Abstract:
A system for purifying water from a water source while conserving energy, natural resources, and area of ground used, the system comprising:an elongated inclined cylinder extending from the water source to an elevated level for transporting water from the water source to the elevated level;a rotatable auger disposed in the cylinder for drawing the water into the cylinder and raising the water through the cylinder to the elevated level;inlet and outlet passages formed in the cylinder, said inlet passage including a series of increasingly fine membranes associated with the cylinder for filtering the water as it passes through the inlet passage to remove debris and contaminates;a vertical shaft coupled to the outlet passage and extending downwardly from the elevated level and including purifying means to purify the water in response to downward movement under force of gravity, a width of the vertical shaft being substantially smaller than a height of the shaft to minimize the area of ground used;a water turbine disposed at a bottom of the shaft for recapturing some of the energy of the descending purified water to assist in rotating the auger;a wind turbine disposed on the vertical shaft positioned above the purifying means and the water turbine;a solar panel disposed on the inclined cylinder;a wave driven device disposed under the inclined cylinder, thereby minimizing the area of ground used; anda power source coupled to the auger for rotating the auger in response to energy from said wind turbine, said solar panel, and said wave driven device.
