University of West Florida Symposium 2017
The Transpiration Process Conclusion
Elizabeth Demaray Transpiration Collector is an open source design for a plant-based H2O purification and transpired water collection. I feel that the greatest purpose for this experiment would be used as a renewable resource for consumable water. How do we use the transpiration process of a plant to collect water for consumption? Thanks to Elizabeth, we discovered that the Peace Lily produces an optimum amount of vapor that can be collected and measured. How do we collect the water that is produced by the plant? Using the basic instructions that were provided by Elizabeth, we were able to build a basic prototype to monitor the transpiration process of the Peace Lily.
Miraculously, we discovered that the plant was transpiring a high amount of water vapor. We have a hypothesis to build a better apparatus that would maximize the collection. Thanks to the collaboration of the biology department, we discovered that we could increase the amount of the transpiration process of the Peace Lily by adding a stimulus. Hypothesis, to maximize the transpiration rate of the Peace Lily, we need to use a transparent plastic for the enclosure to allow sunlight (photosynthesis), a frame to keep the plastic cover off of the plant leaves, a device to capture the condensation created by the water vapor. We created a transpiration framework for the Peace Lily utilizing a running hypothesis to maximize the transpiration rate. The experiment was successful as we changed a few variables such as removing the plant from a greenhouse setting into a temperature control room. The transpiration rate was slower, however, the plant still produced a higher amount of water in this updated prototype. Conclusion, the current data gave us a realistic idea of key variables to maximize the transpiration rate. We discovered that the greenhouse temperatures although higher produced an increase in water vapor, the volume of the container should allow air- flow which directly affects the transpiration of the plant after enclosed over a period of time. The plant needed a break from the enclosure in order to prolong the plant's life cycle.
Finally, we finished our transpiration prototype using a heat forming method to mold plastic into a dome shape. I am including images below of the 2017 Symposium that we participated in demonstrating the transpiration process. We were able to set-up our model along with visual aids to explain the transpiration process in a presentation environment. My team was also able to enter our transpiration model into UWF's Art departments Pop-Up Show 2017 (images are below).
