Space power: The dream of beaming solar energy from orbit
A What happened
The idea of harvesting solar energy in space and transmitting it to Earth has gained traction, with several companies conducting tests to demonstrate its feasibility. A recent experiment at a Florida stadium showcased the ability to beam concentrated sunlight over a distance, marking a significant step toward realizing space-based solar power. This technology promises to provide clean energy without the atmospheric limitations faced by terrestrial solar panels. Countries like the US, UK, Japan, and China are investing in this technology, which could potentially meet a large portion of renewable energy needs. However, challenges remain, including the need for massive satellite constellations and concerns about costs and space debris management. Despite these hurdles, advancements in technology and decreasing launch costs are making space-based solar power a more realistic prospect.
