BSV Podcast 0141: Volta Space

Balerion Principal Emerson Garnett sits down with Justin Zipkin, Co-Founder & CEO of Volta Space, to discuss lunar power infrastructure. Volta Space is developing LightGrid, a satellite-based system designed to beam power from lunar orbit to assets on the surface. The company is addressing the 14-day lunar night problem by enabling landers, rovers, and sensors to operate through darkness and in permanently shadowed regions.Timestamped Overview00:00 – Introduction to Volta Space and the lunar energy grid00:50 – Origin story, customer discovery, and NASA’s Watts on the Moon challenge02:16 – Lunar night, temperature extremes, and why missions struggle beyond 14 days03:38 – Powering permanently shadowed regions and increasing rover operating time05:10 – Artemis infrastructure priorities, CLPS cadence, and the unresolved power gap09:57 – LightGrid architecture, laser power beaming, and photovoltaic receivers13:52 – Orbital energy collection, laser transmission, and constellation scalability16:09 – Targeting safety, receiver design, and surface mass tradeoffs21:00 – Terrestrial field demonstrations and lessons from 850-meter power beaming tests23:05 – Blue Ghost 2 light port test and DCubed 400-watt laser demonstration25:01 – Roadmap to operational lunar power delivery and reliability milestones26:54 – Civil, defense, and international interest in lunar power infrastructure29:41 – Canadian Space Agency architecture study and lunar power-system trade space31:29 – Earth applications, power over fiber, and Arctic drone operations35:56 – Pricing, reservations, customer planning, and lunar utility economics40:18 – Lunar permanence, second-order economic effects, and coexistence with fission and solar47:58 – Customer and investor engagement and closing perspective This is a public episode.
