The technology for harvesting critical minerals from the ocean floor has barely changed since the 1960s. Big tracked vehicles.

Vacuum dredges. Sediment plumes.

The same architecture, decade after decade.

Oliver Gunasekara looked at that and saw an opportunity.

He's the CEO of Impossible Metals, a deep tech startup building a fleet of autonomous underwater robots designed to collect polymetallic nodules from the seafloor with a fraction of the environmental disruption of conventional methods.

On this episode of Disruptors for Good, Oliver walks through the technology, the regulatory landscape, the environmental tradeoffs, and why he thinks the first commercial deep sea mining operations are closer than most people realize.
