A miniature magic carpet made of plastic has taken flight in a laboratory at Princeton University.
The 10cm (4in) sheet of smart transparency is driven by “ripple power”; waves of electrical current driving thin pockets of air from front to rear underneath. The prototype, described in Applied Physics Letters, moves at speeds of about a centimetre per second.
Improvements to the design could raise that to as much as a metre per second.
