Harnessing the Power of Moving Water

Scalable, predictable, environmentally responsible electricity from rivers, tidal channels and ocean streams — without the infrastructure demands of conventional hydroelectric systems.

Flow Acceleration Technology

Proprietary technology increases velocity through the turbine zone, improving energy capture at a wider range of flow speeds. CFD simulations and in-water testing validate performance across multiple scenarios.
