Fuel from methane hydrate

Popular Mechanics:

Carved from its surroundings, a chunk of methane hydrate looks like a hard-packed snowball--white, cold and solid. At room temperature, the resemblance fades as fast as snow itself, hissing and popping as it dissolves. Light a match and the difference is even starker: It burns. Studying this unstable substance is hardly easy. Even so, the team aboard the Integrated Ocean Drilling Program's (IODP) JOIDES Resolution is part of an international community determined to understand its many paradoxes.

"Thirty years ago, hydrates were a novelty," says Miriam Kastner, a professor at Scripps Institution of Oceanography and a geochemist on the IODP expedition last fall. "We didn't realize their significance, and no one calculated how much there could be." Then someone began to do the math. Methane bound in hydrates could provide the world with an astounding amount of natural gas--if it could be safely extracted. If released inadvertently, it could cause untold damage: hastening global warming and kick-starting tsunamis by causing seafloor slumping.

On the other hand, sea floor slumping could help displace sea level heights casued by melting ice.
