AI Technical Summary

Benefits of technology

"The patent describes an electro-hydrodynamic (EHD) system for extracting energy from wind. The system includes an upstream collector that induces an electric field, an injector for introducing particles into the electric field, and a downstream collector. The particles are introduced into the electric field and wind drag on them is at least partially opposed by the force of the electric field. The system can be adjusted to extract energy from wind in different directions and at different distances from the collector. The patent also describes an injector for producing particles in the EHD system and a method of generating electricity using the system. The system can be integrated with a display for visualization and the patent also describes a method of displaying a message using the system."

Problems solved by technology

Similarly, numerous means of forming an electric field with the objective of providing a charge on a droplet are known, however, specific means of designing such an electrode to minimize losses in an EHD wind system have not been identified.

Embodiment Construction

[0044]As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Additionally, the use of “or” is intended to include “and / or”, unless the context clearly indicates otherwise.

[0045]Provided herewith are modifications of electro-hydrodynamic (EHD) wind energy systems that provide improved efficiency and greater control of system components as well as provide alternative configurations for these systems. As elaborated in PCT Patent Publication WO 2009 / 094441, an EHD wind energy system requires the following:[0046]The separation of positive from negative charge within an otherwise neutral fluid;[0047]The deposition of a charge on water droplet;[0048]The separation of the charged water droplet from the opposite charge by wind; and[0049]The collection of the opposite charge to do work

[0050]Opposing charges are drawn towards one another. The force between opposing charges can be defined by an ele...

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 214,852, filed 29 Apr. 2009, U.S. Provisional Application No. 61 / 247,481, filed Sep. 30, 2009, and U.S. Provisional Application No. 61 / 303,302, filed Feb. 10, 2010, all of which are incorporated by reference herein in their entirety.FIELD OF THE INVENTION[0002]This invention relates to electro-hydrodynamic wind energy conversion systems.BACKGROUND OF THE INVENTION[0003]Electro-hydrodynamic (EHD) wind energy conversion is a system where blowing wind acts on a spray of electrically charged droplets. These charged droplets are separated from their counter-charged source by the wind's energy. This negatively charged side can be connected to a load to produce a working current. See, e.g., PCT Patent Publication WO 2009 / 094441, filed Jan. 22, 2009, and U.S. Provisional Patent Application No. 61 / 247,481, filed Sep. 30, 2009 for examples of EHD wind energy conversion syste...
