Benefits of technology
[0015] Alternatively, chutes able to contain a significant quantity of water may be combined with some forms of smaller wave generators, where such wave generator could generate a wave directly within the chute. For example, a recessed wave generating pneumatic discharge tube, as described further below, could generate a wave in a chute while not interfering with the sliding activities of a rider.
Problems solved by technology
Because of the effect of friction and loss of energy caused by changing different directions (i.e., acceleration) away from a simple fall, serpentine slides may be limited to slower speeds.
In addition, in some cases the water flow may not be adequate throughout the slide for the individual to remain at speed.
Traditional waterslides lacked the means for imparting additional energy to the individual once they entered the slide—the course of the slide was traveled by expending potential energy.
Elevations were small and limited because each incline consumed energy and reduced speed.
Water jets involve localized energy transfers solutions that risk causing some discomfort for the rider.
Further, the imparting of additional energy extends the duration of a water slide.
Of course, this approach relies on placing structure within the area of activity in the channel, limiting its usefulness for certain activities.
A rider falling into a channel with flowing water might strike the structure or the tethering apparatus.
Thus, each of these features is limited in the means of propulsion, which is usually by the force of gravity (i.e., on both the individual and the water), or by the force of supplemental pressurized water gushes or jets.

Embodiment Construction
[0026] Preferably the wave generator used in the present invention will not interfere with the chute, will be scalable to various sizes or applications, will be remotely controllable, and will be capable of generating ridable waves. Embodiments of the present invention may include one or more pneumatic wave cannons for the generation of waves, as may be desired for the application. Ocean surface waves are primarily created by winds that cause variations in surface pressure. Wind duration, strength, and surface coverage area contribute to the resulting wave. A wave cannon is a wave generating device as disclosed in U.S. Pat. No. 5,833,393 to Carnahan et al., which is hereby incorporated by reference. In short, the wave cannon transfers energy from the escape of compressed air to water to create swells or waves. When used in conjunction with appropriate hydrodynamic bottom contour, the wave can be rendered ridable or breaking. Other devices for the generation of ridable waves may serv...

An alternative propulsion or motive force for the riders of water features based on generated waves. A wave generator may be used to propel individuals or vessels within a chute for recreation or transportation. In one form, a pool or container having a body of water is configured to support an artificial wave generator. Portions of the waves generated in a pool may be captured in a variety of ways by chutes for stand-alone rides or for portions of chutes in water slides. Alternatively, a wave generator may generate a wave directly within a chute so long as the chute provides sufficient water and proper hydrodynamic characteristics to support a ridable wave.
Description
CROSS REFERENCE TO RELATED APPLICATIONS [0001] The present application claims priority from U.S. Provisional Application Ser. No. 60 / 632,278, filed Dec. 1, 2004.FIELD OF THE INVENTION [0002] The present invention relates to water rides or activities. More particularly, the present invention is a recreational water feature incorporating artificially generated waves or swells as a means of propulsion for riders. BACKGROUND OF THE INVENTION [0003] Millions of individuals visit water parks every year to enjoy, among other attractions, various types of water slides, flumes, etc. In particular, water slides are generally known in the field as providing recreation involving water based motion or rides. [0004] One common and simple category of water slides involves a sloping chute by which gravity draws a stream of water down the slide. The chute is typically manufactured from fiberglass full or half round segments that are fastened together. Water is pumped to the high point and then relea...
