Key points
- Jason Gillham, CTO/COO and co-founder of Impossible Metals, shows the company’s first buoyancy engine prototype, built from a Nalgene bottle, a bike pump, and tubing.
- The bike pump fed air into the bottle while a tube at the bottom fed water in, letting the team test early buoyancy concepts.
- Gillham describes it as an example of the company’s approach of testing early and often with cheap, basic prototypes before building more advanced versions.
