Kirk Sorensen stumbled across thorium while doing research on how to power a lunar community. Thorium is a cleaner, safer, and more abundant nuclear fuel—one that Kirk believes will revolutionize how we produce our energy.

Kirk Sorensen began his work with thorium while working as an aerospace engineer at NASA. In 2010, he left NASA to work as the chief nuclear technologist at Teledyne Brown Engineering. In 2011, he founded Flibe, a company focused on developing modular thorium reactors.
