Saturday, December 15: I leave for Tokyo in two days. The assignment: Ride the world's fastest roller coaster—called Dodonpa—which has been tested at 115 mph. Dodonpa is powered by three 800-horsepower air compressors. Air is filtered and dried, then stored in four 40-foot-high tanks before it catapults the cars down the track.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
