Make Sunsets is building a prototype solar‑geoengineering approach it calls albedo enhancement: reflective, biodegradable high‑altitude clouds intended to reflect sunlight and cool the planet. The company plans near‑term tests consisting of latex weather‑balloon launches that will release 10–500 grams of sulfur dioxide and publish flight data. It is also selling "cooling credits" starting at $10 for companies to offset emissions via sunlight reflection. Make Sunsets has raised at least $500,000 in venture capital and incorporated on Oct. 1, and brought on co‑founder Andrew Song. Founder Luke Iseman is operating from Baja, Mexico and has a background building hardware projects and deployments. The company frames its work as a rapid, low‑cost experiment to explore albedo approaches while acknowledging scientific and governance controversies.
