Researchers create super-efficient microbial fuel cell, dream of selling excess electricity
Recycling wastewater to generate energy has turned up noses before, but researchers at Oregon State University have developed a microbial fuel cell that can create 10 to 50, or even 100 times more electricity per volume than similar technologies. After refining the tech for several years using new materials, techniques and selecting better microbes, the team can now extract two kilowatts per cubic meter of refuse. As bacteria oxidizes organic matter, electrons -- rather than the hydrogen or methane that other methods rely upon -- are produced and run from an anode to a cathode within the device to create an electric current. Once implementation costs are cut down, the technology could power waste treatment plants and enable them to sell excess electricity. The contraption isn't just for processing what comes out of the porcelain throne -- it can also utilize materials ranging from grass straw to beer brewing byproducts. For now, however, the cell will tackle a pilot study before it inches closer to your local brewery or water treatment facility.

High-energy laser fusion experiments evoke extreme numbers -- not only in power but also in greenbacks. Sure, the current champ at the National Ignition facility in Livermore, CA can pump out a 411 trillion watt pulse, but at what price? A taxpayer-busting $200,000 per shot, with a $4 billion original construction cost. Compared to that, the new Ohio State University's 500 trillion watt model seems bargain-basement, built with a mere $6 million grant from the US Department of Energy. Admittedly, that paltry sum get you a much shorter burst, lasting 20 picoseconds compared to the NIF's several nanoseconds. But with the ability to fire 100 or more times per day, instead of just once like it's pricier kin, Ohio State will be able to assist the NIF with their fusion experiments, while also carrying on its own science, like simulating star formation. And money aside, the possibility of unlimited fusion-powered energy is always a noble goal, no?
