RoboClam anchor based on sea creature

Inspired by the way razor clams dig into the seafloor sediment, MIT researchers have built a robotic anchor for autonomous water vehicles. About the size of a cigarette lighter, the prototype RoboClam imitates the way the real clam's "foot" works its way into the sand. — Read the rest

Cow waste for power

Researchers from Ohio State University have shown that the fermented, liquefied feed extracted from a cow's stomach can produce about 600 millivolts. The juice comes from the rumen, the biggest portion of a cow's stomach. Unlike converting methane from cow shit into electricity, a method that requires expensive gear, this method generates electricity as the microorganisms in rumen fluid break down the complex carbohydrates in roughage. — Read the rest
