Big or small, turbine blade tips have about the same linear velocity, so the longer the blade, the less the rotational speed (since v = rω). These turbines are about 96-100m in diameter. The first ones I worked with were about ⅓ of that, and the (quarter century old!) one on Fair Isle is about ⅙. They’re slow only because they’re big.

I'm assuming it indicates efficiency, right? Rob Excuse my ignorance, but is slow turning good? I’m assuming it indicates efficiency, right?
