A public lecture by Professor Alistair Borthwick, FICE, FREng, FRSE

Over the centuries, the tides and, more recently, their power potential have attracted much scientific interest. For example, in 1665, Sir Robert Moray authored a publication in the Philosophical Transactions of the Royal Society on “A Relation of Some extraordinary Tydes in the West-Isles of Scotland”. This lecture will take a historical journey through the scientific developments in our understanding of tides and their power potential, commencing at Ahmedabad in Ancient India, passing through the Dark and Middle Ages, the pre- and post-Newtonian periods, and finally taking us to modern approaches to assessing tidal stream power for the Pentland Firth, Scotland, and Raithlin Island, Ireland. The final part of the lecture will consider the use of contra-rotating vertical axis turbines for extracting green energy from rivers and tides.

Alistair Borthwick is an Emeritus Fellow of St Edmund Hall Oxford, Emeritus Professor at The University of Edinburgh, Visiting Distinguished Professor at Shanghai Jiao Tong University, and a UWA Institute of Advanced Studies Visiting Fellow.
