The renewable heating system right below your feet | Kathy Hannun

Of all the mundane yet astonishing marvels of human ingenuity, knowing what it takes to heat a room to a comfortable temperature is TED Fellow Kathy Hannun's favorite.

She takes us on a journey across the planet and under the sea to emphasize the dangers of modern heating, and offers a safer, planet-friendly alternative that taps into the geothermal energy right below our feet.
