Episode Details

In this episode we speak with Lauren Flanagan, CEO of Sesame Solar, which builds mobile nanogrids. The product is a self-contained unit that generates its own power from solar, batteries, and stored hydrogen, set up by one person in fifteen minutes. The company started in emergency response and extreme weather, and has moved increasingly into defense. The newer focus, and the one we spent most of the episode on, is using these nanogrids to refuel hydrogen drones in the field.

Most of the conversation was about whether that case holds up. Lauren's argument is that contested logistics have changed the math: fuel at the edge can run a thousand dollars a gallon all-in, the resupply convoy is a target, and the real cost is the lives spent guarding it, so making power where you stand becomes a strategic question rather than an efficiency one. We pushed on the parts that are harder to defend, the energy losses on the hydrogen path versus batteries, how thick the market for long-endurance hydrogen-powered flight actually is, and how you get from a fifty-day reserve to a six-month operational promise that's still backed by simulation rather than field data. Lauren was candid about what's proven and what isn't, and about which problems are physics and which are just adoption friction.
