Abstract: A reciprocating aquaponic device includes a housing, a bell-shaped siphon, and a water pump. The housing defines a water inlet space, and a tidal space and a planting space in fluid communication with the water inlet space. The housing includes a mounting wall over the tidal space, and an inclined wall under the tidal space. The inclined wall is inclined downward toward the planting space. The bell-shaped siphon is dispose on the mounting wall and is disposed for moving water from the water inlet space through the siphon opening and into the tidal space. The water pump is disposed in the fish tank for drawing water from the fish tank into the water inlet space.

Abstract: A system for producing biomass vinegar and charcoal includes a furnace, which has an outer shell defining a lower combustion chamber and an upper heating chamber, and an inner tank removably received in the heating chamber. A cooling pond has a cooling region to accommodate the inner tank. A condenser in a collection barrel condenses smoke gases from the inner tank to produce biomass vinegar. A first temperature sensing pipeline removably connects the inner tank, After the biomass is carbonized, the first temperature sensing pipeline is removed from the inner tank, and the inner tank is moved to the cooling region to be cooled by a sprinkler.

Abstract: A water purification tumbler includes a main body and a filtration unit. The filtration unit includes an annular wall, a flow conducting member, a high-temperature bamboo charcoal layer, and a low-temperature bamboo charcoal layer. The flow conducting member is disposed inside of the annular wall and defines a flow channel communicating with an opening of the main body. The flow channel has a water inlet section and a water outlet section. The water inlet section gradually narrows downward. The high-temperature bamboo charcoal layer and low-temperature bamboo charcoal layer are connected to the flow conducting member and are disposed respectively above and under the flow channel.
