Student Invention May Significantly Extend Mobile Device Battery Life 160

imamac writes with this excerpt from news out of Carleton University: "Atif Shamim, an electronics PhD student at Carleton University, has built a prototype that extends the battery life of portable gadgets such as the iPhone and BlackBerry, by getting rid of all the wires used to connect the electronic circuits with the antenna. ... The invention involves a packaging technique to connect the antenna with the circuits via a wireless connection between a micro-antenna embedded within the circuits on the chip. 'This has not been tried before — that the circuits are connected to the antenna wirelessly. They've been connected through wires and a bunch of other components. That's where the power gets lost,' Mr. Shamim said." The story's headline claims the breakthrough can extend battery life by up to 12 times, but that seems to be a misinterpretation of Shamim's claim that his method reduces the power required to operate the antenna by a factor of about 12; 3.3 mW down from 38 mW. The research paper (PDF) is available at the Microwave Journal. imamac adds, "Unlike many of the breakthroughs we read about here and elsewhere, this seems like it has a very high probability of market acceptance and actual implementation."

CO2 To Fuel, Closing the "Carbon Loop" 316

leprasmurf writes "Inhabitat has posted an article detailing a recent announcement of a process to turn CO2 into fuel. The process, which used to be considered too energy inefficient, uses a multi-step, low pressure, and low temperature biocatalyst to break the CO2 into 'basic hydrocarbon building blocks.'"

Next-Gen Mars Rover In Danger of Cancellation 210

OriginalArlen writes "NASA's next-generation rover, the nuclear-powered, laser-equipped Mars Science Laboratory is reported to be at a serious risk of cancellation due to budget and schedule overruns, including non-delivery of vital parts by a subcontractor. Costs are running over $2B so far, and the already thin schedule of Mars missions planned for the next decade — with budget ring-fenced for an outer-planets flagship mission — is in danger of further cuts."
