Your Questions About Wind Turbine
Maria asks…
What physical principles are involved in the function of a wind turbine?
Part of Concept Design is to specify the physical principles involved in a design. For example, surface friction could be the physical principle behind brakes. What would the principle behind a wind turbine be? Fluid viscosity? Conservation of momentum?

Laura asks…
Why is high speed at low torque optimum for energy generation in a wind turbine?
I’m studying an article on wind turbines. The article says that for electricity generation, a wind turbine rotating at high speed providing a low torque is preferable to a turbine rotating at a low speed and producing a high torque. Can anyone explain why this is the case? Surely the speed could be altered easily using a sequence of gears before the generator?
