A revolutionary ocean wave power plant has been created, operating without the need for fixed structures or anchoring systems, offering a clean and sustainable solution.
The world is searching for renewable energy sources, and the ocean, with its vast potential, presents itself as one of the greatest promises. However, harnessing this resource is still a major challenge.
Most current technologies face efficiency limitations and high costs. It is in this scenario that Kinowave emerges as an innovation that can transform the way we generate electricity from ocean waves.
What is Kinowave?
Kinowave is an innovative system for converting ocean wave energy into electricity. Its main feature is the use of interconnected cylinders filled with fluid, which capture the movement of the waves in a highly efficient way.

Unlike other systems that rely on large fixed structures or anchoring systems on the seabed, Kinowave does not require these permanent infrastructures, making it a more economical and sustainable solution.
How does Kinowave work?
Based on Pascal's principle, Kinowave uses vertical cylinders connected by flexible tubes that float on the surface of the sea. Waves move these cylinders up and down, creating a relative movement of the fluid inside. This movement is converted into electricity by energy conversion mechanisms, such as Wells turbines, which are highly efficient at transforming dynamic movement into electrical energy.
This innovative system solves the complexity and cost of other solutions that rely on fixed and expensive anchoring systems, in addition to improving the efficiency of wave energy conversion.
The inspiration behind Kinowave
The idea of creating Kinowave came about when we realized the enormous untapped potential of waves, which could generate up to 41.300 MW of energy in India alone.
However, the difficulty of creating efficient relative motion between the waves and the energy capture systems was a challenge. Inspired by Pascal’s principle and ancient water leveling devices, Kinowave was designed and tested in a wave tank, where it was proven that the connected cylinders could generate the motion needed to capture the wave energy.
The development process
Kinowave’s development began with the ambition of creating a simple and efficient system. The first prototype used plastic bottles connected by tubes to validate the concept. Although promising, the flow of water between the tanks was slow.
As a result, the system was optimized, replacing plastic bottles with tanks and tubes of equal diameter, which significantly improved fluid flow.
Over the course of the process, the design was refined, and floats were added to convert the motion into energy. The system achieved an efficiency of over 65% in early trials, outperforming many existing wave power generators.
Collaboration with companies such as Mocean has resulted in the incorporation of Wells turbines, further increasing the efficiency of the system.
Kinowave's differences
Kinowave stands out for several reasons. Firstly, it eliminates the need for permanent structures on the seabed, which significantly reduces installation costs and complexity. Secondly, the efficiency of the system is much higher compared to traditional technologies such as Pelamis, which rely on inefficient hydraulic systems.
Furthermore, Kinowave’s design is modular and adaptable, making it easy to deploy in different ocean conditions. This makes it a viable solution for many regions around the world, with the ability to scale as needed.
Advantages over existing technologies
Compared to other wave energy technologies, Kinowave offers several advantages. It overcomes the problems of wave height and direction variations common in traditional systems. Its absence of anchoring to the seabed reduces the need for large, expensive and difficult-to-maintain infrastructure.
Unlike systems such as Point Absorbers or Attenuators, which can be expensive and inefficient, Kinowave offers a low-cost, high-efficiency solution.
It also solves the durability and mechanical complexity issues found in other wave energy conversion devices such as Oilseed Oscillation Converters.
The future impact of Kinowave
Kinowave aims to establish itself as an important solution in the transition to a more sustainable energy model. Among its objectives for the coming years are the validation of the Wells turbine prototype in a wave simulation tank and the manufacture of a 100-watt prototype for testing in real conditions in the ocean.
Furthermore, the goal is to scale the system to 10 kW within three years, which would be enough to power five homes, a crucial step towards the commercial viability of the project.
