AUSTRALIAN UNIVERSITIES TO LEVERAGE CROWD POWER FOR NEW WATER FILTERS
澳大利亚的大学群力探索新的水过滤器
By Editor on 9 September 2010
IBM’s World Community Grid has announced the Computing for Clean Water project, involving the University of Sydney, Monash University and China’s Tsinghua University.IBM的World Community Grid计划宣布（新的）子项目清水项目，悉尼大学、蒙纳士大学以及中国的清华大学。The Computing for Clean Water project will develop ways to filter and scrub polluted water, as well as convert saltwater into drinkable freshwater at a lower costs, complexity and energy expenditure than current techniques.清水计划的计算将改进过滤及净化污水的方法和咸水转淡的方法。后者与现有的技术相比能够降低盐水转化可饮用水的成本、复杂度以及能量消耗。The effort will seek to reduce the pressure and energy required to force water through microscopic, nanometer-sized pores in tubes made of carbon, whose tiny holes prevent harmful organic material from being transmitted.此次尝试将试图降低迫使水进入极小的碳纳米管中所需要的压强与能量。这些碳纳米管上的小孔可以阻止有害物质被传播开。To do so, scientists need to produce millions of computer simulations modelling how water molecules interact with one another and against the walls of the carbon nanotubes. 为了实现这一目标，科学家们需要制造上百万台计算机来通过模型模拟水分子之间如何相互作用以及它们如何与碳纳米管管壁作用。To accelerate this task, the scientists will harness the World community Grid to perform online simulations, crunch numbers, and pose hypothetical scenarios. The processing power is provided by a grid of 1.5 million PCs from 600,000 volunteers around the world. These PCs perform computations for scientists when the machines would otherwise be underutilized.
为了加速这一计划的进程，科学家们打算充分利用World Community Grid来进行在线模拟，数据处理以及提出可能的方案。这一进程的动力将由一个由60万人所提供的150万台电脑网络组成。这些计算机将在未被充分利用时为科学家们进行计算。
