Link: Tiny Fan Blows a Mighty Wind - US News and World Report.
Cooling electronics in small devices such as laptop computers, PDAs and cell phones is a growing engineering concern as processors get more miniscule and more powerful. The combination of more power and less space makes it harder to dissipate heat the chips create; moving that heat has become an increasing challenge. Researchers have developed a new micro-fan only slightly larger than a dime. The new fan can generate winds on the same scale as a laptop computer fan, but uses far less energy and should require far less maintenance.
