Hasta La Gadget!

It’s funny, really. We’ve figured out how to put men an women on the moon and repair an orbiting telescope, but we can’t concoct an AA battery that lasts more than four days inside a Teddy Ruxpin. Thanks to a revolutionary new design from the labs at the University of St Andrews, all that could be well on the way to changin’. Researchers at said institution have teamed up with partners at Strathclyde and Newcastle in order to design an air-fuelled STAIR (St Andrews Air) cell that could theoretically last up to ten times longer than current batteries. Put as simply as possible, this design utilizes oxygen in the air as a re-agent instead of heavy, costly chemicals; the result is a lighter, cheaper battery with loads more capacity. Needless to say, gurus within the project are already dreaming of a prototype to fit in small gizmos such as cellphones or MP3 players, though we wouldn’t expect one anytime soon — after all, there’s still two years of research left to complete.

The Wall Street Journal has reported that the electricity grid in the United States has been infiltrated by “cyperspies,” in an attempt to map the infrastructure, leaving behind software that could pose potential threats in times of crisis. Quoting anonymous “current and former” national security officials, the report claims that the spies, hailing from China, Russia, and “other countries” have not attempted to do any damage, but that they could, and that these types of intrusions are on the rise. Officials are of course worried about the potential implications of such penetrations, noting that much of our infrastructure, including nuclear power plants and financial institutions, are at risk. Unfortunately for the WSJ and its Cold War-era headline, the article goes on to state that it’s not really possible to know whether a particular attack is “government sponsored,” or just the work of regular old hackers from those regions running amok in cyberspace. Additionally, spokespeople from the Russian and Chinese Embassies vehemently deny their respective governments involvement in any such work. The Wall Street Journal, of course, fails to point out the most obvious of explanations: it’s aliens.

Update: China has officially responded to the report. From a WSJ blog post:

“The intrusion doesn’t exist at all,” Chinese Foreign Ministry spokeswoman Jiang Yu said at a regular press conference. “We hope that the concerned media will prudently deal with some groundless remarks, especially those concerning accusations against China.”

“I have also noticed that the U.S. White House had denied the media reports,” she said.

The New York Times is reporting Google will announce a free web service tomorrow called PowerMeter that’ll let users track energy consumption in their homes or business, provided there’s a means to upload the data. That part of the equation’s gonna be up to other companies to create compatible devices, and while no manufacturing partners have been named, we’d suspect strange bedfellow GE will probably jump aboard pretty quickly. The service is expected to roll out in the next few months. Ready to give the boys in Mountain View even more access to your life?

Update: The official site has launched. According to the FAQ, PowerMeter is currently in closed beta. There’s also a video about the program, which you can peep after the break.

University of Illinois researchers have developed what they claim is the world’s smallest working fuel cell, and it’s certainly a good bit tinier than anything we’ve seen. The itty-bitty battery measures 3 mm x 3 mm x 1 mm and is comprised of just four layers: a water reservoir, a thin membrane, a chamber of metal hydride, and an assembly of electrodes. It can produce 0.7 volts and a 0.1 milliamp current for about 30 hours, with a newer model boasting similar voltage and 1 milliamp of current. That’s not gonna juice your BlackBerry anytime soon, but scientists suggest it could be used for simple electronics and microbots. As for future application, we’re hoping one day can power a fingernail-sized smartphone.

Not that waste heat in general hasn’t been repurposed for non-wasteful activities before, but researchers at Doshisha University are now edging ever closer to making useful the previously annoying thermoacoustic phenomenon. For those not really tied into the science realm, said phenomenon is a nonlinear one in which “heated air autonomously transforms into sound when passing through small mesh holes in a wire sheet.” Gurus are now developing a cooling technology that would have heat converted to sound, where it would then be transferred through a tube and reconverted into heat; furthermore, other whiz-kids are looking to generate actual electricity from the racket. In related news, the thermoelectric conversion is being used to transform waste heat from candles into energy for LEDs, which would emit more light than the candle powering it. Pop on past the break for a demonstration of the former.
