Systems and methods for generating electricity from a fluid turbine are provided. In one aspect, the system employs a Tesla turbine to rotate a drive shaft, the drive shaft providing torque to operate an electrical generator. The incoming fluid flow that operates the Tesla turbine enters a hollow portion of the drive shaft and exists the system as an exhaust flow. The system may operate from standard water supplies provided to a residence or business, thereby reclaiming excess water pressure energy.

An energy generating device for generating energy from a flowing fluid, especially from a wind flow and/or from a water flow, comprises: a rotation body, the rotation body extending along an axis of rotation between a first point and a second point and the rotation body being adapted to rotate about the axis of rotation and the rotation body being formed from at least a first, a second, and a third rotation segment, wherein the rotation segments are joined together and arranged along the axis of rotation, and they form a region at least partly surrounded by fluid, wherein the second rotation segment is situated between the first and the third rotation segment and has a different diameter than the first and third rotation segment; and a generator device mechanically connected to the rotation body, wherein the generator device is adapted to generate energy which is produced from the rotation of the rotation body.

A turbine system includes a housing with a fluid inlet, a fluid outlet, and a rotational mount, and a turbine mounted on the rotational mount. The turbine comprises a first disk with a through-hole, a plurality of first foils arranged radially, and a last disk with a smaller through-hole and. The first foils define a fluid path from the fluid inlet to the fluid outlet. The design allows for efficient fluid flow and rotation of the turbine about the axis, providing an effective and reliable turbine system for various applications.

An apparatus for converting rotation into fluid flow and/or fluid flow into rotation. The apparatus comprises a first stage including a coiled fluid conduit having an inlet and an outlet, a first fluid separator configured to receive batches of first fluid and batches of second fluid from the outlet of the coiled fluid conduit of the first stage and separate the first fluid and the second fluid, a second stage including a coiled fluid conduit having an inlet and an outlet, and a first interstage flow channel connecting the first fluid separator with the inlet of the coiled fluid conduit of the second stage for providing first fluid to the inlet of the coiled fluid conduit of the second stage.

An apparatus for converting rotation into fluid flow and/or fluid flow into rotation. The apparatus comprises a coiled fluid conduit having an inlet and an outlet, a support arrangement holding the coiled fluid conduit such that the inlet is higher/lower the outlet, a first fluid separator configured to receive batches of first fluid and batches of second fluid output from the outlet of the coiled fluid conduit and separate the first fluid and the second fluid, and an intrastage flow channel connecting the first fluid separator with the inlet of the coiled fluid conduit to allow second fluid separated by the first fluid separator to be transported back towards the inlet of the coiled fluid conduit.

This invention describes the concept of a new configuration of cross-flow kite power system and its operation method. An analytical model was developed as analysis and design method for the design of the system and, especially, to design the generator turbine to match the kite in order to obtain maximal power.
