[QUOTE="The Feedster, post: 507699, member: 259515"] If you're fed up with high electricity bills or just worried about your carbon footprint, then how about a technology that raises the possibility of computers and other electronic devices doing their thing on [URL="http://www.nature.com/nnano/journal/vaop/ncurrent/abs/nnano.2008.84.html"]as little as 0.001 per cent of current power consumption levels[/URL]? [URL="http://www.ntt.co.jp/news/news08/0804/080411a.html"]Researchers at Japan's NTT[/URL] have used nanotechnology to create a semiconductor that can perform computations on just a tiny fraction of the power even the best current devices use. [B]Binary digits[/B] Using [URL="http://en.wikipedia.org/wiki/MEMS"]MEMS[/URL] (microelectromechanical system) nanotechnology, the team has managed to produce tiny oscillating plates that reliably signal the zeroes and ones needed in calculations. Similar oscillation-based work - albeit on a much larger scale - has been done before, notably in [URL="http://www.thocp.net/hardware/parametron.htm"]NTT and Hitachi's Parametron[/URL] technology 50 years ago, but the key lies in the power requirements of the new device. [B]Fractions of power[/B] Holding a single bit of data requires just 10 picowatts, which is as little as one ten-thousandth of the power existing devices use. The fact that any MEMS computer would be much slower, however, means that several would be needed to achieve the same number-crunching ability, raising that fraction to around one thousandth. Whether the MEMS machine will ever result in super-low power bills and mega-long battery life for gadgets remains to be seen, but we may just have seen the future.
