This instructable is about my research on generating electricity from plants. I want to take this this project and compete in Google Science Fair 2017. I want the intellectual minds of Instructables community to judge and give feedback to the project that i made.
This instructable i have written in the parts as mentioned below:
2. Why I chose the topic
3. Concept and Research
4.Method and Testing
5. Future Use
Step 1: Apparatus
1. Two Plants
2. Aluminium Foil
3. Calculator(For Testing)
Step 2: Why I Chose This Topic?
1. Electricity Generation through plants will make the people adopting and caring more plants
2. In India, 45% of the food is rice and plantation of rice is also the best way to generate electricity as it is grown in wetlands
3. Some big ideas like Green Rooftops can also be possible.
By this methods of paddy fields and green rooftops massive amount of energy can be produced.
Step 3: Concept and Research
Water can generate electricity by selecting proper anode and cathode.
Here we use aluminium foil as cathode and simple copper wire as anode.
Electricity is generated because soil of the plants has water holding capacity. Using anode and cathode as copper and aluminium will generate electricity due redox reaction happening. Anode side contains roots of plants and some bacteria such as lactobacillis bacteria. Oxidation and reduction happens inside due to H2O present in the moist soil.Thus not only plants moist soil or wetlands also generate voltage.
One plant can generate upto 0.5v as shown in the image 2 of this step.
The end with aluminium foil is negative terminal and other copper wire is positive terminal of plant cell.
Step 4: Method and Testing.
Now, we will check the results of the experiment.
We will arrange the cell of two plants by connecting the wires in two plants in series. I have used multimeter for checking the voltages. The experiment was conducted for six hours.
Step 5: Conclusion
The experiment was conducted by me for six hours and the results are as follows
After 1 hour: 0.97v
After 2 hours: 1.01v
After 3 hours: 1.07v
After 4 hours: 1.1v
After 5 hours: 1.23v
After 6 hours: 1.17v and it remained 1.17v.
Step 6: Using Calculator With Plant Power
You can use the calculator using plant power by following this:
1. Take out the cell and solar panel from calculator.
2. Supply the voltages from plants negative terminal to negative terminal of solar panel connections and vice versa.
3. Keep it for 2 hours without using.
4. After two hours the is charge stored in its capacitor and you can use it.
Step 7: Future Use(Green Rooftops)
The idea of green rooftops is shown in the image taken from Google.
If plants would generate electricity and people come to know about it, huge amount of electricity can be produced by green rooftops and some houses can also run from it.
Limitations: Here, I found current of only 0.1mA by applying 100 ohm of external resistance.
