All of this was called into question by the install notepad++ voyage of the Chikyu (“Earth”), a 0 million Japanese deep-sea drilling vessel that looks like a billionaire’s yacht with a 30-story oil derrick screwed into its back. The Chikyu, a floating barrage of superlatives, is the biggest, glitziest, most sophisticated research vessel ever constructed, and surely the only one with a landing pad for a 30-person helicopter. The central derrick houses an enormous floating drill with a six-mile “string” that has let the Chikyu delve deeper beneath the ocean floor than any other ship.
The Chikyu, which first set out in 2005, was initially intended to probe earthquake-generating zones in the planet’s mantle, a subject of obvious interest to seismically unstable Japan. Its present undertaking was, if possible, of even greater importance: trying to develop an energy source that could free not just Japan but much china post tracking india of the world from the dependence on Middle Eastern oil that has bedeviled politicians since Churchill’s day.
In the 1970s, geologists discovered crystalline natural gas—methane hydrate, in the jargon—beneath the seafloor. Stored mostly in broad, shallow layers on continental margins, methane hydrate exists in immense quantities; by some estimates, it is twice as abundant as all other fossil fuels combined. Despite its plenitude, gas hydrate was long subject to petroleum-industry skepticism. These deposits—water molecules laced into frigid cages that trap “guest molecules” of natural gas—are strikingly unlike conventional energy reserves. Ice you can set on fire! Who could take it seriously? But as petroleum prices soared, undersea-drilling technology improved, and geological surveys accumulated, interest rose around the world. The U.S. Department of Energy has been funding a methane-hydrate research program since 1982.
Nowhere has the interest been more serious than Japan. Unlike Britain and the United States, the Japanese failed to become “the owners, or at any rate, the controllers” of any significant amount of oil. (Not that Tokyo didn’t try: it bombed Pearl Harbor mainly to prevent the U.S. from blocking its attempted conquest of July 2018 Blank Calendar the oil-rich Dutch East Indies.) Today, Churchill’s nightmare has come true for Japan: it is a military and industrial power almost wholly dependent on foreign energy. It is the world’s third-biggest net importer of crude oil, the second-biggest importer of coal, and the biggest importer of liquefied natural gas. Not once has a Japanese politician expressed happiness at this state of affairs.
Japan’s methane-hydrate program began in 1995. Its scientists quickly focused on the Nankai Trough, about 200 miles southwest of Tokyo, an undersea earthquake zone where two pieces of the Earth’s crust jostle each other. Step by step, year by year, a state-owned enterprise now called the Japan Oil, Gas, and Metals National Corporation (JOGMEC) dug test wells, made measurements, and obtained samples of the hydrateTop Searches - Trending Searches - New Articles - Top Articles - Trending Articles - Featured Articles - Top Members
