A new super-smart window can tint itself or become completely opaque when needed. It can also act as a solar panel, collecting energy from the sun for use within the home or building.
The new Large-Area Fluidic Windows (LaWin) system contains magnetic iron nanoparticles which can control the opacity of the window, blocking light to varying degrees and absorbing heat as needed.
The technology offers great potential for energy-efficient heating and cooling, as well as harvesting solar energy that would otherwise be wasted.
See New Atlas for more information as well as a research paper on the technology.
