Check out this YouTube video post, about the escalators? Maybe a silly post, but I thought it was cool. The escalators in the Berlin Convention center are on auto pilot, based on motion. As you approach the escalator, it happily comes alive to serve you. When there is no one on the escalator it turns it self off, presumably to save power.
In the states, if you see an escalator that is stopped, you automatically look for stairs, or an elevator to change floors, especially if you’re going up.
This seems like a great/simple way to save a lot of energy!
Good job – whoever thought of that first 🙂
