Hydrokinetic Energy Harvesting System for Human‑Powered Watercraft

Hydrokinetic Kayak Energy System
Project Type: Renewable Energy & Small-Craft Power System
Status: Feasibility Validated | Design Completed | Preparing for Prototype

Overview
This project introduces a compact hydrokinetic energy system designed to generate electricity from water flow during kayak operation.
The concept integrates a retractable helical turbine into the watercraft, converting motion through water into usable electrical energy to power onboard devices such as lighting and electronics.

Concept
The system is designed to operate efficiently at low water velocities, with a retractable mechanism ensuring minimal drag when not in use.
By enabling onboard energy generation, the solution provides a self-charging capability without reliance on external power sources.

Key Advantages
• Generates renewable energy during normal kayak use
• Retractable design to maintain performance and minimise drag
• Independent onboard power for lighting and devices
• Suitable for recreational and professional applications

Applications
• Recreational kayaking
• Marine research and exploration
• Small commercial watercraft
• Off-grid marine operations

Development Stage
The project has completed design and feasibility validation, with prototype development planned as the next phase.

Investment & Project Value
Estimated Investment Required (Prototype Phase):
£40,000 – £80,000
Projected Development Value:
£150,000 – £400,000

Commercial Potential
Growing demand for autonomous and sustainable marine systems presents strong opportunities for integration into next-generation self-powered watercraft across recreational, research, and commercial sectors.

Collaboration Opportunity
Open to collaboration with manufacturers, marine technology companies, and innovation partners to develop and test a working prototype.
