Method and apparatus for enhancing the pumping action of a geyser pumped tube
This patent describes a geyser pump system comprising: a riser tube having upper and lower ends; means for heating the riser tube; a liquid medium column filling the tube to near the upper end; bubble generating means in the riser tube below the liquid level near the upper end for generating vapor bubbles when the riser tube is heated; the bubble generating means comprising a cavity to isolate a volume of the liquid medium; the cavity having at least one aperature in communication with the bulk of the liquid medium for generating vapor bubbles when the isolated volume of liquid in the cavity is heated. A temperature rise in the isolated volume of liquid causes formation of bubbles at least one aperature.
