Abstract: This invention relates to a vortex station and method for producing a vortex similar to one of a group consisting of dust-devils and waterspouts. The apparatus comprises a ground platform forming a base for the vortex station, a plurality of vanes to direct an air flow into a vortex station and about the vortex station in a substantially swirling manner, at least one wind turbine disposed near the centre of said vortex station, in a path of a concentrated air flow, wherein the movement of the air in the vortex station is such that an atmospheric buoyancy vortex is created in the centre of the vortex station, a supply of a working fluid (e.g. water) to the vortex station at or near the centre of the vortex station such that the air is of a saturated condition or an at least partially saturated condition with the working fluid (e.g. water), the working fluid (e.g. water) supplied at a sufficient quantity or amount so as to assist with maintaining buoyancy and stability of a vortex created.

Abstract: A link generation system, including a content discovery module for processing data files of a network server to identify servable data, and a link generator for generating links to the servable data to allow the servable content to be accessed using the links. The link generator generates encoded links for accessing dynamically generated data of the network server, the encoded links being in a form suitable for an indexing agent. The link generator processes a database of the network server to determine query data for retrieving servable data from the database. A proxy server receives a request generated in response to selecting one of the encoded links, translates the request, and forwards it to the network server to access corresponding dynamically generated data. The link generation system generates links that can be used to access all of a web site's content, in particular content for which no accessible link previously existed, including dynamically generated content.
