Abstract: A bladeless fluid/vapor includes: (a) three or more turbine discs disposed within a case, wherein each turbine disc has a center opening, a first set of holes substantially equally spaced from one another along a first radius, a second set of holes substantially equally spaced from one another along a second radius, and two or more of the turbine discs have a set of exhaust ports positioned annularly around the center opening; (b) the case includes a main housing, a cover and one or more fluid/vapor inlets oriented to direct a fluid/vapor onto an outer portion of the turbine discs; (c) a drive shaft passing through the center openings of the turbine discs and attached to the turbine discs; (d) a fluid/vapor outlet in the cover; and (e) a set of exhaust holes proximate to and connected to the fluid/vapor outlet that are positioned annularly around the drive shaft.

Abstract: The bladeless turbine includes a case, three or more turbine discs disposed within the case. Each turbine disc has a center opening, and two or more of the turbine discs have a set of exhaust ports positioned annularly around the center opening. A drive shaft passes through the center openings of the turbine discs and is attached to the three or more turbine discs, wherein the drive shaft is positioned within the case along the centerline, free to rotate within the case, and extends through the case for connection to a generator. The one or more fluid/vapor inlets are attached to the main housing such that a fluid/vapor is directed at a specified angle onto the three or more turbine discs. The fluid/vapor outlet is aligned with the centerline. A set of exhaust holes proximate to and connected to the fluid/vapor outlet that are positioned annularly around the drive shaft.

Abstract: A solar energy power generation system generates AC electrical power from solar radiation through the use of parabolic troughs to capture the energy and a fluid turbine to convert the solar energy to mechanical energy. The turbine is directly coupled to a generator to produce AC electrical power.
