Various implementations of a system that addresses the need for clean drinking water, improved solid fuel combustion and convection of the heat resulting from the combustion, exhausting of gases and air-borne particulates resulting from combustion, and provides electricity for lighting and charging of battery-operated devices are described herein. The system may include at least one solar panel, a battery, a fan assisted exhaust hood, a fan assisted cooking device, and a water purification device. Such a device could not only save millions of lives, but the quality of life for millions of people living in impoverished areas or refugee camps could be improved dramatically.

An ocean wave actuated gravitational desalination apparatus and system for generating potable water comprised of, a box platform with a piston pump at sea level, an inverted prism shaped subterranean water tank below sea level, and a desalination processing structure above sea level. When the ocean waves pass over the top of the box platform, the piston pump is raised to open a set of valves to let the sea water into a cylindrical chamber. When the piston goes down, the valves close and a second set of valves open to release the water into the subterranean tank to be further released into containers on a carousal structure that move on rails by gravity. The water in the containers is emptied into holding and pre-filtration tanks and forced through filters into a pipe by the actions of a hydraulic oil pump and the filtered water released for storage and use.

An apparatus for the treatment of drinking water contained in a vessel is disclosed. The apparatus comprises a housing, a drinking water inlet and a drinking water outlet. The apparatus also includes a pump operable to pump drinking water from the water inlet to the water outlet, wherein the water outlet and pump are configured to dispense drinking water generally upwards from the water outlet below a surface of the drinking water to cause a continuing disturbance in a surface of the drinking water contained in the vessel. In one example, the apparatus is used to reduce algae in the water. In another example, the apparatus is used to increase the oxygen content in the water.

The present disclosure provides a system for extracting potable water from saline water. The system includes a pre-treatment unit configured to receive the saline water from a reservoir, and configured to heat the saline water to a predetermined temperature. An evaporator is coupled to the pre-treatment unit for receiving the heated saline water, and includes a housing for receiving the heated saline water, a porous material disposed in the housing and an evaporator gas port. The evaporator gas port routes gas into the housing via the porous material, and disperses to form gas bubbles. The gas bubbles induce turbulent motion within the housing for converting the heated saline water into the mixture of the water vapors and the concentrated saline water. Further, a condenser is coupled to the housing for receiving the mixture of the gas and the water vapors, and configured to condense water vapors to form potable water.

A portable water filtration system that is configured to provide potable water from a contaminated water source. The portable water filtration system includes a pre-treatment module and a polishing module that are fluidly coupled and contained within a stackable housing configuration. The pre-treatment module has disposed therein a pump, two solenoid valves, a first filter and a pair of ultra-filters wherein the aforementioned elements are all fluidly coupled utilizing plastic tubing. Water is cycled through the elements of the pre-treatment module and is then directed to the polishing module. Disposed within the polishing module are four filters that have filtration material therein operable to filter material within a range of 0.0002 to 0.0009 microns. The portable water filtration system is operable in a filtration mode and a flush mode.

The present invention relates to a water-purifying lid having a self-powered UV LED and a filter coupled thereto, the lid comprising: a first body having a box shape and open at one end thereof; a support plate installed in an inner space of the first body to form a space; a rotational part; a coil part; a handle coupled to one end of a rotational shaft at one end thereof so as to rotate the rotational shaft when a force is applied thereto; an ultraviolet sterilization device; a second body; a filter for removing impurities; and a discharge part comprising a valve, wherein a user rotates the rotational shaft and a rotational plate by using the handle, a magnet moves above the coil part with the rotation of the rotational plate to generate electricity at the coil part, and the electricity having been generated at the coil part is transferred to a UV LED of the sterilization device, thereby emitting an ultraviolet ray which sterilizes water in the second body.

A solar desalinator that converts contaminated water to potable water includes a cylindrical solar collector, a trough-shaped parabolic mirror, and a condenser. The solar collector is positioned within the trough-shaped parabolic mirror, and the parabolic mirror focuses the Sun's rays onto the solar collector, heats the water, and converts the water to steam. The steam is fed to the condenser where the steam is condensed to recover potable water. The solar collector includes an inner conduit surrounded by an outer shell with a vacuum in the anger space between. Energy absorbing material in the form of dark metal is positioned in the inner conduit. A residue bulb is attached at the contaminated water inlet to collect residue left by the creation of the steam.
