WEST LAFAYETTE, Ind. — Research engineers at Purdue University are developing tiny, quiet fans that wiggle back and forth to help cool future laptop computers and other portable electronic gear. The devices remove heat by waving a small blade in alternate directions, like the motion of a classic hand-held Chinese fan. They consume only about 1/150th as much electricity as conventional fans, and they have no gears or bearings, which produce friction and heat.
