How to Build a Space Elevator

An elevator to space isn’t such a crazy idea, according to a team of experts who have written a detailed 300-page report on how to build one. In a nutshell, to reduce the cost and energy of getting from Earth to space, Motherboard reports that a supertough, nearly 100,000-kilometer-long cable equipped with robotic “climbers” needs to be anchored near the equator. The researchers say current rocket technology used to get to space isn’t very practical—it spews a bunch of chemicals into the atmosphere on liftoff, and it can’t carry much cargo—so an elevator to the heavens just makes more sense.
