Abstract: An aging apparatus including a pulse laser, a beam expansion assembly, and a platform configured to carry an object is provided. The pulse laser transmits a first beam to the beam expansion assembly. The beam expansion assembly expands the first beam to a second beam and projects the second beam onto the object.

Abstract: A floating apparatus and method for cleaning water in a pool or tank are provided. The floating apparatus includes: a body having at least one discharge outlet; an electrical power source having a solar power collector that is mounted on a top portion of the body, wherein the body has a contour wall for allowing the solar power collector to face up; an ozone generator connected to the electrical power source; an ozone conduit in gas communication with the ozone generator and the at least one discharge outlet; and a transparent cover covering the solar power collector, whereby ozone produced in the ozone generator is discharged from the discharge outlet and provides the power for moving the floating apparatus.

Abstract: A system for producing supercritical ozone includes a reactor having a first connecting port and a second connecting port, an ozone generator connected to the first connecting port, a fluid-driving device connected to the ozone generator and the second connecting port, and a fluid source connected to the reactor. The fluid-driving device is configured to circulate the gas in the reactor through the ozone generator. The fluid source is configured to increase the pressure in the reactor and thereby produce supercritical ozone.
