“The hard work and dedication of the brilliant scientists at Caltech have advanced our dream of providing the world with abundant, reliable, and affordable power for the benefit of all humankind.” — Donald Bren
A new documentary film highlights the ongoing efforts and breakthroughs of three Caltech professors in their quest to make space-based solar power a reality. In 2011, philanthropist Donald Bren provided a generous grant to Caltech which began the Space-based Solar Power Project. In 2023, the project, led by professors Harry Atwater, Ali Hajimiri, and Sergio Pellegrino launched the Space Solar Power Demonstrator into orbit, showcasing three technological advancements needed to make space-based solar power possible.
The Bright Harvest website details the story behind the Caltech Space-based Solar Power Project, along with ways to view the documentary.
