All the energy America needs for the next 100 years lies under the sea off the coast of South Carolina. One problem: Digging it out could cause a global climate disaster.

Welcome to the final frontier in fossil fuels, the wild card in climate change theories and the dark horse in the scramble to secure access to clean energy. Meet methane hydrates, the world's most promising and perilous energy resource.

Engineers from NASA and Pratt & Whitney Rocketdyne successfully completed a series of hot-fire altitude tests using liquid methane on the RS-18 engine. The tests, conducted at White Sands test facility in New Mexico, are part of the technology development for NASA's Constellation program, and gathered important data on ignition, performance measurement, and rapid start and stop.

The SSP program in conjunction with Cx and ISS have been asked by the administrator to put together some manifest options to assess extending shuttle flights to 2015. SSP would like to have some options developed for review by senior management by the end of September. The result of the review might be a formal budget assessment of a option(s).

Tanned, dirty and hungry, two men who spent three months crossing the Pacific on a raft made of plastic bottles to raise awareness of ocean debris finally stepped onto dry land.

"We made it," hollered Marcus Eriksen to a crowd of about two dozen gathered at Ala Wai Harbor on Wednesday. "Where's the food?"

Friends greeted Eriksen and fellow eco-mariner Joel Paschal with lei, fresh food and beer to celebrate the end of their 2,600-mile voyage on what they call the JUNK raft.

When the builders of the Maple Ridge Wind farm spent $320 million to put nearly 200 wind turbines in upstate New York, the idea was to get paid for producing electricity. But at times, regional electric lines have been so congested that Maple Ridge has been forced to shut down even with a brisk wind blowing.

That is a symptom of a broad national problem. Expansive dreams about renewable energy, like Al Gore’s hope of replacing all fossil fuels in a decade, are bumping up against the reality of a power grid that cannot handle the new demands.

The dirty secret of clean energy is that while generating it is getting easier, moving it to market is not.

The New York attorney general, Andrew M. Cuomo, announced an agreement on Wednesday with one of the country’s largest builders of coal-fired power plants that would require the company to disclose to investors the financial risks of global warming.

When the Federal Bureau of Investigation announced it had cracked the long-unsolved anthrax case, the turning point cited by the bureau was its identification of a laboratory flask as the source of the anthrax.

The dots, or in this case more than a thousand separate anthrax samples, were connected with the help of a group of scientists working secretly for some seven years. They succeeded by using a combination of new techniques not even invented in late 2001 when the anthrax-laced letters were sent, and that most old-fashioned attribute of expert scientists and detectives: a trained eye.

A reaction to McCain's recently announced technology policy. (Stupidly unclear in the video: the initial graph is U.S.'s global ranking in broadband penetration -- so starting high (#5) in 2000, and declining to #22 by 2008. The rankings are based on OECD data.)

"When I was growing up, NASA united Americans to a common purpose and inspired the world with accomplishments we are still proud of. Today, NASA is an organization that impacts many facets of American life. I believe NASA needs an inspirational vision for the 21st Century. My vision will build on the great goals set forth in recent years, to maintain a robust program of human space exploration and ensure the fulfillment of NASA's mission. Together, we can ensure that NASA again reflects all that is best about our country and continue our nation's preeminence in space."
