Sure, the towers may not be that advanced, though I bet they're optimized extensively for cost. It is the blades that I'm thinking of. They have to be light and strong, which aren't particularly new requirements, but I bet the scale adds challenges of its own relative to aircraft wings. Also, I hear wear on the gearboxes for these things are a major pain, so I bet they are pretty advanced as well.
- froindt 10y agoI'm an industrial engineer who deals with manufacturing. There's a ton that goes into the blades. Going higher up yields more energy, but the width of the blades are at the limit for transportation under highway bridges. With every rotation, the blade flexes know force at the bottom, high at the top. The materials are really advancing and the efficiency is improving. Cost is the killer of so many renewable energy sources. There is tons of optimization going on for cost.
