Space-Based Solar Power Economics.
🔋 SpaceX’s modified Starlink satellites could achieve $10 per watt for space-based solar power by 2030–2032, dramatically cheaper than the $100 per watt estimate for version 3 satellites and competitive with ground alternatives.
☀️ Space-based solar energy delivers 10x more effective capacity than ground-based sources due to 24/7 operation, double intensity from unfiltered sunlight, and 5x faster production speed, making 100–200 GW/year by 2030 equivalent to hundreds of nuclear plants.
💰 Starlink’s V3 solar panels currently cost $1.2 million for 68 kilowatts, facing challenges in radiation hardening, thermal cycling, and radiative cooling compared to typical $200-500k/watt costs on Earth.
Launch Infrastructure and Scaling.
🚀 Launching 1 gigawatt of solar power requires 25 Starship launches, meaning the target of 100–500 gigawatts per year demands 2,500–12,500 launches annually, constrained by natural gas consumption and physical launch site limitations.
📈 SpaceX’s existing 200 MW Starlink constellation and planned 2 GW production by 2028 can be rapidly scaled to 100 GW/year by 2030–2033 through exponential manufacturing expansion.
🏭 Achieving 100–200 GW/year by 2030 requires 10-30x more launches and 10-20x more solar factories in orbit, with Starship’s scaling being the only viable path to this production level.
AI Compute and Energy Demand.
💻 Space-based solar power will become the lowest cost AI compute within 4–5 years due to continuous solar availability eliminating battery costs, even before exhausting Earth’s energy sources.
⚡ Scaling to 1–2 TW/year of AI compute in space is impossible on Earth due to requiring terawatt-scale power plants, while space offers continuous solar energy without battery infrastructure.
🌍 Space-based solar power becomes the only viable option for 1–2 TW/year of energy, as ground-based alternatives max out at 10–20 GW/year and cannot scale to match space capabilities.
Chip Production Bottlenecks.
🔬 Nvidia and TSMC cannot meet 200 GW/year AI chip demand by 2030, as TSMC projects only 50M GPUs/year supporting 100 GW of power, while 200 GW requires 100-200M chips/year.
🎯 AI chip production is the limiting factor for scaling to 200 GW/year by 2030, as 50M chips/year supports only 50 GW, creating a critical supply chain constraint.
Thermal Management Challenges.
🌡️ 95% of a 4 km² space solar farm’s mass is dedicated to capturing solar energy and radiating heat away from AI chips, representing a first principles thermal management problem for all space-based compute.
Economic Impact Projections.
