What are Space Solar Power Stations?

Solar power gathered far away in space, seen here being transmitted wirelessly down to Earth to wherever it is needed

Advantages of Space Solar Power Stations:

1. Unlimited Clean Energy: Space solar power stations can provide a virtually limitless source of clean energy without depleting Earth's resources.
2. All-Weather Energy: Unlike ground-based solar power plants, space solar power stations are unaffected by weather conditions or changes in daylight hours, ensuring a consistent energy supply.
3. Global Energy Distribution: By placing these stations around the equator, they can provide energy to any part of the world, even remote areas, contributing to global energy access and security.
4. Reduced Environmental Impact: Space-based solar power is environmentally friendly, with no air or water pollution, and minimal land usage compared to conventional power plants.

      
     
Space Solar Power and Wireless Transmission

The physics involved means that these satellites would have to be large, on the order of several kilometres in size, to generate the equivalent power of a typical nuclear power station. The same would be true for the collecting ‘rectennas’ down on Earth’s surface.

The infrastructure on the ground will be allegedly less obtrusive than that of other renewables
Photovoltaic plants on the ground devour huge areas of land to harvest any reasonable amount of power. Wind farms in the landscape, too, are unmissable. The rectifying antennas (or rectennas) needed to receive microwave beams carrying solar power generated in space would too require a huge footprint. These rectennas will, however be far less obtrusive, claimed Cash, and allow for other uses of the land or sea on which they will be built.

It could power flying airplanes
In Airbus' idea of the future, solar power produced in space could contribute to cleaning up the hard-to-deal-with carbon footprint of aviation. Not that it would wean aircraft off fossil fuels entirely, but it could make a little dent in the amount of greenhouse gas the world's aircraft discharge into Earth's atmosphere.

The technology is less science fiction than you might think
Ian Cash is a British engineer, whose CASSIOPeiA Solar Power Satellite concept has been adopted by a U.K. government-backed space energy initiative as a starting point for a potential future space-based solar power plant demonstrator. A staunch advocate of the technology, Cash thinks that developing and building a solar farm in space presents fewer challenges than cracking nuclear fusion.

It provides perfectly clean electricity 24/7
Space-based solar power doesn't suffer from the main drawback plaguing most main renewable energy generation technologies. In space, the sun always shines. No clouds ever block the sun's rays from reaching photovoltaic arrays. And if you choose the orbit wisely, you can even avoid the night. A solar power plant in space, unlike its equivalent on Earth, or an off-shore wind farm, would provide a constant amount of power 24/7 year-round. This power would feed Earth-based power grids at a steady rate without having operators worry about pesky blackouts or sudden overloads.
