Riblet Coating is a surface coating that is applied to wind turbine blades. The small riblets in the coating mimic shark scale denticles, which help to reduce drag and increase lift. This allows the wind turbine to operate with the same effectiveness at lower wind speeds, while also reducing noise. This is why golf balls with surface texture dimples travel much farther than ones that are smooth. And why birds have fluffy feathers. A thin merino wool sweater will breath and reduce drag to a noticeable amount. Test it sometime on a windy day. At 2PM here in Coastal N. Cal it was 61 degrees and in Quebec Canada it was 75. As I head out for a small ride gusts are hitting 40 Mph with trees coming down. Invigorating.
