Thinking On Paper Space-based solar power: the energy trilemma, 50 cents per megawatt hour, and what happens to capitalism when energy is free
John Bucknell was senior propulsion engineer on the Raptor engine at SpaceX. He holds 46 patents and has designed a nuclear thermal turbo rocket. He now wants to solve energy. Not help with it. Solve it.
Virtus Solis puts solar panels in orbit, beams power to the ground via radio waves that pass through clouds and weather without loss, and delivers electricity at $30 to $40 per megawatt hour while the plant is being financed. Once the asset is paid off: 50 cents per megawatt hour. The UK pays $350 today.
John's argument is that every other energy technology fails at least one point of the energy trilemma: clean, firm, and affordable. Space solar is the only one that achieves all three. First plant: 2030.
This episode covers:
- The energy trilemma and why no terrestrial technology solves all three simultaneously
- UK energy at $350 per megawatt hour, what offshore wind's structural problems actually cost, and what deindustrialisation looks like when energy stays expensive
- Post-capitalism: capitalism optimises constrained resources. What happens to that system when energy becomes essentially free
- How cheap energy lets any country synthesise its own hydrocarbons from electricity, water, and CO₂, breaking the petroleum chokehold
- Kessler syndrome reframed: it only applies if objects in orbit are dumb. SpaceX does 800 collision avoidance manoeuvres a day
- Molniya orbit: why Virtus Solis is targeting a near-empty Russian spy satellite orbit from the 1960s
- Why Elon reversed from Mars to cislunar mining and what that signals · 2030 launch target and what the first commercial power plant in orbit proves
