Electric Cars: Drivers Love 'Em, So Why Are Sales Still Low? 810

Posted by timothy from the opportunity-cost dept.
cartechboy writes "The electric car challenge is what insiders call "getting butts in seats" — and a lot of butts today still belong to humans who are not yet buying electric cars. The big question is: Why? Surveys show drivers are interested in electric cars--and that they love them once they drive them. EVs also cost less to maintain (though more to buy in the first place) and many experts say they're simply nicer to drive. So what's the problem? Disinterested dealers, uneven distribution, limited supplies, and media bias are some potential challenges. Or maybe it's just lousy marketing--casting electric cars as a moral imperative or a duty, like medicine you have to take."

Another Casualty of Typhoon Haiyan: Geothermal Power 78

Posted by Soulskill from the thanks-bernoulli dept.
necro81 writes "Little known even in environmental circles is a renewable energy success story: five geothermal power plants on Leyte Island in the Philippines — each of which produces enough power for the entire island — that collectively produce more than 10% of the Philippines' total electrical demand. From boreholes deep underground comes pressurized water heated to 280 Celsius. At the surface it flashes into steam, turning one set of turbines, then cools and contracts to spin a second set of turbines. The low-grade steam is then condensed back into water and reinjected into the bedrock. But Typhoon Haiyan destroyed the cooling towers, snapped transmission towers, and scattered the employees."

A War Over Solar Power Is Raging Within the GOP 1030

Posted by Soulskill from the i-blame-the-sun dept.
mdsolar sends this quote from an article about the politics of solar energy: "Clean energy technology has always been an easy punching bag for conservatives. Propelled by growing strain of global warming denial within their party, Republicans in Congress have proposed to slash funding for renewable energy programs in half this year, and mocked the idea of a green economy as “groovy” liberal propaganda. Their argument, as laid out by House Republicans and libertarian organs like the Cato Institute and Reason magazine, is that the federal government shouldn't 'pick winners and losers' in the energy markets or gamble taxpayer dollars on renewable-energy loans to companies like Solyndra, the Silicon Valley solar panel manufacturer that went bankrupt in 2011 after receiving $535 million in federal loan guarantees. The assumption has always been that, without heavy government subsidies, renewable energy sources like solar and wind power would never be able to compete with fossil fuels. But something funny has happened to renewables that major power companies and their Republican allies didn't see coming. Over the past two years, the solar industry has skyrocketed, with one new solar unit installed every four minutes in the US, according to the renewable energy research group Greentech Media. The price of photovoltaic panels has fallen 62 percent since January 2011. Once considered a boutique energy source, solar power has become a cost-competitive alternative for many consumers, costing an average $143 per megawatt-hour, down from $236 in the beginning of 2011. Backed by powerful conservative groups, public utilities in several states are now pushing to curb the solar industry, and asking regulators to raise fees and impose new restrictions on solar customers. And as more people turn to rooftop solar as a way to reduce energy costs—90,000 businesses and homeowners installed panels last year, up 46 percent from 2011—the issue is pitting pro-utilities Republicans against this fledgling movement of libertarian-minded activists who see independent power generation as an individual right. In other words, the fight over solar power is raging within the GOP itself."

Elevation Plays a Role In Memory Error Rates 190

alphadogg writes "With memory, as with real estate, location matters. A group of researchers from AMD and the Department of Energy's Los Alamos National Laboratory have found that the altitude at which SRAM resides can influence how many random errors the memory produces. In a field study of two high-performance computers, the researchers found that L2 and L3 caches had more transient errors on the supercomputer located at a higher altitude, compared with the one closer to sea level. They attributed the disparity largely to lower air pressure and higher cosmic ray-induced neutron strikes. Strangely, higher elevation even led to more errors within a rack of servers, the researchers found. Their tests showed that memory modules on the top of a server rack had 20 percent more transient errors than those closer to the bottom of the rack. However, it's not clear what causes this smaller-scale effect."

Users Identified Through Typing, Mouse Movements 149

mask.of.sanity writes "Users can be identified with a half percent margin of error based on the way they type. The research work has been spun into an application that could continuously authenticate users (PDF), rather than just relying on passwords, and could lock accounts if another person jumped on the computer. Researchers are now integrating mouse movements and clicks, and mobile touch patterns into the work."

Researcher Shows How GPUs Make Terrific Network Monitors 67

Posted by samzenpus from the keeping-an-eye-on-things dept.
alphadogg writes "A network researcher at the U.S. Department of Energy's Fermi National Accelerator Laboratory has found a potential new use for graphics processing units — capturing data about network traffic in real time. GPU-based network monitors could be uniquely qualified to keep pace with all the traffic flowing through networks running at 10Gbps or more, said Fermilab's Wenji Wu. Wenji presented his work as part of a poster series of new research at the SC 2013 supercomputing conference this week in Denver."
