Green technology is on the rise, but the U.S. still consumes an enormous amount of fossil fuels

The U.S. consumed 94.6 quadrillion BTUs of energy in 2009, more than any other nation. It also produced more energy than any nation but China: some 73 quadrillion BTUs.Those 94.6 quads break down into 308 million BTUs per capita--the equivalent of about 50 barrels of oil for every American.
The University of New Mexico discovered a treasure trove of old cutaway schematics of nuclear reactors, dating back as much as 50 years, in the pages of Nuclear Engineering International. If you're interested in nuclear power (or how stuff works) and are looking for some art to hang on your walls, we've got you covered.
A large Cold War supply of helium-3 has begun to rapidly run out, due to heavy demand from U.S. scientists who need the gas for neutron detectors and cryogenic experiments. Almost 60,000 liters of helium-3 were used in 2007 and 2008, compared to just 10,000 liters used annually about 10 years ago. A House subcommittee has been convened to search for a solution this week, New Scientist reports.
Nuclear power has long provided steady energy sources for everything from homes to deep space probes. Now researchers have begun developing a tiny nuclear battery the size of a penny that could provide power in a smaller, lighter, and more efficient package.
A newly formed International Committee on Robot Arms Control (ICRAC) has asked nations to ban military bots from space and prevent robots from toting nuclear weapons. No doubt, human characters from science fiction stories such as "Battlestar Galactica" and "Terminator" might agree.
To scope out a suspected Mafia shipwreck that may hold nuclear material, Italian authorities sent in the robot.
A remote-controlled sub began filming a sunken vessel off Italy's southern coast over the weekend. That shipwreck may represent just one of 30 ships deliberately sunk in a rather sociopathic act of nuclear waste dumping.
It's one of those ideas that just sounds wrong: a barge-like floating nuclear plant in the middle of the ocean. But despite its somewhat unconventional approach, a Russian firm we first reported on in 2006 is forging ahead with plans to have the first model ready to begin service in 2012.
As the Summer nears, reports surface of multiple security sweeps for radioactive material at Olympic sites

According to the Canadian Press, Chinese and American officials are working in cahoots to remove radioactive material from Olympic sites in advance of the games this summer in Beijing. The work is the latest hurdle the Chinese must overcome with the world watching closely. From pollution to human rights, press coverage to date has been less about the sport and more about the host.
American experts from the National Nuclear Security Administration (NNSA) have taken at least two trips to China hoping to eliminate any material that could be used as a dirty bomb.
We're getting better at detecting it, but the number of cases keeps growing.

Here's a mildly reassuring fact from today's AAAS news briefing on nuclear forensics: There are no known cases of a finished nuclear weapon being stolen or sold on the black market. But raw nuclear materials are a different story. In the past fifteen years, more than 1,300 cases of nuclear trafficking have been registered. Anita Nilsson of the International Atomic Energy Agency, a member of today's panel, said that most of these cases were "innocent," but some are anything but. The 400 grams of weapons-ready plutonium seized at the Munich airport in 1994?
