In this episode of the Fluid Mechanics 101 Podcast, I discuss challenges and opportunities in Tidal Stream Energy with Dr Chris Vogel. Dr Chris Vogel is a departmental lecturer at the University of Oxford in the Department of Engineering Science. His research focusses on Wind and Tidal Turbine energy extraction. 
Some useful timestamps for the discussion are: 
02:25 An Introduction to Dr. Chris Vogel and Tidal Stream Energy
06:50 What is tidal range / barrage technology? 
12:05 What are tidal stream turbines and what are some of the challenges with this technology? 
13:45 What are the different options for installation of tidal stream turbines? 
16:40 Some examples of sites where tidal stream turbines are already installed and operational.  
18:53 A discussion of challenges faced by tidal stream turbines. 
24:00 The effect of blockage on tidal turbine rotor loading and design. 
29:47 One of the challenges faces by tidal stream turbines: blade deformation 
35:17 Investigating tidal turbine blade deformation with a fluid-structure interaction analysis
41:49 Dr Chris Vogel's roles and resposibilities as a lecturer at the University of Oxford. 
46:20 The interface between research groups, academia and industry. How large is the tidal energy community?
54:37 What contribution can tidal stream energy make to a low-carbon electricity network and help to meet climate change targets? 
01:00:44 Closing thoughts
