On October 9, 2023, Aetherflux, a startup founded by Baiju Bhatt, announced plans to revolutionize space-based solar power (SBSP) by deploying a constellation of small satellites in low Earth orbit. This innovative approach aims to collect solar energy and beam it back to Earth using infrared lasers, marking a significant departure from traditional large-scale SBSP concepts that have struggled to move beyond theoretical designs.
The first demonstration satellite is scheduled for launch by early 2026, with the goal of creating a 'kilowatt-class' spacecraft capable of transmitting power to Earth. Aetherflux's modular design allows for iterative development, potentially lowering costs and increasing efficiency in energy production.
Bhatt emphasized that the technology could initially target defense applications, particularly in challenging logistics environments. He noted the importance of developing a system that can provide energy even at night, which presents unique technical challenges. The company is self-funded and aims to demonstrate the viability of its concept through a gradual 'crawl, walk, run' approach.
This development could have far-reaching implications for global energy solutions, especially in remote areas. Aetherflux's approach could revitalize interest in SBSP, which has seen fluctuating interest over the decades, and may pave the way for more sustainable energy sources in the future.
