ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to an apparatus for generating mechanical power and, more particularly, it relates to a column airflow power apparatus for generating mechanical power utilizing airflow through a column structure.
2. Description of the Prior Art
The generation of mechanical power plays a significant role in many areas of modern society. For example, generators, pumps, and industrial equipment require mechanical power to operate. Due to the critical role mechanical power plays in the successful operation of these devices and the shortage of energy from other sources, it is essential that each device receives efficient and effective power from the chosen source.
Heretofore, mechanical power devices often have relied upon fossil fuels, open blade wind sources, and/or hydro methods to generate power. These methods, however, are hindered by cost, shortages, environmental impact, maintenance issues, and/or outright failure.
Accordingly, there exists a need for an improved column airflow power apparatus for efficient and effective generation of mechanical power. Additionally, a need exists for a column airflow power apparatus which increases the velocity of airflow through the column structure by concentrating the airflow to a desired location. Furthermore, there exists a need for a column airflow power apparatus which increases the amount of airflow through the column structure by reducing the pressure of the air at the top of the column structure relative to the bottom of the column structure. Further yet, a need exists for a column airflow power apparatus which heats the air within the column structure reducing icing through the column structure, starting/inducing the airflow within the column structure, and increasing the amount of airflow through the column structure.
SUMMARY
The present invention is a column airflow power apparatus for creating mechanical power. The column airflow power apparatus comprises a column structure having an open first end and an open second end with airflow moving through the column structure from the first end to the second end. A rotatable blade is mounted within the column structure with the airflow rotating the rotatable blade. A power shaft is connected to the rotatable blade with the power shaft rotating with the rotatable blade. A rotatable turret device can be mounted to the second end of the column structure and an adjustable airfoil mounted to the rotatable turret. An air concentrator can be mounted within the column structure between the first end and the rotatable blade.
The present invention additionally includes a column airflow power apparatus for creating mechanical power. The column airflow power apparatus comprises a column structure having a first end and an open second end with the column structure having at least one slot nearingly adjacent the first end allowing airflow through the column structure from the first end to the second end. A rotatable blade is mounted within the column structure, the airflow rotating the rotatable blade. A power shaft connected to the rotatable blade with the power shaft rotating with the rotatable blade. An air concentrator is mounted within the column structure between the first end and the rotatable blade.
The present invention further includes a method for creating mechanical power from an airflow. The method comprises introducing an airflow through a column structure, concentrating the airflow to a rotatable blade, rotating the rotatable blade with the airflow, and creating low pressure at the airflow exit of the column structure.
