Abstract

Abstract An air cleansing system for cities and other geographically located areas in which geothermal wells supply heat to a top surface of a body of water upwind from the geographical area, creating a moist high pressure area over the water. The high pressure area, moved by the wind will precipitate the smog particles from the air.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 351 words
A system for movement of smog laden air from over a populated geographical area having a cooler, temperature inversion layer disposed over the smog laden air, said system comprising: an open basin containing a body of water located within the line of flow of prevailing winds toward said area, said basin having an upper surface exposed to the air and a lower surface adjacent the ground; at least one geothermal well located within and below said basin including a casing having an upper portion extending through said body of water, a lower portion extending downwardly into a sub-surface, geothermal zone having a temperature of at least 500*F, a plug inserted into the bottom end of the casing and a cap closing the upper portion of the casing; a closed heat exchanger forming the lower portion of the casing, being disposed within said zone and having an inlet and an outlet; a water inlet penetrating the upper portion of said casing within said body of water having one end communicating with said body of water in the vicinity of the lower surface of the basin and a second end connected to the inlet to the heat exchanger; a heated water outlet penetrating said casing within said upper portion having a discharge end connected to said body of water in the vicinity of the upper surface of the basin and a second end connected to the outlet to said heat exchanger; pump means connected to said water inlet and to said heated water outlet for delivering cooler water from the bottom of the basin to the heat exchanger and for discharing a sufficient amount of heated water on the top of the basin to form a body of moist, warm, high pressure air over said body of water which rises into said prevailing wind and said body of moist air when moved by the prevailing winds will mix with said smog laden air and will cause rise of said cooler inversion layer over said geographical area and will result in movement of said smogmoist air mixture with said wind away from said area.
Claim 2
Independent Claim 351 words
A system for movement of smog laden air from over a populated geographical area having a cooler, temperature inversion layer disposed over the smog laden air, said system comprising: an open basin containing a body of water located within the line of flow of prevailing winds toward said area, said basin having an upper surface exposed to the air and a lower surface adjacent the ground; at least one geothermal well located within and below said basin including a casing having an upper portion extending through said body of water, a lower portion extending downwardly into a sub-surface, geothermal zone having a temperature of at least 500*F, a plug inserted into the bottom end of the casing and a cap closing the upper portion of the casing; a closed heat exchanger forming the lower portion of the casing, being disposed within said zone and having an inlet and an outlet; a water inlet penetrating the upper portion of said casing within said body of water having one end communicating with said body of water in the vicinity of the lower surface of the basin and a second end connected to the inlet to the heat exchanger; a heated water outlet penetrating said casing within said upper portion having a discharge end connected to said body of water in the vicinity of the upper surface of the basin and a second end connected to the outlet to said heat exchanger; pump means connected to said water inlet and to said heated water outlet for delivering cooler water from the bottom of the basin to the heat exchanger and for discharing a sufficient amount of heated water on the top of the basin to form a body of moist, warm, high pressure air over said body of water which rises into said prevailing wind and said body of moist air when moved by the prevailing winds will mix with said smog laden air and will cause rise of said cooler inversion layer over said geographical area and will result in movement of said smogmoist air mixture with said wind away from said area.
Claim 3
Dependent Claim 23 words
A system according to claim 1 wherein geothermal well includes a concrete layer surrounding the exterior of the casing and in engagement therewith.
Claim 4
Dependent Claim 25 words
A system according to claim 1 wherein said pumping means includes valve means for controlling the flow of inlet water and outlet discharge heated water.
Claim 5
Independent Claim 182 words
A method of moving smog laden air from over a populated geographical area having a cooler, temperature inversion layer disposed over the smog laden air: inserting at least one well casing through an open body of water located within the line of flow of prevailing winds toward said area, said casing extending into a geothermal zone having a temperature of at least 500*F; forming a heat exchanger having a closed end within the portion of the casing disposed within said zone; pumping cooler feed water from near the bottom of the body of water into the heat exchanger and forming heated water therein; pumping heated water from the heat exchanger and discharging a sufficient amount of the heated water near the surface of the body of water to form a body of moist, warm air over the body of water which rises into said prevailing winds, is carried by said winds to said area, mixes with said smog laden air, causes said inversion layer to rise and results in movement of said smog-moist air mixture with said winds away from said area.
Claim 6
Independent Claim 182 words
A method of moving smog laden air from over a populated geographical area having a cooler, temperature inversion layer disposed over the smog laden air: inserting at least one well casing through an open body of water located within the line of flow of prevailing winds toward said area, said casing extending into a geothermal zone having a temperature of at least 500*F; forming a heat exchanger having a closed end within the portion of the casing disposed within said zone; pumping cooler feed water from near the bottom of the body of water into the heat exchanger and forming heated water therein; pumping heated water from the heat exchanger and discharging a sufficient amount of the heated water near the surface of the body of water to form a body of moist, warm air over the body of water which rises into said prevailing winds, is carried by said winds to said area, mixes with said smog laden air, causes said inversion layer to rise and results in movement of said smog-moist air mixture with said winds away from said area.
Claim 7
Dependent Claim 18 words
A method according to claim 4 in which the geothermal zone has a temeprature from 500*F to l,000*F.
Claim 8
Dependent Claim 22 words
A method according to claim 5 in which the well casing is formed of metal and is surrounded by a concrete layer.
Claim 9
Dependent Claim 24 words
A method according to claim 6 further including the step of controlling the flow of said cooler feed water and said heated discharge water.
