Abstract: The present invention provides a swirly fluid sprinkler comprising a sprinkling body, a fluid guide, and an electrical generator. The fluid guide disposed inside the fluid inlet of the sprinkling body includes a plurality of swirl channels for dividing a fluid flow into a plurality of swirly fluid flows. The electrical generator disposed inside the sprinkling body and opposite to the fluid guide has a plurality of blades disposed on the top thereof. Each of the blades has an inclining angle wherein the blade surface opposite to the fluid guide has an angle in relation to the corresponding swirly fluid for receiving the propelling force from the swirly fluid so as to rotate the electrical generator and thereby generate electrical power. In another embodiment, the swirly fluid sprinkler further has a lighting module for providing illumination while the water spray is discharged.

Abstract: A wind-tunnel type power generator includes an outer cover, a turbine rotor, an air escape valve, and at least a rear fin. The outer cover is a convergent-divergent shape and the turbine rotor is installed into an inner flowing path thereof, the air escape valve is installed on the outer cover and the rear fin is installed on the surface of the outer cover. The acceleration of the outer cover, the higher efficiency of the turbine rotor, and the reducing pressure of the air escape valve is to gain the wider operation area, smaller space, lower weight, lower noise, and higher efficiency of the wind-tunnel type power generator.
