Ah science, where would we be without it? Well it turns out that in a few years time we could all be using iPods and mobile phones that don’t even require batteries or mains power for their source of power. Instead they could rely on the movements of our own bodies to generate electricity – whether it be our heart beating, our legs moving or the pinch of our fingers!

A team of scientists presented their findings at a National Meeting & Exposition of the American Chemical Society, in which they used zinc oxide nanowires to generate electricity when strained and flexed.  Dr. Zhong Lin Wang of the team said of their findings:

This development represents a milestone toward producing portable electronics that can be powered by body movements without the use of batteries or electrical outlets.

Our nanogenerators are poised to change lives in the future. Their potential is only limited by one’s imagination.

Their latest development of the concept was thousands of times more powerful than their previous attempts and Dr. Wang is hopeful that if they can sustain the rate of improvement the nanogenerator could be used for a “broad range of other applications that require more power.” Five nanogenaroters can currently produce a cumulative total of about 1 microampere at 3 volts, which is equivalent to 2 AA batteries – a substantial increase from previous versions.

If you recall, last week we reported on a request from four US Senators that Apple remove apps that warn and alert users of where DUI (driving under the influence) checkpoints are. Well the Association for Competitive Technology, a group of thousands of independent software developers has responded to this request by the Senators and objected to the reasoning of the claims.

Rebutting the contention that the apps are “harmful to public safety”, the group’s president, Jonathan Zuck, said that the concerns raised are actually “in conflict with the public interest on the issue of traffic safety.” Citing the National Highway Safety Administration, he goes on to say that heightened awareness of DUI checkpoints acts as a deterrent to illegal behaviour and that “several of the apps in question have received particular commendation from the law enforcement community.”

Furthermore some of the apps in question, including PhantomALERT (which is part of the A.C.T. group) and Trapster use data from the public domain - some of which is required by law to be published, this data will continue to live on regardless of whether some smartphone apps are pulled. Meanwhile, RIM last week removed PhantomALERT from it’s app store and was applauded by the Senators who issued a statement saying “Drunk drivers will soon have one less tool to evade law enforcement and endanger our friends and families. We appreciate RIM’s immediate reply and urge the other smartphone makers to quickly follow suit.” Jump the break for the A.C.T. group’s full response to the Senator’s request.
