Find out more about this book: www.cambridge.org/WindTurbines Transcript: 00:00 – 3:05 - Introduction 3:05 – 10:14 Presentation begins, first slide (Wake Velocity and Turbulence) 10:14 – 16:31 Technology Shifts 16:31 – 20:35 Direct Drive and Permanent Magnet Generators 20:35 – 20:49 What are the benefits of variable speed operation? What limits the rotor speed range? (left to answer in the Q&A) 20:49 – 23:33 Wind Power ownership can be at many levels. Who owns, who pays, who benefits? 23:33 – 25:30 Q&A Section: First Comment: You may also reduce the rotor thrust of the front turbine a bit in order to reduce the wake effects downwind 25:30 – 28:24 Second Question: With the Biden administration signalling an interest in ramping up investment in wind power in the USA, what lessons do you think can be learned from the development and rollout of existing European wind energy infrastructure? 28:24 – 29:10 Third Question: Simple explanation for how power depends on diameter and the cube of windspeed? 29:10 – 31:12 Fourth Question: With COP26 underlining the need for urgent decarbonisation of energy networks, what do you see as the biggest contemporary barriers to more widespread adoption of wind power generation, and do you think these hurdles will remain the same in the future? 31:12 – 33:40 Fifth Question: The farm turbine has a small wheel for steering into the wind; how is this done with the big turbines, I don't see a steering apparatus. 33:40 – 35:09 Sixth Question: Driving down the road recently I passed what looked like a Savonius Rotor perhaps powering a traffic counting device or some such. Is any work being done on vertical axis turbines in particular for small applications? 35:09 – 37:32 Seventh Question: From your perspectives, are there unique issues/problems associated with floating wind technologies? 37:32 – 40:21 Eighth Question: What technological advances do you see powering future developments in wind energy? 40:21 – 42:53 Ninth Question: How to design a wind farm collector system to minimize cable length? 42:53 – 46:28 Tenth Question: Could floating wind turbines be place inside a caisson to reduce wave motion? 46:28 – 49:25 Eleventh Question: Forecasting output power is increasingly important. What approaches in windturbine/windfarm design could you think of to improve this forecasting? 49:25 – 52:40 Twelfth Question: What do you see as the two most distant specialist areas in wind energy, and how does your textbook help to bring together these distinct multi-disciplinary areas? 52:40 – 53:37 Thirteenth Question: What was your favourite chapter of the book to write? 53:37 – 54:00 Fourteenth Question: Weather is a complex system, there will be an upper limit to the efficiency of forecasts. We might be there already. More sensible would be to work on harvesting the energy during the good times. 54:00 – 55:39 Fifteenth Question: What are the most significant engineering challenges involved in wind turbine design and installation? 55:39 – 57:55 Sixteenth Question: Lower power capacity, no straight lines in wind farms? 57:55 – 58:30 Round up & Thanks/END
