Tomás Saraceno: Would you live in a floating city in the sky? (with English subtitles) | TED

(Full English subtitles are available for this talk -- click the CC button in the bottom right of your screen to turn subtitles on.)

In a mind-bending talk that blurs the line between science and art, Tomás Saraceno exhibits a series of air-inspired sculptures and installations designed to usher in a new era of sustainability, the "Aerocene." From giant, cloud-like playgrounds suspended 22 meters in the air to a balloon sculpture that travels the world without burning a single drop of fossil fuel, Saraceno's work invites us to explore the bounds of our fragile human and terrestrial ecosystems. (In Spanish with English subtitles.)
