Affordable Chip Pinpoints Methane Leaks

One of today’s most affordable sources of fossil-based energy is natural gas, which consists primarily of methane. Found in remote, deep underground reservoirs, the gas must be transported through long pipelines with thousands of connections, valves and pumping stations, which are inevitably prone to leaks. Scientists at IBM are testing a small, affordable gas detector that could be placed literally anywhere. VOA’s George Putic reports.
