Flammable Ice: New Sustainable Energy Tech/Source for Japan?

On Tuesday, Japan became the first country to ever successfully extract natural gas from underwater deposits of methane hydrate, a frozen gas sometimes referred to as "flammable ice." The breakthrough could be a boon to the energy-poor nation, which imports almost all of its energy. And if the technology proves commercially viable, it could benefit other countries — including Canada, the U.S., Norway, and China — that are also seeking to exploit methane hydrate deposits.
