Golubović and Knudsen have introduced the Rotating Space Elevator (RSE), a rotating system of a floppy string that forms an ellipse-like shape. Unlike the traditional Linear Space Elevator (LSE) made of a single straight cable at rest, the RSE rotates in a quasi-periodic state.

“The idea came by itself,” Golubović told PhysOrg.com. “I was thinking how to make things move easily and quickly up the traditional Tsiolkovsky-type space elevators. In my kitchen, I was mixing coffee in my cup too vigorously and the centrifugal force on the rotating coffee won over gravity to make some of the coffee lift and splash out the cup. This was my ‘eureka’ that lead to adding a similar conceptual feature to the old space elevator idea…
