Abstract: The concepts relate to reducing energy loss associated with hot water systems. One example is manifest as a system with an automatic hot water recovery apparatus and selective hot water isolation devices. In one example a selective hot water isolation device is configured to be connected in fluid flowing relation with a first water line and a second water line and the selective hot water isolation device is configured to control water cross-over from the second water line into the first water line based upon water flow through the first water line.

Abstract: The concepts relate to reducing energy loss associated with hot water systems. One example can monitor hot water use in a system. Upon completion of the hot water use, the example can recover some of the hot water from hot water lines into a water heater that heated the hot water. The method can also deliver the recovered hot water to the water heater in a manner that affects operation of a heating element of the water heater.

Abstract: The present application relates to selective harvesting of agricultural objects, such as asparagus spears. One described example relates to a harvester that includes at least one set of independently controllable cutter arm assemblies that rotate about a common axis to harvest individual asparagus spears.

Abstract: The concepts relate to reducing energy loss associated with hot water systems. One example includes a water flow management device that includes inner and outer nested elastomeric bladders. The inner and outer nested elastomeric bladders define a tortuous fluid pathway into the inner bladder, between the inner and outer bladders, and out of the outer bladder.

Abstract: The concepts relate to reducing energy loss associated with hot water systems. One example includes a cold water line and a hot water line and an end use fixture in fluid flowing relation with the cold and hot water lines and configured to control water flow therefrom. This example also includes a water heater having an intake or inlet in fluid flowing relation to the cold water line and an outlet in fluid flowing relation to the hot water line. The example includes an automatic hot water recovery apparatus positioned in fluid flowing relation to the cold water line proximate to the water heater, the automatic hot water recovery apparatus configured to draw hot water back into the water heater from the hot water line subsequent to hot water usage at the end use fixture.
