The Best Asteroid Mining Method? Closed-Loop Electrochemistry (SEM TECH Explained)

Asteroid mining always hits the same wall: chemicals are heavy, expensive to launch, and impossible to resupply at scale. Most proposed extraction methods quietly assume a constant flow of consumables from Earth. In this video, I explain why SEM TECH (Salt Electro Mining Technology) is the most practical asteroid-mining approach, because it’s closed-loop. Instead of launching barrels of acids and oxidizers, SEM TECH is designed to generate and regenerate its chemistry on-site using electrolysis + a salt-based feedstock, with relatively low power. I also break down a major 2025 paper on carbonaceous asteroids (MNRAS) and show why SEM TECH directly addresses the exact problems the study highlights—especially heterogeneous composition, geological “messiness,” and difficult-to-separate mineral forms—because electrochemistry is built for conversion + separation, and SEM TECH accepts a wide range of feedstocks. In this video: Why chemical resupply is the #1 killer of asteroid mining How closed-loop electrochemistry changes the economics Why asteroid heterogeneity doesn’t matter when your process is feedstock-flexible How electrochemistry solves “native metal conversion” + tough separations Carbon-rich asteroids: fuel + manufacturing feedstock potential The only two real blockers SEM TECH doesn’t solve: low-gravity robotics + legal frameworks The twist: Do I think we need asteroid mining? No. A 2025 study from Colorado School of Mines suggests existing mining waste can contain enough critical minerals to supply industry needs. Meaning we may not need space mining… and we may not even need to dig new holes at all. Cleaning up existing waste is more than enough and SEM TECH is built for that.
