General information
- Short Summary
- A Spanish research team specialized in the field of Fluid mechanics, has developed and patented a device that allows generating electrical energy from the wind at low wind speeds and with low both acoustic and visual impact. A company willing to implement and commercialize the technology through a license agreement or a technical agreement is sought.
- Full Description
-
The Andalusian research team belongs to the University of Malaga and works in the field of fluid mechanics.
Some of the activities carried out by the research group are focused on the field of wind energy, which is an abundant, renewable and clean resource that helps reduce greenhouse gas emissions by replacing energy sources based on fossil fuels. Particularly they have developed and patented a system that solves the problems of visual impact, radar interference, shock waves at the tips of the blades or sound emission that current large two- and three-blade wind turbines have.
Backgroud: Of all the types of renewable energy, one of the most widespread in the world is wind energy. Its paradigmatic example for the massive generation of electrical energy from the movement of the wind is the three-blade wind turbine. However, these devices have a number of drawbacks.
The present invention is framed within the field of devices for energy conversion; more particularly, devices that convert wind energy into electrical energy.
The invention provides a device that takes advantage of the aeroelastic instabilities generated by the wind in a very thin horizontal sheet supported elastically by a vertical shaft attached in its upper part to a NACA type profile, integral with the sheet at its leading edge, and whose part The lower part is arranged to be able to move with respect to a fixed base anchored in the ground. The energy of the wind is transformed by the oscillation of the blade into vertical oscillatory movement of the shaft, which in turn is converted into electrical energy.
Thus, there is a need in the present technical field to develop a different alternative to convert wind energy into electrical energy, but overcoming the difficulties mentioned above.
Companies in the energy sector that wish to implement and commercialize the technology via license agreement or want to explore the new possibilities in the field of devices for energy conversion through technical agreement are sought. - Advantages and Innovations
-
The present invention addresses the design, evaluation and manufacturing proposal of a device for energy conversion,
The main novelty lies in the structure, which is made up of two main parts:
a) the support in its upper part would have an aerodynamic shape consisting of a NACA profile. Said support would have a cylindrical shape to house both a spring and the generating motor and could rotate to reorient with the direction of the wind;
b) a large sheet of a very small thickness/length aspect ratio.
Both parts would be made of light and flexible materials such as fiberglass, Kevlar, etc. The support in its vertical movement induced by the wind would be amplified thanks to the resonance between the flexibility of the sheet and the spring included in the support.
The generation of electrical power would be possible in a range of wind speeds below 5 m/s, where most current wind turbines have problems working.
On the other hand, it solves the problems of visual impact, radar interference, shock waves at the tips of the blades or sound emission that current large two- and three-blade wind turbines have.
Finally, it would be much more harmless to birds. - Stage of Development
