Abstract
The invention generally relates to turbines that efficiently process air or fluid flow while producing substantially no vibrational effects. In certain embodiments, the invention provides a turbine including a rotatable shaft, and at least one blade connected to the rotatable shaft, in which the blade includes a helical shape and an angle of about 180° or greater.
Claims20
A turbine comprising:
- a rotatable shaft;
- and
- at least one blade connected to the rotatable shaft, wherein the blade comprises a helical shape and has an angle of about 180° or greater.
A turbine, the turbine comprising:
- a rotatable shaft;
- and
- a plurality of blades connected to the rotatable shaft, wherein each blade comprises a helical shape and the blades are twisted to such a degree that vibrational effects from rotation of the blades are substantially eliminated.
A wind turbine, the turbine comprising:
- a rotatable shaft;
- and
- a plurality of blades connected to the rotatable shaft, wherein each blade comprises a helical shape and the blades are twisted to such a degree that the blades rotate about the shaft at a speed greater than the actual wind speed.
