Patent ID: 7597559

Claim:
A method for imitating a natural geyser eruption comprising the steps of: providing an apparatus comprising a closed cavity filled with a liquid, a heating device for heating the liquid, a feeding pipeline for the supply of liquid to the cavity, a U-shaped pipe arrangement one branch of which forms a downward-directed descending pipe and another branch of which forms an upward-directed geyser channel, and an additional pipe line with a device for adjusting the depth of immersion of one end of the aforementioned common discharge pipe into the liquid of the cavity while the opposite end of the common discharge pipe exits to the surrounding atmosphere in the form of an eruption pipe and is connected to the aforementioned U-shaped pipe arrangement; heating the liquid in the aforementioned cavity until formation of steam of said liquid; continuing heating the liquid for increase of pressure in the cavity, for mixing the liquid with the steam of said liquid, and for displacing the mixture of liquid and steam of said liquid from the addition pipeline through the U-shaped pipe arrangement to the atmosphere in the form of a natural geyser erupting to the atmosphere through the eruption pipe due to a rapid explosion-like development of pressure in the cavity, the common discharge pipe, and the U-shaped pipe arrangement.
