Systems and methods for personalizing prosthetic and orthotic devices are disclosed. The body portion defines a support member and a flange extending from the support member. Applicants’ preferred MEWT embodiment comprises: an aerodynamically contoured turbine shroud with an inlet; a ring of stator vanes; a ring of rotating blades in line with the stator vanes; and a mixerejector pump to increase the flow volume through the turbine while rapidly mixing the low energy turbine exit flow with high energy bypass wind flow.
