A process assembly includes an air mover assembly having a rotor assembly with rotor blades extending from a rotor hub and configured to cause an air flow to move over at least a portion of a process device to facilitate a process. The process device includes at least one of a heat exchanger or a direct air carbon capture device. The air mover assembly may be a wind turbine air mover assembly including a wind turbine rotor assembly. Each rotor blade may include a body structure defining root and airfoil sections extending along respective first and second span portions of the rotor blade. A ratio between the airfoil profile chord and the profile thickness and a twist angle between the airfoil profile chord and a root profile chord of the root section may vary along one or more portions of the second span portion.
