From Battle-bots to the ocean floor, the skies over hostile territory to the surface of Mars, MODERN MARVELS® explores the remote control world. Travel back to 1898, when Nicola Tesla started a technological revolution by successfully controlling a six-foot long model boat using radio waves. From that humble beginning, the world of remote control has grown exponentially, with microwave, infrared and a host of other technologies expanding our virtual reach ever farther. REMOTE CONTROL shows how the various methods work and goes into the labs where scientists and engineers are developing the next generation of remote control devices, including a solar-powered helicopter that can fly up to 100,000 feet and remain there for months at a time.
