Saul Griffith om drager som fremtidens vedvarende energi

Kites, once tools of flight pioneers and childhood play, are being reinvented as powerful generators of renewable energy. A single kite smaller than a piano can already power several homes, while larger airborne wind machines promise to reach stronger winds at high altitudes, where turbines cannot go. With high-altitude wind holding enough energy to supply humanity many times over, this playful technology could fuel a bold new era of clean power. History shows that audacious ideas, like mass-producing airplanes in World War II, can reshape our world when pursued with vision and teamwork.
