If we could somehow capture even 0.1% of the kinetic energy of the ocean we could meet the entire power demand of the world. If fact we would exceed it by a factor of 5!
Here is a promising tidal energy conversion technology named Wave Star that is worth exploring. This Danish invention features kinetic energy floats as seen in the giff below. This kinetic energy of the wave motion is transferred using hydralic pressure to a central generator system which produces clean electricity.
Making clean electricity from the motion of the waves
The wave system is said to be upgradable to include wind and solar power if you so choose. Wave Star is projected to be on the market in 2017. Each Wave Star station has a capacity of 6 Mwatts which could power up to 4ooo homes.
Continous wave energy is transferred to the hydraulic piston of the Wave Star System
Any technology that intends to harvest wave or tidal energy over the period of many years must meet strict criteria. The technology must be incredibly robust,scalable and easily maintained. The wave energy industry is only in the early stages of development. Other Technologies such as wind,solar,biomass and biofuel are far ahead in maturity as well as readiness for commercialization.
The Wave Star System
Companies like this will change the world. Entreprenuers will eventually find a winning wave energy conversion device that will stand up to mother nature and economics.
