This is the PTO stage 2 project summary report for the Umbra Cuscinetti ReBaS Generator project. The project demonstrates the advantages of using a reciprocating linear drive featuring recirculating ball screw technology to convert energy from ocean waves to electricity at a high efficiency.

Recirculating ball screw drives are already widely used and well established in other sectors, e.g. robotics, machining tools or aircraft control systems. In the ReBaS Generator project, direct drive technology is combined with a pivoted buoyant wave absorber in controlled test conditions to transform wave power into linear force, and from there to useful electrical power.
