"In the grand scheme of things, we're still in the early stages of wind power generation, but even so, there are still many, many wind turbines already installed and generating power. When new technological advances come along like new turbine designs or tweaks to the blades or motors that can increase power generation, replacing entire wind turbines would be very costly. Because of that, Siemens has developed a set of wind turbine blade attachments that increase power generation without having to fully replace any part of the turbine.
The coolest part of these add-ons? They're inspired by dinosaurs.
