Summary:
Aetherflux is developing a new space-based solar power technology using infrared lasers.
The startup plans to launch a demonstration satellite by early 2026.
Their modular approach allows for iterative development of smaller satellites.
Initially targeting defense applications, particularly for forward operating bases.
Self-funded by Baiju Bhatt, with initial investments around ten million dollars.
Aetherflux's Innovative Vision
Aetherflux, a startup led by Baiju Bhatt, co-founder of Robinhood, is pioneering a new approach to space-based solar power (SBSP), aiming to create a more scalable and affordable solution. Announced on October 9, the company plans to deploy a constellation of satellites in low Earth orbit that will collect solar energy and transmit it back to Earth using infrared lasers.
Modular Design for Flexibility
This innovative concept marks a significant departure from traditional SBSP designs that rely on large arrays in geostationary orbit. Bhatt emphasizes that their modular approach allows for iterative development, making it feasible to build smaller, more manageable satellites that can be improved over time.
Upcoming Demonstration
The first mission is set to launch by early 2026, featuring a kilowatt-class spacecraft that will test the technology by transmitting power to the ground with a spot size of 10 meters. Future satellites are expected to generate even more power at a lower cost per kilowatt-hour.
Overcoming Challenges
While Aetherflux's approach presents certain technical challenges, such as the need for power storage and a constellation handoff system, it aims to target defense applications initially. Bhatt points out that forward operating bases could greatly benefit from this technology, especially in areas where fuel supply is difficult.
Historical Context
The concept of SBSP is not new; a 2007 study by the former National Security Space Office highlighted its potential but was largely overlooked. Aetherflux's demonstration mission is just the first step in a “crawl, walk, run” strategy to develop a viable SBSP capability.
Funding and Future Plans
Bhatt is self-funding Aetherflux, with initial investments in the ten-million-dollar range, enough to cover the first demo mission. The company currently has just under 10 employees.
Industry Perspectives
Despite a skeptical assessment from a recent NASA report regarding the cost-effectiveness of SBSP compared to terrestrial renewable energy, Bhatt believes his modular strategy offers a promising path forward. The SBSP community continues to explore new analyses and research to validate the feasibility of these systems, especially with advancements in launch technologies like SpaceX's Starship.
Conclusion
Aetherflux is setting the stage for a transformative shift in how we harness solar energy from space, with the potential to power applications around the world, starting from military operations to commercial viability.
