Abstract: A separable buoy includes a center float having a top surface that includes an upper peripheral end and an engagement bevel provided on the upper peripheral end that extends below the top surface; a separable float unit detachably disposed at the center float and including a dome wall that is provided in a lower central portion thereof and that has a peripheral edge configured to detachably engage the engagement bevel: and a chamber defined between the dome wall of the separable float unit and the top surface of the center float when the separable float unit engages the center float, wherein the center float has a vertical height that substantially equals or exceeds that of a lower portion of the separable float unit.

Abstract: A wave energy isolation device includes a fixed displacement hydraulic motor and a variable displacement hydraulic pump. The variable displacement hydraulic pump outputs a working fluid to the fixed displacement hydraulic motor. The variable displacement hydraulic pump changes an output displacement of the working fluid according to a control parameter.

Abstract: A separable buoy includes a center float, a separable float unit that is detachably furnished in the center float and a chamber which is connected between the center float and the separable float unit.

Abstract: An energy saving apparatus includes at least a planting rack having at least a panel and a collecting part, a wind pipe, an air conditioner, and an air blower. The panel further has a flow path, and the collecting part is located at a bottom of the panel communicative with the flow path. The wind pipe with bottom nozzles is located above the panel. The air conditioner coupled to the wind pipe is to spray a cool air to the panel through the nozzles. The air blower coupled between the collecting part and the air conditioner is to extract air, so that the cool air can flow from the top to the bottom of the panel, then flow down along the flow path to the collecting part, and finally be supplied back to the air blower for further recycling the cool air to the air conditioner.

Abstract: An energy capturing system includes a first chamber, a second chamber, a spacer element, a pressurization device, an energy capturing device and a pressure stabilizing device. The first chamber and the second chamber are adapted to contain a liquid. The spacer element is located between the first chamber and the second chamber. The second chamber is connected with the first chamber via an opening of the spacer element. Two ends of the pressurization device are connected with the first chamber and the second chamber, respectively. The energy capturing device is located on the opening. The pressure stabilizing device is connected with the first chamber.
