A physics prodigy who co-founded a company aiming to revolutionize energy storage by compressing air in water.
Danielle Fong's trajectory was anything but conventional. Entering university at just 12, she eventually left a PhD program at Princeton to dive into the urgent problem of renewable energy storage. In 2009, she co-founded LightSail Energy, championing a novel concept: storing energy by compressing air in the presence of water mist, a method intended to be more efficient and scalable than batteries. While LightSail's commercial journey faced hurdles, Fong's vision cemented her as a bold thinker in cleantech. Her work continues at LightCell Energy, pursuing next-generation solutions for a carbon-free grid, driven by a belief that physics and entrepreneurship must collide to solve climate change.
1981–1996
The first digital natives. Grew up with the internet, came of age during 9/11 and the 2008 crash. Highly educated, deeply indebted, slower to marry and buy houses. Redefined work, identity, and what it means to be an adult.
Danielle was born in 1987, placing them squarely in the Millennials. The events that shaped this generation — the internet revolution, 9/11, and the 2008 financial crisis — shaped the world they entered and the choices available to them.
