The document discusses a research project on harnessing energy from plant photosynthesis through compost and different electrode setups. It outlines the experiment's design, materials, methods, and the positive impact of compost on plant growth, voltage, and current intensity. The findings support the hypothesis that increased biological activity and larger electrodes enhance electrical output in plant cultivation.

2. Introduction

3. Biological activity hides richnesses in terms of
obtaining energy. So why not investigated further?
When plants photosynthesize, they generate a
degradation which creates a flow of electrons,
creating a natural battery. This can be used to
obtain energy.

4. One only had soil and the other
had soil with compost. We also
put different electrodes in
them to see how it changes its
growth and the electricity it
can generate.

5. Ohm's law
With this experiment we also want to demonstrate Ohm's law. By
having bigger electrodes in some of the plants, the resistance of
these is lower thus having a higher intensity.

6. Previous studies

7. PREVIOUS STUDIES
Use larger pots
Use flat electrodes instead of tubes
Try other treatments (plants)
In the year 2022, research was carried out within the
CAOSll project. At the end they came to the conclusion
that the experiment could be improved so they proposed
some changes among which stand out:
cm of the plant (300cm - 500cm)
We replaced the cylinders and screws with iron mesh
and copper foil.
Using peppers instead of onions
Taking this changes into account

8. Objectives +
Hypothesis

9. By increasing the biological activity of the soil by adding
compost and a plant, we will obtain a higher current
intensity.
By using electrodes with a larger surface area, we will obtain
a greater flow of electrons.
To improve previous experimental methods to further investigate
how we can harness electricity in the process of plant cultivation.
To check how the growth of bell pepper plants and the biological
activity of the soil are positively affected by bio-waste compost.
To test whether the compost increases photovoltaic energy
production.

12. Method
We named all the pots by dividing them into 4 different
groups. There are 4 pots in each group. The groups depend
on the type of soil treatment and the electrodes they had.

14. Methods
For the electrical measurements we connected the plants in series by
connecting the ends to an electrical measuring machine, and noted
their voltage and amperage, differentiating between the types of
substrate and electrodes.
To measure the height we used a meter, and to count
the fruits, leaves and flowers, we did it manually.
The last thing we did was to cut the plants and then
weigh them.

22. Conclusions
At the conclusion of the project, we have observed that our
hypothesis on how the use of compost in the plant affects its
growth, voltage and current intensity were correct, since
the group of plants 2 and 4 which had this, show an
improvement in their growth, the number of flowers and
fruits, also an increase in the intensity of current and
voltage is observed, which is very positive for our project,
since with the increase of this we get a higher yield in our
"natural battery".
