Hier ein weiterer Auszug, diesmal das “Evapo-Transpiration – Concept”. Es geht um den Stoffwechsel der Pflanzen, im Speziellen um deren Wasserhaushalt. Und wie dieser so wassersparend wie möglich gestaltet werden kann, denn: “Every drop counts!”.
Ein positiver Trend schient sich abzuzeichen: Forschungsinstitute in Wien und auf internationaler Ebene legen immer mehr Wert auf die Wissenschaftsvermittlung.

understanding water evaporation, plant transpiration and water movement tracing…
please take into account: we will have a voice actor explaining the overall situation as well as
supporting the viewer with additional explanations about the various details.
this text is not prepared so the following animation-concept relies on parts yet to come.
Explaning transpiration, evaporation and water flow tracing:
1. We start with a rainfall and zoom in onto one single drop. Meanwhile the narration explains the importance of water and water saving due to increasing the usage efficiency. 60% are lost! We zoom into the molecular level and explain the difference between light and heavy h2o molecules ( including the internal atomic structure of light and heavy versions of hydrogen and oxygen) as well as providing some basic information about the natural ratio and their origins. The rainfall reaches the soil and the plant’s roots absorb some of it. 2. We follow the water trough the plants roots through the whole plant. We zoom out and see the transpiration. We zoom in again on a molecular level and can observe how the different h2o molecules (light and heavy) behave underneath the plant’s surface. The lighter can easily pass trough the surface but some of the heavier cant; they get deflected by the surface and stay inside. We zoom out a bit more so we can see plenty of both molecules. The heavier molecules get highlighted so we can visualize of a ratio between both types. In addition a graphical overlay will further visualize the ratio over time.
3. We zoom out and „fly“ to a water reservoir (plantage pond) to see further evaporation of water. We zoom in and repeat the explanations similar to scene 2. We zoom out again and „fly“ to our next evaporation scene: the water canal. We will repeat the explanation again. Once again we zoom out to observe evaporation on moist soil. Further explanation about the statistical ratio-data and its appliance will support the viewer and prepare the viewer for our conclusion.
4. We zoom out to see the entire field form a birds perspective. With the data obtained, we now have an accurate idea about how water flow from rain and irrigation systems actually work and which routes they take. Graphical overlays and additional water movement simulation will explain how the gathered data can help in crop field management desicions.,
5. We zoom out to see a large area of a crop field and gradually flood it with the flood-irrigation system. At the peak we show animated evoporation. We zoom back to a smaller scale to the site where the laser is located. After explaining how it works we realize that an enormous amount of water is wasted using such irrigation systems. How can you minimize such loss? Change the irrigation method! We zoom back out to our flooded flield and replace the old irrigation system with a drip irrigation system. The laser measures an significant decrease in lost water. We zoom in to a detail of the dripping tubes. We can observe the more efficient irrigation happening and our speaker will explain how much water can be saved on an average crop field. The millions of litres could be visualized in comparison to an average household, annual city spendings or, if summed up globally , the entire planet’s freshwater use.
the following pictures are very draft versions to underline the animation concept, the pictures below do not represent the final quality and are for clarifying purpose only.
