Sandia National Lab team 3D prints 20% more efficient solar power receivers

A team from Sandia National Laboratories, one of three National Nuclear Security Administration research and development laboratories, says it has developed fractal-like concentrating solar power receivers that are more effective at absorbing sunlight that existing systems. The breakthrough, which was enabled by 3D printing technology, is being investigated by both the U.S. and Indian governments as a potential way to increase the effectiveness of solar power energy.
