Elements of Tidal-Electric Engineering

ROBERT H. CLARK, OC, MENG, PENG, has been studying and working with tidal-electric power since the late 1950s, beginning with his work with the International Passamaquoddy Engineering Board. As chief hydraulic engineer with Canada's Department of Energy, Mines and Resources, he led the research into the viability of exploiting the Bay of Fundy's tidal resources. Mr. Clark has been appointed an Officer of the Order of Canada (OC).
