Abstract
Airpowered water displays for generating transient water displays which may have variable and high energy content are disclosed. In one form, a cylindrical chamber with a nozzle at one end thereof is disposed within a pool or lake so that the tip of the nozzle is substantially flush with the top of the water. Coupled to the lower part of the cylindrical chamber through a solenoid valve is a compressed air tank which, between firings, is filled with compressed air at a pressure selected in accordance with the height of the water display desired, with the pressure being varied between firings, such as by way of computer control. Opening of the solenoid valve couples the high pressure air to the bottom of the water column in the cylindrical chamber, forcing most of the water therein upward through the nozzle to heights which may reach one hundred fifty feet or more, dependent upon the pressure. Between firings, the cylindrical chamber is automatically refilled by the surrounding water. Various embodiments, including a lighted embodiment are disclosed.
