Metamaterial Breaks Thermal Symmetry, Enables One-Way Heat Emission
Scientists have created a groundbreaking metamaterial that breaks Kirchhoff’s law by emitting 43% more mid-infrared radiation in one direction than it absorbs. Built from layered InGaAs and tested at 512°F with a 5T magnetic field, the structure exhibits record thermal nonreciprocity. This breakthrough enables controlled one-way heat flow, a ste...

US Air Force Plans to Harvest Solar Energy in Space, Send It to Earth
US Air Force (USAF) is trying to make space-based solar power a reality. The USAF aims to achieve something that it believes will go a long way in addressing the energy demand of its military personnel deployed at remote bases in the short term. However, it would ultimately be made available for civilian use.
