Description

Can space-based solar power actually give humanity free, unlimited energy by 2030?John Bucknell, former SpaceX Senior Propulsion Engineer on the Raptor rocket engine and CEO of Virtus Solis, reveals how orbital solar power could drop energy costs from $40 per megawatt hour to just 50 cents, solving the energy trilemma that no other technology can achieve.PERFECT FOR LISTENERS INTERESTED IN:- Space technology and commercial space industry- Clean energy solutions and climate tech innovation- SpaceX, Blue Origin, and the future of orbital infrastructure- AI data center power challenges- Gerard K. O'Neill's The High Frontier vision- Post-scarcity economics and energy abundanceWHAT YOU'LL DISCOVER:- Why Elon Musk reversed his position on lunar mining versus Mars colonization- How space-based solar power achieves clean, firm, and affordable energy—the only technology that does all three- The real economics: 3 to 5 cents per kilowatt hour initially, dropping to 0.05 cents after financing- What happens to capitalism when energy becomes essentially free- Why Kessler Syndrome concerns about orbital debris are misunderstood- The 2030 timeline for Virtus Solis.Please Enjoy the show.--Other ways to connect with us:⁠Listen to every podcast⁠Follow us on ⁠Instagram⁠Follow us on ⁠X⁠Follow Mark on ⁠LinkedIn⁠Follow Jeremy on ⁠LinkedIn⁠Read our ⁠Substack⁠Email: [email protected] JOHN BUCKNELL:John holds over 46 patents in propulsion and energy systems.
