Space panels could soon beam electricity back to Earth

The video discusses the Photovoltaic Radio Frequency Antenna Module (PRAM), a solar panel technology tested on a space plane. PRAM, currently the size of a pizza box, can capture solar energy more effectively than terrestrial setups by absorbing blue light energy from sunlight. Although it currently transmits only 10 watts of energy, the technology has the potential to be scaled up to deliver significant amounts of clean energy to Earth, possibly enough to power entire cities. This could provide electricity to remote areas and during emergencies.
