Abstract: Disclosed are methods and systems for the production of ammonia biologically using a strain of nitrogen fixing bacteria of the Nostocaceae family.

Abstract: Plants are grown in adjacent rows of trays that are rotated within a pool of a nutrient solution. The roots of the plants are at least partly immersed in the nutrient solution. Each row includes a gap wide enough to receive a single tray from an adjacent row. Using three rows, the plants are planted only in one of the rows, and later the rotation is used to space the planted trays one tray apart. Each tray is a parallelepipedal block with apertures for supporting respective plants. The long sides of the blocks have protrusions for preventing adhesion of the blocks. Airlift pumping circulates the nutrient solution past the roots and maintains at least 80% dissolved oxygen saturation in the nutrient solution. A screen of parallel inflatable tubes provides adjustable shade above the pool.

Abstract: Plants are grown by using a nutrient film over a trough of nutrient solution. The film is opaque and includes apertures for holding plants. The film is rolled out for growing the pants and rolled up for plant harvesting.

Abstract: A reliable conveyor oven minimizes escape of heat by minimizing the time that inlet and outlet openings appear in the baking oven. This may reduce energy consumption by 25%. The baking oven may have a conventional oven and an extension chamber, an outlet opening of the conventional oven acting as an inlet to the extension chamber, the extension chamber having an exit door, the baking oven also having an entrance door defining an entrance inlet. A conveyor holding food items runs through a length of the baking oven. An exit optical sensor may be attached to the extension chamber on opposite sides of the extension chamber such shat an item on the conveyor moving through the extension chamber interrupts a signal between the transmitted and the receiver. The exit sensor may be operatively engaged to a controller for actuating the exit door open and closed rotationally using a pneumatic piston.

Abstract: An automated system for providing a continuous yield of fresh agricultural produce. The system includes a housing including at least one zone for plant growth and at least one zone for holding automated robotic equipment. Robotic equipment includes a robotic device including at least one robotic arm for seeding seeds being stored in a seed reservoir in the seeding locations, for planting seedlings in the planting locations and for harvesting mature plants from the planting locations. Further disclosed are devices and methods for increasing efficiency of plant transfer and minimizing root damage during transfer. Further disclosed are devices and methods for increasing efficiency of plant growing, by providing oxygen dissolved in irrigation water to the plant roots.
