Exhibit located on the countertop of "The Dam" exhibit, in Centro Ciência Viva de Tavira.

This exhibit demonstrates how one can generate electricity with a rather simple device, like a magnet rotating inside a copper coil, which is connected to some LED lights. The user turns the handle to generate electricity, which lights 4 LED light projectors, and he may check how much electric tension and current he's generating, by looking to the voltmeter and the ammeter at the top of the exhibit.

Exhibit's scale model overview. The user pushes one button, and the water cycle begins its work. Water starts to evaporate from the lake, forms a cloud above, which travels up to the mountains while water vapor condenses. By arriving at the mountain, rain starts to fall, and water starts to travel down the terrain until it reaches the lake. The exhibit actually works on its own water cycle, but still we added rainfall from a water tank above, to enhance the user's experience and to better demonstrate how water cycle really works in our world.

Water evaporation and condensation.

Water precipitation in the form of rainfall and fog drip, and surface runoff.
