A sky turbine, having impeller blades with a plurality of panels that can telescope inward and outward. The pitch of the panels can be adjusted, and the pitch of each panel on a blade, passing from the innermost panel to the outermost panel, differs from the pitch of the previous panel by a certain adjustable amount. The sky turbine is preferably mounted above a city at a sufficiently high elevation that air current will be generally faster than just above the ground. In the preferred embodiments, a wing with two pods is pivotally mounted on a tower. Each pod has front and rear shafts, from which four blades extend. Servomotors cause the wing to turn so that its center of symmetry is parallel to the direction the sky is moving, cause the pitch of the panels of the blades to change, and cause the panels of the blades to telescope.

I claim: 1. A sky turbine, comprising: at least one shaft; and blades extending from the at least one shaft, each blade having at least three telescoping panels; wherein pressure of air current against the blades causes rotation of the at least one shaft, which is used to generate electricity; wherein the sky turbine is mounted above a city at the top of a tower containing the city, at a sufficiently high elevation that air current will be generally more rapid than on the ground. 2. A sky turbine, comprising: a plurality of shafts; and blades extending from each of the shafts, each blade having at least three telescoping panels; wherein the angles of the panels of the blades are adjustable; wherein there are two parallel pods, with each pod having two opposite ends containing one of the shafts, with the blades extending radially outward from the one shaft in each end; wherein the pods are retained on a wing that can pivot on a vertical axis; and servomotors cause the wing to turn so that the center of symmetry of the wing is parallel to the direction air is moving, and regulate changes in the speed of rotation of the shafts by causing the angles of the panels of the blades to change and the panels of the blades to move telescopingly, according to the speed of the air current. 3. The sky turbine according to claim 2, wherein when the blades telescope inward, the panels of the blades nearer to the one shaft are nested within the panels of the blades further from the one shaft. 4. The sky turbine according to claim 3, wherein the angles of the panels and the aspect ratio of each blade are adjustable while in operation. 5. The sky turbine according to claim 4, wherein one end of each pod is a front end, and the other end of each pod is a rear end, and the shafts in the front ends of the pods rotate independently of the shafts in the rear ends of the pods. 6. The sky turbine according to claim 5, wherein the shafts and blades on the front ends of the pods counter-rotate and the blades intermesh, and the shafts and blades on the rear ends of the pods counter-rotate and the blades intermesh. 7. The sky turbine according to claim 6, wherein planetary gears increase the speed of the shafts. 8. The sky turbine according to claim 7, wherein each of the panels of each of the blades is a symmetrical airfoil having: a. a chord (C) as its length, b. a width (B), c. a dimension (A) which is, d. a leading edge radius (r), e. a line (M) perpendicular to the chord (C) and located at the dimension (A) from a trailing edge, f. a dimension (X), g. a radius (R) centered on the line (M), h. a straight portion, tangent to the radius (R) and the trailing edge.
