Dynamic Tower Skyscraper: Every Floor Self-Rotates, Powered by Wind and Sun

Italian architect David Fisher is building his first skyscraper, the Dynamic Tower, and it happens to be one of the most ambitious construction plans since the Pyramid of Khufu. Every floor of the 80-story self-powered building rotates according to voice command, and nearly the entire structure of the $700 million building is pre-fabbed. I caught up with the architect in New York, and he blew my mind again and again.
