1. A turbine comprising:
a center hub forming a central axis;
a first cylinder operably connected to the center hub and adapted to rotate about the center hub, wherein the first cylinder comprises a first plurality of blades wherein each of the first plurality of blades extends from a top of the first cylinder to a bottom of the first cylinder, wherein the first cylinder comprises a plurality of first support rings;
a second cylinder surrounding the first cylinder, wherein the second cylinder comprises a second plurality of blades wherein each of the second plurality of blades extends from a top of the second cylinder to the bottom of the second cylinder;
wherein each of the first plurality of blades have a curvature that is in a direction different from curvature of the second plurality of blades; and
