We have seen systems wirelessly transmit data through different means but never have we seen modulated sunlight being used to send data. Some scientists at the King Abdullah University of Science and Technology, a private research institution located in Saudi Arabia, made some special polarized smart windows that can modulate the sunlight passing through it, […]
