Dr. Maria Telkes- First Solar-Heated House

Dr. Mária Telkes, an American biophysicist designed the world’s first fully solar-heated residence ‘Dover Sun House’ in an alliance with architect Eleanor Raymond in the year 1948. The house was located at Dover, Massachusetts where it utilized 18 large south-facing windows for capturing solar energy, stored in 21 tons of Glauber’s salt (sodium sulfate).

This creative approach offered heat for up to ten days with no sun exposure. However, the system came across number of challenges in due course. Yet, the project was a cutting-edge manoeuvre in the usage of solar energy that earned Dr. Maria a title of ‘Sun Queen’ for her endowments to renewable energy.
