1. The Green Machine is a starter kit that allows children to assemble an aquaponics system with a fish tank, plants, and sensors. 2. The system works by fertilizing the water from the fish tank for the plants, and the plants clean the water for the fish in a closed loop. 3. A mobile app and subscription models are proposed to interact with and maintain the systems, with the goal of installing them in primary schools.

5. Our solution

6. Green Machine

7. 1. Get a Starter kit
GreenBox
GreenFishTank
GreenBrains
(Arduino)
GreenPump
GreenLights (LED)
WaterSensor
Seed pots
(like Senseo pads)

8. 2. You assemble it with your child

9. 3. Add green things
The fish fertilize the water for the plants
and the plants clean the water for the fish
The GreenBrain controls the
flow of the water between the fish tank and
the plants
The GreenBrain controls the lighting so the
plants will grow

10. 4. And start the machine!

11. How it works …
The fish fertilize the water for the plants
and the plants clean the water for the fish
The GreenBrain controls the
flow of the water between the fish tank and
the plants
The GreenBrain controls the lighting so the
plants will grow

12. How it works …
1 The GreenBrain controls the GreenPump

13. How it works …
2
The fertilized water is pumped from the
fish tank to the plants

14. How it works ….
3
The plants use the fertilized water to grow
and they clean it for the fish.
Water flows back to the fish tank through
Gravity.

15. How it works ….
4 The GreenBrain controls the lighting so the
plants will grow inside
