Mária Telkes built a house heated by stored sunlight. ☀️

Mária Telkes built a house heated by stored sunlight. ☀️ . . . In 1948, Telkes and architect Eleanor Raymond completed the 2-bedroom Dover Sun House in Massachusetts. Solar collectors warmed tanks of Glauber's salt, which released heat after sunset. The system later developed problems—but it proved a home could bank summer-like warmth for winter nights.
