A generator is connected by a shaft to the wind turbine for generating electrical power by the rotation of the wind turbine. A method of extracting energy from moving gas comprises rotating a wind turbine having two blades by omnidirectional gas motion. The method includes connecting a generator by a shaft to the wind turbine and generating electrical power by the rotation of the wind turbine. ## Claims ### Claim 1 A wind turbine, comprising: a wind turbine having two blades connected by a shaft extending between an upper and a lower portion of the two blades and being rotated about the shaft by omnidirectional gas motion with vertical and horizontal gas components; the turbine being a generally spherical shell consisting of the two blades, each of which is an identical areal segment comprising half the surface area of the spherical shell and having a blade edge formed of a single two-wavelength sinusoid that extends from the upper portion to the lower portion of the spherical shell and then back to the upper portion on a far side of the shell; and a generator connected by the shaft to the wind turbine for generating electrical power by the rotation of the wind turbine. ### Claim 2 (depends on 1) The wind turbine of claim 1 wherein the two blades are rotated by omnidirectional air motion. ### Claim 3 (depends on 1) The wind turbine of claim 1 wherein the two blades are separated by two exhaust regions in an upper part of the turbine and two inlet regions in a lower part of the turbine. ### Claim 4 (depends on 1) The wind turbine of claim 1 wherein the two blades are joined together by a circular plate mounted to the upper portion of the two blades. ### Claim 5 (depends on 4) The wind turbine of claim 4 wherein the two blades butt together beneath the circular plate. ### Claim 6 (depends on 1) The wind turbine of claim 1 further including: a base assembly housing the generator; a plurality of spaced air inlet ports disposed about a perimeter of a lower portion of the base assembly; and a hollow stack mounted at one end to the base assembly and housing the shaft connecting the generator to the wind turbine. ### Claim 7 (depends on 6) The wind turbine of claim 6 wherein the plurality of spaced air inlet ports are evenly spaced about the perimeter of the lower portion of the base assembly. ### Claim 8 (depends on 1) The wind turbine of claim 1 wherein a butt junction of the blade edges of the two blades forms a dihedral angle W which determines the relative positions of the blades to each other. ### Claim 9 (depends on 8) The wind turbine of claim 8 wherein the dihedral angle is in the range of 10 degrees to 40 degrees. ### Claim 10 (depends on 8) The wind turbine of claim 8 wherein: wind turbine and generator are disposed above a source of rising gas whereby the gas impinges against a lower portion of the wind turbine causing it to rotate the generator by way of the shaft. ### Claim 11 A method of extracting energy from moving gas comprising: providing a wind turbine being a generally spherical shell consisting of the two blades, each of which is an identical areal segment comprising half the surface area of the spherical shell and having a blade edge formed of a single two-wavelength sinusoid that extends from the upper portion to the lower portion of the spherical shell and then back to the upper portion on a far side of the shell; rotating the two blades of the wind turbine about a shaft extending between an upper and a lower portion of the two blades by omnidirectional gas motion with vertical and horizontal gas components; connecting a generator by the shaft to the wind turbine; and generating electrical power by rotating the wind turbine. ### Claim 12 (depends on 11) The method of claim 11 including rotating the two blades by omnidirectional air motion with vertical and horizontal air components. ### Claim 13 (depends on 11) The method of claim 11 including forming a dihedral angle W in the range of 10 degrees to 40 degrees of the blade edges of the two blades which determines the relative positions of the blades to each other. ### Claim 14 (depends on 11) The method of claim 11 including joining the two blades by a circular plate mounted to the upper portion of the two blades. ### Claim 15 (depends on 11) The method of claim 11 including separating the two blades by exhaust regions in an upper part of the turbine and inlet regions in a lower part of the turbine. ### Claim 16 (depends on 15) The method of claim 15 including: housing the generator in a base assembly having a plurality of spaced air inlet ports disposed about the perimeter of the lower portion of the base assembly; mounting a hollow vertical stack at one end to the base assembly; housing the shaft connecting the generator to the wind turbine within the stack; and heating air in the base assembly so that the air rises through the vertical stack to thereby impinge upon the lower portion of the wind turbine causing it to rotate and thus to deliver torque and rotational power to the generator by way of the shaft. ### Claim 17 (depends on 15) The method of claim 15 including: disposing the wind turbine and generator above a source of rising gas; impinging the gas against a lower portion of the wind turbine causing it to rotate the generator by way of the shaft. ### Claim 18 (depends on 17) The method of claim 17 including: directing the rising gas into two inlets in the lower portion of the wind turbine; allowing the rising gas to exit the wind turbine through two exhausts in an upper portion of the turbine causing it to rotate and thus to deliver torque and rotational power to the generator by way of the shaft.
