Resumen:
Una empresa italiana ha desarrollado un nuevo sistema para capturar energía a partir de corrientes de ríos y mareas que combina alto rendimiento, rentabilidad y simplicidad. El sistema consiste en una turbina cinética que se sumerge en corrientes de agua y se mantiene en equilibrio por la acción de un deflector central y un cable anclado a la orilla. El tamaño y orientación del deflector se definen en función de las condiciones de funcionamiento y de la posición de equilibrio deseada. La empresa busca socios interesados en continuar con el desarrollo para construir un generador dentro de la máquina, sin estructura independiente.

Permanent magnet generator for machines producing energy from renewable resources
Summary:
An Italian company has devoloped an innovative system for the collection of energy from river and tidal currents, combining high performance, cost-efficiency and simplicity. The system consists of a kinetic turbine able to be immersed inside water currents and kept in equilibrium by the action of a central deflector and a cable anchored to the shore. The company is interested in joint further development to built a generator inside the machine, without any stand alone structure or box.
Description:
An hi-tech Italian company has devoloped an innovative system for the collection of energy from river and tidal currents, combining high performance, cost-efficiency and simplicity. The System consists of a kinetic turbine able to be immersed inside water currents and kept in equilibrium by the action of a central deflector and a cable anchored to the shore. The size and the orientation of the deflector are defined according to the working conditions and desired equilibrium position. The turbine and its components have been designed assuming that the machine will always work under maximum power coefficient conditions. This implies a variable rotational speed, so the use of an inverter becomes mandatory. Preliminary performance estimations show that the system can provide electrical power of about, with 43% efficiency when the system works under optimal conditions.
The company is working to improve the system with the implementation of a permanent magnet generator inside the machine. In fact, the machine has a unique design and the standard generators on the market don't fit it. The special application needs a generator built in the machine, without any stand alone structure or box: the main components, coils and magnet, could be standard, but designed right for that application, togheter with all needed parts and connections, "taylor made" for the machine. The generator shall be also waterproof (for rivers and sea).
The machine solutions are patent covered, in advanced development phase for the mechanical side and needs to be implemented just for the electrical part: an initial static prototype has been built.
The company is looking for a joint further development to built a generator inside the machine, without any stand alone structure or box.
The company offer a long term development collaboration in order to design and built the whole machine ready for the market.
Advantages and Innovations:
The system is disruptive in terms of installation and operational costs, given the fact that the turbine is kept in equilibriumusing an extensible cable connected to the shore. As a result, all operations can be carried out from the coast and the civil works needed to support the turbine can be executed in a cost-effective and simple way. In addition, the system overcomes the frequent environmental problems connected to the presence of protected species as states a European Community Law, which forbids any interference with the seabed (such as electric cables lay out and foundations).
Furthermore, the turbines are adaptable to multiple site conditions and can be optimized considering the site's bathymetric profile and flow speed patterns.
Due to its special hydrodynamic features, the system stands in equilibrium using a structure subjected to exclusively tensile stresses, unlike other tidal technologies that have to cope
with flexural loads due to the action of the current's drag forces.
This fact results in a significant cost reduction (both in terms of materials, installation works and manpower needs) and an enhanced environmental compatibility compared to existing technologies.
In addition, the use of traditional and onshore-based equipment, both for installation and maintenance operations, makes the system significantly competitive in the Renewable Energy market (in terms of capex and opex) and highly compatible with the surrounding environment.
