Goal
Convert ocean wave energy into electrical power.
Problem
Need for renewable, environmentally friendly energy sources to replace fossil fuels; capture the abundant energy of ocean waves.
Concept Summary
A buoy-mounted spinning gyroscope is driven by the oscillating motion of ocean waves. The gyroscope's precession creates a continuous torque that is transferred via a crank or coupling mechanism to an electromagnetic motor-generator, producing electricity.
Principles
- Gyroscopic precession
- Conversion of oscillating torque to continuous torque
- Electromagnetic induction
Scientific Domains
Materials
- Steel (flywheel/gyroscope)
- Copper wire (generator windings)
- Aluminum (crank and housing)
- Plastic or foam (buoyancy hull)
- Electronic components from salvaged tape recorder and answering machine
Mechanisms of Action
- Wave-induced oscillating motion causes gyroscope precession
- Precession drives a crank or coupling that rotates a motor-generator
- Rotating generator produces electrical power
Energy Sources
Applications
- Off-shore renewable electricity generation
- Coastal micro-grids
- Remote or island power supply
Experimental Evidence
Prototype testing showed measurable electrical output as illustrated in figures 7-10 of the patent documentation.
Replication Status
Prototype built and tested by the inventor; no independent replication reported.
Limitations
- Dependence on sufficient wave activity
- Prototype scale; durability of moving parts in marine environment
- Lack of demonstrated long-term reliability
- Unclear cost-effectiveness at commercial scale
