The American greening of Geneva: Switch Flipped for Magnetic Levitation Cooling

The Mission’s new air conditioning system gives the US an opportunity to showcase cutting edge technology, an air cooling chiller system that uses no lubrication oil and a minimal amount of refrigerant in comparison to typical chilling systems. It is a long-awaited commercial application of a solution to a decades-old engineering dilemma of how to maintain a magnetic levitation motor shaft within microscopic tolerances. Magnetic levitation dates back to the 1940s, but nanotechnology was required for this step.
