In this episode of Earthlings 2.0, we chat with Rob Alexander, CEO of AlumaPower, about a new way to generate clean, on-demand electricity using recycled aluminum. AlumaPower’s galvanic aluminum-air generator releases the energy already contained within aluminum through a chemical reaction with air and water — producing zero-emission power at the point of use and a reusable byproduct. We discuss how the company overcame the chemistry hurdles that held back aluminum-air systems for decades, the path to commercialization, and why aluminum could emerge as a global, circular energy carrier.Key Points:<ul><li>Recycled aluminum as fuel – The system extracts stored energy from low-purity scrap aluminum, avoiding landfill and turning waste metal into a clean power source.</li><li>Backup power focus – Early deployments target data centers and other critical infrastructure where reliability, quiet operation, and reduced emissions replace diesel generators.</li><li>Modular scalability – Each cell generates 150 watts, stacking into containerized systems for megawatt-scale power; commercial launch planned for 2026.</li><li>Rob Alexander, CEO of <a href="https://www.alumapower.com/" rel="noopener noreferrer" target="_blank">AlumaPower Corporation</a>, <a href="https://www.linkedin.com/in/rob-alexander-8b89b8b/" rel="noopener noreferrer" target="_blank">LinkedIn</a></li><li>Lisa Ann Pinkerton, Earthlings 2.0 Host, CEO of <a href="https://technica.inc/" rel="noopener noreferrer" target="_blank">Technica Communications</a>, and Founder of <a href="https://www.womenincleantechsustainability.org/" rel="noopener noreferrer" target="_blank">Women in Cleantech and Sustainability</a></li><li><a href="https://www.linkedin.com/in/lisaannpinkerton/" rel="noopener noreferrer" target="_blank">LinkedIn</a></li><li><a href="https://earthlingspodcast.com/episodes/99-beyond-lithium/" rel="noopener noreferrer" target="_blank">Episode #99 – Beyond Lithium: How Air, Water, and Rock Could Power the Grid with Hydrostor</a></li></ul> 🚀 Calling all Earthlings…&nbsp;&nbsp;Visit our <a href="https://earthlingspodcast.com/" rel="noopener noreferrer" target="_blank">website</a> for more episodes!Sign up to our <a href="https://theearthlingspodcast.substack.com/" rel="noopener noreferrer" target="_blank">newsletter</a> for the latest news on the most exciting technology and research shaping our futures!&nbsp;We want to learn more about you!
