcoming elections in the US, author William Poundstone was interviewed about voting systems by Mother Jones. In it he advocates the benefits of Range Voting as a solution to Arrow's Impossibility Theorem. Approval, Borda, Instant Runoff, and Condorcet Voting, which are often solutions advocated by the Greens and Libertarians (in the US), are discussed, as well, in light of Warren Smith's recent empirical research using Bayesian Regret. My local party (of which I'm the Parliamentarian) uses Single Transferable voting, but we're considering using Range Voting in the future. One thing is for certain: any system is better than the West's out-dated plurality voting system."

marksilverman writes "Steven Levy at Newsweek is reporting that his iPod Shuffle seems to favor certain songs. Is Apple receiving kickbacks to promote certain artists? Apple denies it, of course, and Levy had the good sense to ask a mathmatician and a cryptographer who explained that it's probably just humans finding patterns where there are none." Less neurotically, both CNet and PCWorld have discussions of the Shuffle's interior spaces.
