5.1 Summary of Findings:
The results showed that the 3 factors tested does not affect the power output of a potato battery.
5.2 Practical Applications:
As a potato battery can power an LED light, potatoes can be used to power lights that utilize LEDs for ambient lighting in poor rural areas. Since mold and being dried out does not affect the power output of a potato battery, using potatoes to power ambient lighting in rural areas increases the length of the intervals a device powered by a potato can be used before it needs to be changed for a new power source. This in turn reduces the time taken up by maintenance and cost of obtaining a new power source ( potatoes are cheaper and kerosene), all benefits to the rural poor living in the area.
Also, the convenience of the grocery and obtaining food in urban areas usually means that there is a potato somewhere in the home. When a blackout occurs, potato batteries could be used as a power source for home emergency lighting.
5.3 Areas for further studies:
These benefits to the rural poor as well as the urban population can be further studied by exploring the different means to increase a potatoes power output, such as whether a potato can be refined (e.g. blended, squeezed for its juice) in order to increase it’s power output or what electrodes could be used in the potato battery components to increase their voltage output as well as whether their location on the potato affects their internal resistance.
Further research can also be conducted on what other kinds of commonly available organics that are high in potassium content, such as lemons, oranges, bananas, carrots and watermelons can be used to generate power and whether they are more efficient and/or effective at generating more power than a potato.
Research and development into creating products adapted to be powered by a potato can also be done, increasing the feasibility of a potato battery being employed.
