Ocean waves are bound to offer something, power-wise. And it seems that some specially made tubes can do just that, opening up a new area of probability as far as alternative energy generation is concerned.
With the aid of hydraulic pistons, the said tubes would be able to capture energy from Ocean waves. Inventor Sam Etherington is was somehow able to come up with a long chain of loose linked enclosed pistons which are able to generate energy as the said chain flexes.
The cylinders ride the peaks and troughs of waves, which spins concentric shafts working in pairs to push and pull hydraulic fluid (similar way to how a piston works). This double action then creates pressure which is stored in accumulators and released at a capped limit into a hydraulic motor.
