Yes, definitely a potential resource - and also a potent greenhouse gas if allowed to escape into the atmosphere - probably a much better reason to burn it than the fuel saving itself. Probably very limited amounts produced in natural environment compared with heaps of composting material, landfill sites etc.
Someone posted a Youtube clip a short while ago on methane accumulating under lake icesheets - someone bored a hole and lit the gas - enough to cook your lunch on! Someone else with better memory will probably point to the link.
Dr Ian Stewart, Volcanologist, on a recent prog when he visited the Siberian tundra where the permafrost is now melting and apart from revealing a host of dinosaur bones is also releasing vast amounts of previously trapped methane.
