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 that can be supplied to the power grid.
⁘It⁘s not really that different from solar PV,⁘ Dr. Leet Wood, chief energy advisor for the Space Frontier Foundation , explained as a guest on The POWER Podcast . ⁘There are a number of different architectures that have been considered over the years, and I should point out that this concept has been around for a number of decades, but the one that we⁘re most focused on is a large-scale satellite with a large solar PV array in geosynchronous orbit.⁘
⁘The behavior of space-based solar power is unique as an energy resource,⁘ Alex Gilbert, a fellow at the Payne Institute for Public Policy, said on the podcast. ⁘It does resemble renewable energy in that it has relatively limited environmental impacts⁘you do have to consider the small emissions from rocket launches⁘but from a greenhouse gas perspective, it is likely to be a net carbon reducer.⁘
