This strikes me as a **very compelling** breakthrough with regard to coral reef restoration.
Dr. Thomas J. Goreau and his team received an award in the IDEAS Competition at MIT, Cambridge, MA for their tidal energy device which is used to re-establish dead coral reefs. The coral communities grow very quickly and can survive at higher water temperatures.
See the fascinating 3 min 40 sec video clip in which Professor Goreau eleoquently explains and illustrates the results of his research.
