Coiling up extension cords by hand is tedious. Spring-activated spools aren’t much better; the mechanisms break easily and can cause violent snapback at the end of the cord. Engineers at Texas-based Great Stuff motorized the entire process. Using a combination of sensors and circuitry, the RoboReel neatly winds 50 feet of cable in 10 seconds, saving time and frustration.
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.
