The question one has to ask about this huge methane gas leak is this: Which is more obscene, the fact that it happened in the first place, or the lack of urgency by all levels of government in doing something about it?
Surly significant amounts could be siphoned off into, say, the rubber bladders the military uses to store and transport fuel in. And at the same time, portable turbines might be brought in to start liquefying as much as possible, burning the methane itself to power the cryogenic process? Even if you just shuttled the bladders to another power plant, or to a desalination plant to offset the power cost of creating potable water, you would be doing some good.
The bottom line here is ought to be that anything diverted from going directly into the atmosphere is better than nothing,
