A preliminary design concept was then formulated by RTS and simulated utilising a number of mathematical models. Several in water test trials followed resulting in a solution that appeared simple and proven to work. RTS named this solution “Hydropower in Reverse.” This model is a moving turbine travelling in a different phase to that of the wave motion. The moving turbine rotates and spins whenever seawater is forced through the blades.

Here are a few examples where Goby® could be utilised:

• Sensor spreads for hydrographic and oceanographic monitoring.Traditionally these packages are powered using solar panels and batteries with all the limitations that this brings. By using subsea wave power generation, the range of sensors can be increased, and the surface buoys made smaller and lighter.
• Charging of subsea battery banks where Goby® would be able to provide battery pack charging and data communications to resident underwater drones.
• Further uses include observation of critical infrastructure where the Goby® Wave Charger is equipped with monitoring devices both above and below the surface, or function as a data interface hub for a network of subsea sensors.
