Direct way to space

Eurobricks user hknssn has published his newest and awesome creation based on two EV3 bricks. He “simply” built a space elevator. More or less. Basically the robot builds a tower. Theoretically to infinity. One EV3 brick takes care of supplying the builder with modules, and the builder takes these modules and puts them on top of the tower. But I can describe this as much as I want, because seeing this masterpiece in action is better than any words that I can find.

This creation imposes a lot of interesting questions. Like how long does it take to create a specific height? How long can it run on a single batch of batteries? How many pieces does it take to reach space? What is the practical height that this creation can reach before the laws of physics shatter it to bits? Questions over questions.

If you come up with a good question, please post it in the comments!
