Bright Harvest premiered to a packed audience at Caltech, showcasing a major scientific milestone in space-based solar energy. The film follows three Caltech scientists whose team achieved the first successful demonstration of space solar energy beamed wirelessly to Earth — proving that space-based solar power is rapidly emerging as one of the most promising breakthroughs in the global shift toward clean, continuous power. Instead of relying on ground-based solar farms limited by weather, atmosphere, and nightfall, this technology places large solar arrays in space, where they collect sunlight 24 hours a day.

​Their research includes modular satellite architectures, ultra-light photovoltaic structures, advanced wireless power transmission, and innovative deployment systems capable of creating massive orbital solar power stations. Their work has captured global attention, generating articles, scientific discussions, and international interest in the potential of solar power satellites.
