Internal Structure

The internal structure of the main body's cylindrical part consists of:

• 10lt water tank in the center of the cylinder, full of water at 5pH
• low pressure water-pump in the water tank
• two 6lt oxygen carbon fiber tanks that collect the oxygen produced by the plants
• one 6lt carbon fiber tank storing carbon dioxide (CO2) for several purposes
• inverter DC/DC 12V
• six lithium-ion 12V (10A) batteries of 30Ah each
• power supply for electronic devices
• arduino mega
• auto-doser
• pneumatic system for opening/closing the external covers
• eight solenoid air valves for controlling the pneumatic system
• dehumidifier for stabilizing internal humidity
• solenoid valve, with regulator, connected with the oxygen tanks in order to clean the zeolite filter of the VPSA system
• solenoid valve, with regulator, connected with the CO2 tank in order to adjust pressure internally
• resistance in order to stabilize interior temperature
• two 500ml tanks each for storing fertilizers each of them with different ratio of nitrogen, phosphorus, potassium (N-P-K) and other micro-nutrients
• one 500ml tank with liquid oxygen supplement (hydrogen peroxide and other ingredients) in order to enrich water with oxygen
• two 500ml tanks, one with pH-up and one with pH-down liquid for adjusting water's pH
• tubes connecting each fertilizer tanks with the water tank
• ventilation system connecting the dome and the hemispherical part
• Vacuum-Pressure Swing Adsorption (VPSA) oxygen concentrator
• system of tubes (becks) adjusted on the panels in order to clean the panels from dust using CO2

The internal structure of the main body's hemispherical part consists of:

• spiral container where the roots of the plants find the right environment to grow
• one closed-end tube following the spiral container which transfers the water
• 25 sprinklers on the tube
• 24 pots with holes placed inside the spiral container, each between two sprinklers, for storing the plants roots
• rock-wool or hail cubes or clay pebbels inside the pots where the seeds are planted
• one platform that moves above and along the spiral helping the harvest process (HAP)
• a sharp razor adjusted on the movable platform in order to harvest the plants
• small electric motor (12V DC motor) adjusted on the movable platform
• cable for power the electric motor
