Scientists anticipate building kilometres-wide arrays of solar panels that would orbit Earth at a distance of around 36,000 kilometres. The energy that they harvest would be converted to microwaves and beamed down to surface-based receivers with even larger physical footprints.
Solar panels could produce more energy if reflectors were placed in orbit around the Earth to direct sunlight towards solar farms at dawn and dusk, researchers have said. The University of Glasgow team said the plan could help accelerate the transition to net zero and significantly boost the output of future large-scale solar farms.
It sounds too good to be true: a plan to harvest solar energy from space and beam it down to Earth using microwaves. But it's something that could be happening as soon as 2035, according to Martin Soltau, the co-chairman at Space Energy Initiative (SEI) - a collaboration of industry and academics.
Here on Earth, sunlight is diffused by the atmosphere, but in space it comes directly from the sun without interference. So a space-based solar panel can collect a lot more energy than a similar sized one on Earth. Similar projects are under development elsewhere.
Unlike intermittent renewable-energy sources on the ground, these orbiting panels would always bask in bright sunlight and would potentially offer a continuous supply of power. Now such schemes are beginning to look possible, thanks to cheaper hardware and the falling cost of space launches.
The rest is returned to the environment as heat. The panels are usually much darker than the ground they cover, so a vast expanse of solar cells will absorb a lot of additional energy and emit it as heat, affecting the climate. If these effects were only local, they might not matter in a sparsely populated and barren desert.
