DEEP in the Arctic Circle, in the Messoyakha gas field of western Siberia, lies a mystery. Back in 1970, Russian engineers began pumping natural gas from beneath the permafrost and piping it east across the tundra to the Norilsk metal smelter, the biggest industrial enterprise in the Arctic.
By the late 70s, they were on the brink of winding down the operation. According to their surveys, they had sapped nearly all the methane from the deposit. But despite their estimates, the gas just kept on coming. The field continues to power Norilsk today.
Where is this methane coming from? The Soviet geologists initially thought it was leaking from another deposit hidden beneath the first. But their experiments revealed the opposite - the mystery methane is seeping into the well from the icy permafrost above.
If unintentionally, what they had achieved was the first, and so far only, successful exploitation of methane clathrate. Made of molecules of methane trapped within ice crystals, this stuff looks like dirty ice and has the consistency of sorbet. Touch it with a lit match, though, and it bursts into flames……
The cure for a fallacious argument is a better argument, not the suppression of ideas.
