Researchers have developed a 3D-printed device that generates twisting light beams with orbital angular momentum (OAM), a form of rotational energy that can carry more data than regular beams.

The Genius of Bladeless Vortex Hydropower explores the potential of small hydropower systems with a smaller ecological footprint compared to traditional dams. Many existing hydropower systems in the U ...
