When methane and freezing cold water fuse under tremendous pressure, they create a substance as paradoxical as it coveted: burning ice. Earlier in the year, a report from the National Research Council identified the combustible water, also known as methane hydrate, as a potential source of natural gas.
Gas hydrates could produce more energy than all other fossil fuels combined. Alaska's got a giant stash of this alternative energy source beneath its north slope. Check out this comic to get the inside scoop.
