Disclosed are a pollutant capturer and mobilizer and method of mobilizing a polluted gaseous substance from one location towards another location and capturing one or multiple types of polluting substances, such as CO.sub.2, from an atmospheric body of polluted gaseous substance or from exhaust of vehicles, chimneys, or stacks and thereby combat the negative health, environmental, and economic impacts of the of the polluting substances on communities. Wet or dry embodiments of the pollutant capturer and mobilizer utilize wet or dry pollutant capturing components, respectively, to capture one or multiple types of polluting substances from a body of polluted gaseous substance. Flow establishing devices can be used to set the body of polluted gaseous substance in motion through the pollutant capturing component. The pollutant capturer and mobilizer may also be mounted on any type of vehicles, with or without using flow establishing devices.

A seed planter for creating and planting together the combination of both seed and contents of a seed growing environment. The seed planter includes, for example, a wheeled frame configured with at least one soil opener and at least one soil closer for planting a field. A seed growing environment aggregator assembly has at least one input opening for receiving a plantable portion of a seed growth medium and seed from the seed hopper and at least one discharge opening for discharging an aggregation of the plantable portion of the seed growth medium and seed to the at least one soil opener for planting a desired growing environment in the field.

A vertical growing system includes a frame assembly extending above a base surface, the frame assembly includes a support grid defining a longitudinal axis. The system further includes a propagation tray having a chamber for holding a plant therein and a mounting tray. The mounting tray is removably attached to the frame assembly and includes an interior surface sized to receive at least a portion of the propagation tray therein. The system further includes a positioning member sized to extend from the interior surface of the mounting tray to the propagation tray when the propagation tray is received within the mounting tray. The positioning member is shaped to orient the chamber at a first oblique angle relative to the longitudinal axis of the support grid.

Crops, for example microgreens, may be aeroponically grown from seed on substrates. The substrates may be seeded with the substrates in a horizontal position, and then arranged vertically for germination and further growth. A gelling material in solution, with the gelling material for example a gellum, may be applied to the substrates, while in the horizontal position, so that the seeds are retained on the substrates when the substrates are moved to a vertical position.

An agricultural row cleaner having: a frame; a first row cleaner wheel disposed on a first side of the frame; a second row cleaner wheel disposed on a second side of the frame; and a row cleaner diverter connected to the frame and disposed forward of the first row cleaner wheel and the second row cleaner wheel in a direction of travel and disposed between the first row cleaner wheel and the second row cleaner wheel.

A seed coulter arranged to place one or more inputs in a groove behind a tine of a direct seed drill for field crops. The seed coulter is arranged for displaceable connection to the tine and is freely displaceable in the longitudinal direction of the tine between a lower position and an upper position. A seeding unit comprising the seed coulter, and a direct seed drill comprising a plurality of seeding units are described as well.

A system for capturing CO.sub.2 from gases, a pre-cooled stream of the gases is conducted through a bed of CO.sub.2 adsorbent in a first direction capturing CO.sub.2 from the gases in the CO.sub.2 adsorbent bed, a stream of warm heating gas is conducted from a heat storage unit to said CO.sub.2 adsorbent bed in a second direction opposite the first direction transferring stored heat from the heat recovery unit to the adsorbent bed, while simultaneously transferring coldness from the adsorbent bed to the heat storage, the heating gas is conducted through the adsorbent bed in a closed loop desorbing CO.sub.2 from the adsorbent bed, the desorbed CO.sub.2 is extracted a stream of cooling gas is conducted through the heat storage unit and the CO.sub.2 adsorbent bed in the first direction transferring low-temperature heat to the adsorbent bed and high-temperature heat from the adsorption bed to the heat storage unit.

An agricultural implement includes at least one row unit having a plurality of support members, each of which is pivotably coupled to an attachment frame or another of the support members to permit vertical pivoting vertical movement of the support members, and a plurality of soil-engaging tools, each of which is coupled to at least one of the support members. A plurality of hydraulic cylinders are coupled to the support members for urging the support members downwardly toward the soil. A plurality of controllable pressure control valves are coupled to the hydraulic cylinders for controlling the pressure of hydraulic fluid supplied to the cylinders. A plurality of sensors produce electrical signals corresponding to predetermined conditions, and a controller is coupled to the sensor and the controllable pressure control valves. The controller receives the electrical signals from the sensors and produces control signals for controlling the pressure control valves.

A mobile agricultural machine includes a row unit having a furrow opener mounted to the row unit and configured to engage a surface of ground over which the mobile agricultural machine travels to open a furrow in the ground. A furrow closer is mounted to the row unit behind the furrow opener and configured to engage the surface of the ground to close the furrow. A furrow sensor system is mounted to the row unit and configured to sense characteristics relative to the furrow opened by the furrow opener and generate a sensor signal indicative of the characteristics. The mobile agricultural machine can further include a control system configured to determine a furrow quality metric corresponding to the furrow sensed by the furrow sensor system based on the sensor signal and generate an action signal to control an action of the mobile agricultural machine based on the furrow quality metric.
