Niklas Roy is at it again. This time, he has created a machine that causes an elevator to call itself to the first floor when it is on the second, and vice versa, in order to endlessly waste energy. It even adds up the amount of wasted energy on a paper calculator roll, which it dumps in the trash.
“Perpetual Energy Wasting Machine” is a rope and pulley mechanism, installed in the staircase of the WRO Art Center in Wroclaw, Poland. The mechanism connects the sliding doors of the elevator in one floor with the elevator call button on another floor. Operating in two directions on the first and on the second floor, the contraption automatically moves the elevator cabin in an infinite loop between those two levels.
