Setting Micro Gears In Motion

jim.b0b writes: "ScienceDaily has a nice article on lateral Casimir force and its possible impact on Micro Machines. 'One can envision a device fabricated with two corrugated surfaces allowing for a sliding motion between the two surfaces. The normal Casimir force would move the membrane up and down in the vertical plane, while the lateral Casimir force would slide it back and forth. Thus, on a silicon chip you can have vertical and sliding motions of a micro device.'"
