Fluid turbines
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.
