Space-Based Solar: The $10 Megawatt Hour That Can Save Us | Martin Soltau

Oil above 100 USD. The Strait of Hormuz under pressure.The world scambling for energy. Again. and Again... Every energy crisis sends us looking for the same answers: another pipeline, another terminal, another sanctions package. But what if the real way out is not on Earth at all? Martin Soltau, Co-CEO of Space Solar, returns to the show with a roadmap that has hardened into something impossible to ignore. His UK startup, nine people and £10 million in funding, is building Cassiopeia: a modular solar power satellite designed to harvest energy in geosynchronous orbit and beam it down to receivers on Earth, 24/7, all weather, gigawatt scale. Independent analysts price it at around $10 per megawatt hour, roughly ten times cheaper than today's wholesale energy. A solar panel in orbit produces 13 times more energy than the same panel on the ground. In this conversation we get into the part most people miss. This is not a physics problem, it is engineering the economics, and the milestones are real. First in-orbit demonstration in two years. Minimum viable product by 2030. First commercial 600 MW satellite in geosynchronous orbit by 2033. Martin makes a sharp case for why wind and solar alone cannot scale fast enough, why the UK is now paying the highest energy prices in the developed world despite one of the world's most ambitious clean energy programmes, why orbital data centres are the wrong answer to AI's energy hunger, and why a technology that uses 1000 times less critical minerals than ground-based renewables could finally break the link between energy and geopolitics. If you care about energy security, decarbonisation, or where the next decade of clean power is actually coming from, this is the conversation worth your time.
