Unique screw-like tidal wave power generator close to real-world deployment

A unique screw-like tidal wave power generator developed by UK-based Spiralis Energy is nearing real-world deployment. Recent computational fluid dynamics analysis of a quarter-sized test rig showed results within 1.5% of actual performance, validating the technology. The full-size 52-foot converter is expected to generate over 250 kW of power. Spiralis aims to supply 11% of the UK's annual energy demand using this sea-based renewable energy source, which is made from recycled plastic and designed to avoid harming marine life. The modular, 3D-printed design allows for easy repairs using local facilities.
