In this case, no real bacteria were used, but Shendruk said that\u00a0<i>E. coli <\/i>bacteria<i>\u00a0<\/i>have been commonly used in experimental works.<\/p>\n<p>Shendruk explained that when many bacteria swim together, they swarm and drive chaotically swirling flows that scientists call \u201cactive turbulence.\u201d Harnessing these impromptu flows to do anything useful is tricky, because they\u2019re so disorderly. For example, when Shendruk and his team pinned a single freely rotating disc in a simulation of active turbulence, results were not good: \u201cIt was spun randomly around, like a weather vane in a hurricane.\u201d<\/p>\n<p>The key finding was placing\u00a0an entire array of rotors in active turbulence. Thanks to the array, spinning spontaneously organizes. \u201cWhen I saw the array of rotors each rotating in the opposing direction of its neighbors, I thought <em>What on earth? Oh, that\u2019s cool,\u201d<\/em>\u00a0Shendruk remembered.<\/p>\n<p>The team discovered that as long as the rotors were close enough together, every single rotor in the simulation permanently obeyed the pattern. However, the system produced the tiniest imaginable amount of power.<\/p>\n<p>\u201cCharging an entire cell phone is inconceivable to me right now,\u201d said Shendruk. \u201cTo give an idea of just how small the amount of work we\u2019re talking about is,\u00a0let me say that a previous work on a microscopic gear in a bacteria swarm was estimated to give 1 femtowatt.\u201d<\/p>\n<p>One femtowatt is\u00a01.0\u22c510<sup>-15 <\/sup>watt.<\/p>\n<p>\u201cEven huge arrays of rotors won\u2019t power your entire cell phone. But it might provide a little power to a microfluidic device that is being used to produce cells or to power a tiny microbot,\u201d\u00a0Shendruk said. \u201cIt\u2019s very possible that someone could build this experimentally and that would be really neat.\u201d<\/p>\n<p>Source:\u00a0<a href=\"http:\/\/advances.sciencemag.org\/content\/2\/7\/e1501854.full\" target=\"_blank\" rel=\"noopener\">http:\/\/advances.sciencemag.org<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A team of scientists from Oxford University used a virtual prototype to demonstrate\u00a0how the natural movement of bacteria could be harnessed to turn cylindrical rotors and provide a steady power source.
