Sometimes the simplest ideas are the best. A couple of weeks ago, the Technion Institute in Israel held a Space Elevator competition (I’ve previously posted about this competition here and here). The winner used the inner workings of an electric screwdriver to power his Climber.
Details can be found here. Money quote from the winner: “The idea of basing the engine on an electric screwdriver we borrowed from the world of manufacturing plastic pipes using plastic extrusion, in which raw plastic material is melted and formed into a continuous profile,” said Atzili. “In short, it’s an idea that came to me originating from my experiences working in the plastics industry.”
Congratulations to Technion and to the winners!
