FloWave Ocean Energy Research Facility demonstrates the wide variety of waves it can generate. The water spouts are particularly impressive. Located at the University of Edinburgh, the 82-foot diameter tank features an unusual circular design that allows waves and currents to be directed in any direction. A ring of 168 wave generators line the edge of the tank, while 28 flow-drive units can generate currents of over 13 MPH. The tank is primarily used to test scale models of devices intended for use in water.
