Cow flatulence may someday have a new scent: money. Palo Alto, Calif.-based Bluefield Technologies plans to launch a fleet of satellites that can detect methane emissions, a technology that has the potential to catch leaks at oil and gas facilities or monitor climate-change commitments by nations. The most immediate use, though, might be for commodity traders tracking the supply of cattle. Microbes in a cow's stomach produce methane as they break down food, which is then released in manure, burps and flatulence. Measuring levels of the gas can indicate the size of herds in areas where shelters block visual checks, such as dairy farms or feedlots, said Yotam Ariel, Bluefield's founder and chief executive officer.
