Imagine a field of solar panels floating silently in the endless day of Earth’s orbit. Unlike their terrestrial cousins, this space-based solar array never faces nighttime, clouds, or atmospheric interference. Instead, they bathe in constant, intense sunlight, converting this endless stream of energy into electricity with remarkable efficiency.
But the true innovation lies in how this power is transmitted to power grids on Earth. The electricity generated in space is converted into invisible beams of microwaves or laser light that pierce through the atmosphere with minimal losses. These beams are precisely aimed at receiving stations on Earth—collections of antennas or receivers known as “rectennas” that capture and reconvert the energy back into electricity…
