Space has never had a power grid. Until now. The Star Catcher Network beams concentrated solar energy directly to satellites in orbit. Up to 10x more power, on demand, with no retrofit. This is the infrastructure that unlocks the next era of space.

This is redundant if the customer satellites are designed correctly, no? You are receiving the same sunlight with the same solar panels as them, so this design doesn’t decrease total launch mass to achieve a certain goal, therefore adds no value.

Hahaha... 70% energy loss on initial capture of the energy and another 70% loss at the satellite. This means the system is 9 percent efficient overall. Sorry, back to the drawing board.

Until now, you say? Amazing. Great use of the present tense, there. So where is it currently beaming this wondrous concentrated power to? Or is it in fact limited to a Powerpoint deck at present, until such time as SpaceX decides if it is worth doing, and then does it.

This could save a lot on solar panel mass for satellites.

This could transform CubeSat capabilities! More power without hardware changes is exactly what small satellites need!

Huh… could have sworn Peter Glaser and John Mankins both while under Arthur Kantrowitz did exactly that oh some 60ish years ago. Maxwell hunter was involved from 67 on as well. Even Wallace Manheimer.

Star Catcher Industries’ space-based optical power beaming technology raises several legitimate concerns that challenge its feasibility, scalability, and broader implications. These aren’t dismissible as minor hurdles; they represent fundamental barriers that could undermine the system’s practicality or lead to unintended consequences. Fundamental Physics and Efficiency Mismatch: Achieving a claimed 10x power boost to a satellite’s photovoltaic (PV) output requires massive solar collectors on the power nodes, potentially 50–100x larger than the client’s receiver area, once accounting for end-to-end conversion losses (e.g., sunlight to electricity to laser to reconversion at ~10–20% efficiency). This inefficiency chain poses a serious problem: it could render the system energetically wasteful and economically uncompetitive compared to simply deploying larger onboard solar arrays, demanding breakthroughs in laser efficiency, beam concentration, and loss minimization to avoid being dismissed as overhyped “techno-woo.” Collector Size and Mass Overhead: The need for enormous, lightweight concentrators (e.g., Fresnel lenses or mirrors) on shared orbital nodes introduces a critical scaling issue: launching and assembling these structures in space would incur prohibitive mass penalties, high costs, and complex thermal management requirements. This problem exacerbates launch economics and orbital debris risks, requiring innovative materials, in-space manufacturing, or cost-sharing models across multiple clients to prevent the infrastructure from becoming an impractical burden that outweighs any power delivery benefits. Accelerated PV Degradation from Intensified Light Exposure: Delivering concentrated light (up to 10 Suns equivalent) to off-the-shelf solar panels risks shortening their operational lifespan, as cumulative photon flux could accelerate thermal stress, coverglass degradation, or other wear mechanisms beyond standard radiation damage models. Even if not directly proportional to intensity in all cases, this remains a serious durability problem: it could lead to premature burnout of client satellites’ arrays, necessitating advanced cooling systems, hardened PV materials, or intermittent beaming protocols to ensure mission longevity without requiring extensive retrofits. Radiation Pressure and Station-Keeping Disruptions: The momentum transfer from high-intensity laser beams exerts a tangible force (e.g., millinewtons for kW-scale incidents), pushing receiving satellites off-course and increasing the demand for reaction mass or propellant in attitude control systems. While small in isolation, this cumulative thrust over repeated beaming sessions presents a serious orbital stability problem: it could inflate fuel budgets, complicate precise positioning for constellations, and amplify existing perturbations like solar radiation pressure, requiring enhanced thruster efficiency or beam modulation techniques to mitigate without eroding the net power advantage. Dual-Use Weaponization and Treaty Compliance Risks: A successful, high-power orbital beaming network inherently enables easy repurposing for anti-satellite applications (e.g., dazzling sensors or damaging assets with sustained kW–MW beams), raising profound geopolitical concerns about violating the spirit of treaties like the 1967 Outer Space Treaty or emerging norms against space weapons. This dual-use dilemma is a serious regulatory and ethical problem: it could provoke international arms races, export controls, or outright bans, demanding verifiable safeguards, transparency measures, and diplomatic frameworks to separate civilian energy delivery from military exploitation while avoiding escalation in an increasingly contested space domain.

Oh cool you guys hiring?

This would reshape satellite ops by cutting panel mass and enabling bigger missions on demand

Looks redundant. Just build it into satelites - less cost

very nice, i was thinking closer to the sun but that works

@grok in our lifetime

I mean looks like a laser weapon 🤣

We need SSO for power and LEO for the comms and datacenters.

Cool

will the beams be visible from earth eyes/telescope ?
