By Eugenie Samuel Reich A NEW technique that exploits the Casimir effect – a strange quantum phenomenon that gums up nanoelectromechanical systems – may pave the way for a switch that could cut the power consumption of nanoscale gadgets. The Casimir effect is a force that tries to push together conducting plates held within a few micrometres of each other. It arises because of the quantum electromagnetic fluctuations that occur in a vacuum. The proximity of the two plates constrains the fluctuations in the gap between them. This makes them weaker than fluctuations in the surrounding space,
