Summary of findings
Based on our experiment, our system has the ability to sustain itself(including powering of the lighting) as long as there is flowing water with sufficient water pressure.
Our design can be used to help rural places generate electricity due to the fast charging of the battery as long as there is sufficient pressure going through the generators. It can even be used in urbanised states where there are water pumps to generate the water pressure needed when the sanitary system is in use. This will help power the system. The only knowledge needed for maintenance of the system is changing of the batteries in case of a leak and the changing of bulbs should a bulb fuse assuming no wires are damaged in any way.
Our design can also be used to save utility costs and is eco-friendly by saving the amount of fossil fuels burned for electricity by making use of the water in the toilet. Our design is also simple to move around and install as it does not require a lot of space. Our product can also be made by using recycled plastic and/or rubber. Materials needed are cheap and easily found anywhere.
Our product can also be used in sewers after the water is filtered and the electricity generated can be used to power some parts of the country (Eg. in Singapore, it can be placed in the canals and reservoirs and due to the large amount of canals and drains here, we should able to generate huge amounts electricity which can be put to good use). Our product can be used in many areas like in a Singaporean household. As long as sufficient water pressure is generated, you can make your own system to water your plants and connect your system to another main one. This way, you can make use of the dirty water to generate electricity and at the same time water your plants.
Suggestions for Further Studies
It would be for the best if we could find a generator that would be able to generate more electrical energy to power more powerful bulbs and to charge up larger batteries with the same amount of water used. We will be able to power a small house or office instead of just a small sanitary system. Being able to do so would greatly benefit the whole purpose behind this project's idea.
We could learn how to generate a stronger water pressure without the use of a water pump so people living in the poorer regions will not be required to purchase water pumps due to cash constraints.
