A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex. The lagoon includes a surf feature and surrounding the lagoon are entertainment, educational, sports, and commercial facilities. The complex has a controlled public access and provides the look and feel of a tropical beach with clear waters and sandy beaches. In addition a method for efficiently utilizing facilities and land that are vacant, underutilized, have limited uses, or that are contiguous to or nearby recreational, educational, sports, or commercial venues is disclosed. The method providing a publicly accessible urban beach entertainment complex with a centerpiece man-made tropical-style pristine-clear lagoon having a surf feature. The method allows for generating revenue and increasing efficiency by pairing vacant sites, underutilized sites, limited use land, or sites that are contiguous to entertainment, educational, sports, and/or commercial venues with urban beach entertainment complexes. The complex preferably has a controlled public access, thereby allowing entrance upon payment of a fee.

A hydrodynamic heater includes an inlet port for receiving a stream of fluid from an external source and an outlet port for discharging a stream of heated fluid from the hydrodynamic heater. A hydrodynamic chamber operates to selectively heat fluid present within an interior region of the hydrodynamic chamber. The hydrodynamic chamber includes an inlet port and an outlet port located along an interior wall of the hydrodynamic chamber. The hydrodynamic chamber inlet port is fluidly connected to the inlet port of the hydrodynamic heater. The hydrodynamic heater includes a fluid metering device having an inlet fluidly connected to the hydrodynamic heater inlet port and an outlet fluidly connected to the inlet port of the hydrodynamic chamber.

A cavitation boiler segment includes a rotor to be coupled with a rotating inner drum and a stator surrounding the rotor segment. The rotor and the stator each include drums with two banks of annular apertures, which overlap to define two cavitation regions. The rotor includes a web bifurcating the rotor between the apertures into an upstream side and a downstream side, each forming a separate fluid passage between a face of the rotor and a bank of apertures. The stator includes a casing enclosing the stator apertures in a fluid passageway. In operation, fluid flows into a first side of the rotor, across a first cavitation region and into the stator, then back across the second cavitation region and into the second side of the rotor where the fluid may flow into a first side of an adjacent segment.

An experimentation apparatus tests for heat produced by cavitation. The experimentation apparatus includes a heating chamber, a quantity of heavy water, a piezo-disk antenna, a target foil, a transmission line, a signal generator, a control unit, and at least one sensor. The heavy water is retained within the heating chamber and is agitated by the piezo-disk antenna to form cavitation bubbles. These cavitation bubbles impact the target foil in order to potentially produce deuteron combination events that could consequently produce heat. The signal generator sends an electrical signal along a transmission line to the piezo-disk antenna in order to dictate how the piezo-disk antenna vibrates within the heavy water. The control unit is used to manage the operational functionalities of the experimentation apparatus such as instructing the signal generator to adjust the frequency of the electrical signal. The at least one sensor collects experimentation data within the heating chamber.

The present invention discloses an air energy boiler and belongs to the technical field of energy conversion. A crankshaft of the boiler is fixed at the output end of a rotating unit. The crankshaft is provided with at least one bulge. A driving piston of each conversion assembly is arranged in an air cavity in a reciprocating motion. The driving piston divides the air cavity into a first cavity and a second cavity. A wrist pin is arranged in the second cavity, and the wrist pin is fixed and connected with the driving piston. Both ends of a piston rod is rotatably connected with the wrist pin and the corresponding bulge respectively. The first cavity is provided with an air intake. Multiple heating pipes are in communication with the first cavity at one end and stretch into the boiler body at the other end. The boiler body is sealed and stores water, and the boiler body is provided with a steam outlet, wherein the steam outlet of the boiler body is connected to various terminals through the use of pipelines. Since air is used as the heat source, no conditional limitations exist for installation, and it is safe to use and saves energy and electricity.
