Patent number: 11864539Abstract: An aquaculture system can include stacked growth trays. Animals, such as shrimp, can be transferred between the growth trays for different stages of growth. Waste water can be removed from the growth trays and can be processed by a water treatment system. Treated water can be returned to the growth trays. A valve in a first configuration can permit water to circulate through the growth tray, while impeding the animals from exiting the growth tray. In a second configuration, the valve can permit the animals to exit the growth tray, such as for transition to a subsequent growth tray. A sweeper system can be used for cleaning and/or mixing the water in the growth tray, and/or for pushing the animals out of the growth tray during a transition.Type: GrantFiled: July 8, 2020Date of Patent: January 9, 2024Assignee: Grand Shrimp, LLCInventors: Johan Perslow, Andrew Komor, Michael Morrow

Publication number: 20230323691Abstract: A wave generating system can include a water channel for creating a flow of water to produce a standing wave. A water return passageway can circulate the water back to the inlet of the water channel. One or more pipes can extend under the water channel for circulating the water. A water storage chamber can be positioned below the water channel. Water can be stored in the space between the one or more pipes, and the storage water can be isolated from the water being circulated in the system. The system can produce a hydraulic circuit with hydraulic continuity so that water can be efficiently circulated through the water channel and water return passageway. The system can be modular.Type: ApplicationFiled: March 21, 2023Publication date: October 12, 2023Inventor: Johan Perslow

Publication number: 20080210220Abstract: A solar energy system including a plurality of solar panels mounted at an angle on a flotation device floating on a body of water is provided. A mechanism rotates the flotation device to substantially track the sun as it traverses the sky. The rotation of the flotation device and angled solar panels increases the proportion of incident sunlight that impacts the panels in an approximately perpendicular direction, allowing the sunlight to be absorbed by the panels and converted to electrical energy. The system also stores the energy collected during the day for later use.Type: ApplicationFiled: December 31, 2007Publication date: September 4, 2008Inventor: Johan A. Perslow

Patent number: 6379545Abstract: A modular system for treating wastewater is designed having different phases. In an initial phase, plural tanks are provided, including at least one reactor and digester tank. In a subsequent phase, at least one of the tanks is converted into a different type of tank, and additional new tanks are provided to accommodate larger quantities of wastewater. In one embodiment, conversion of at least one of the tanks is accomplished by removing a temporary wall from a digester tank to create another reactor tank.Type: GrantFiled: August 24, 2000Date of Patent: April 30, 2002Assignee: Pacific Advanced Civil Engineering, Inc.Inventors: Johan A. Perslow, Mark E. Krebs, James A. Matthews

Patent number: 5255999Abstract: A water-level control device is provided for controlling water levels between a high-tide level and a low-tide level. The water-level control device comprises a tiltable pipe connected to a drain pipe by a flexible joint. Tilting of the pipe allows flow of water from a high-tide point to a low-tide point. Water is pumped into a pond continuously, and the variable-height weir cyclically varies the outflow to simulate a tidal cycle.Type: GrantFiled: September 20, 1991Date of Patent: October 26, 1993Assignee: Space Biospheres VenturesInventor: Johan A.

Patent number: 5186578Abstract: Waves are generated on the surface of a body of water, at regular intervals, by a wave generator in which water is periodically lifted and allowed to fall in a water-lift chamber. Water enters and leaves the lift chamber through an underwater opening at its bottom. It is lifted by drawing a vacuum in the top of the lift chamber and dropped by releasing that vacuum. Air is periodically exhausted from the lift chamber to create a vacuum therein by an air blower through an air buffer having a series of interconnected air chambers, to minimize air-pressure fluctuations at the air blower intake. Vacuum in the lift chamber is periodically released by opening it to the atmosphere.Type: GrantFiled: September 20, 1991Date of Patent: February 16, 1993Assignee: Space Biospheres VentureInventor: Johan A.
