Engineer Visualizes New Tidal Power Concept in Scottish Highlands

Immersive Design Experiment
In a remote stretch of river in the Scottish Highlands, civil engineer David Mummery entered the fast-flowing water more than ten years ago to feel the forces that shape river dynamics. He tied a cord across the channel, swam into the current, and allowed the turbulence to rush over him while keeping his head submerged. The physical sensation of the water’s power informed his mental model of how a turbine could interact with such an environment, a method he describes as “feeling the water” rather than relying solely on calculations.
Concept for Small-Scale Tidal Generator
Mummery’s immersion led him to sketch a compact tidal energy device intended for deployment in coastal settings. The design emphasizes direct interaction with rapid water flow, aiming to capture kinetic energy without the large infrastructure typical of conventional tidal farms. By situating the turbine beneath the water surface, the concept seeks to harness turbulence efficiently while minimizing visual and ecological impact.
Potential Benefits for Coastal Communities
If realized, the generator could provide a renewable power source for isolated or small coastal villages that lack access to large-scale grid connections. The modest size of the system suggests lower installation costs and easier maintenance, potentially enabling communities to achieve greater energy independence. Proponents argue that such technology could complement existing renewable portfolios, especially in regions where wind or solar resources are limited.
Outlook and Next Steps
Mummery’s idea remains at the prototype stage, with further engineering analysis and field testing required to validate performance and durability. Future development will likely involve collaboration with marine engineers, local authorities, and potential investors to move from concept to pilot installations. The approach underscores a broader trend of using hands-on experimentation to inspire innovative solutions in renewable energy.
