In 1948, scientist Mária Telkes, known as “The Sun Queen,” built a revolutionary home in Massachusetts that stayed warm through freezing winters using only sunlight and salt—no gas, no electricity. Partnering with architect Eleanor Raymond, she developed the Dover Sun House, which stored solar energy in Glauber’s salt (sodium sulfate), a phase-change material that captured and slowly released heat. It was one of the world’s first passive solar-heated homes—and it worked, even on cloudy days.

But this wasn’t just about tech—it was about freedom. Telkes believed energy innovation should serve people, especially women burdened by smoke-filled kitchens and unreliable heating. She went on to invent solar ovens, desalination kits, and off-grid systems that empowered communities worldwide. With over 20 patents and a legacy that reshaped green technology, she proved that clean energy isn't just a future goal—it’s been possible for decades.
