Electromagnetic pulses (EMPs)—high-energy-density and ultra-wideband beams of electromagnetic radiation—are generated from sources such as nuclear explosions, high-power electromagnetic pulse devices, ...

Transparent new solar technology offers novel ways to use electricity around your home and could automate new and existing window functions. But your windows are still just glass panes in a frame.

A reflection-based solar cell design inspired by periscopes achieves near-complete visible transparency and record light utilization efficiency, outperforming all previous transparent photovoltaic ...
