Professor Scruggs is developing advanced components for wave and tidal energy systems

The Energy Department recently selected four entities to receive $7.4 million to spur innovation of next-generation water power component technologies, designed for manufacturability and built specifically for marine and hydrokinetic (MHK) systems.| Short Read

Associate Professor Jeff Scruggs is a participant in one of the projects. This project, which focuses on advanced controls, will develop an optimal control system that predicts ocean conditions and adjusts device settings accordingly to optimize power production for three different wave energy converter (WEC) devices:

(1) the OE buoy developed by Ocean Energy USA

(2) the Surge WEC device developed by Resolute Marine Energy, and

(3) the Wave Carpet developed at CalWave (UC Berkeley).

Device performance improvements will be validated through wave-tank testing and one final full-scale test.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
