Water Energy Conversion Device

1. #3 - Structures to produce energy from water Design Brief - design a device that could generate power from the movement of water. Build a model of the device in its proposed setting. The model does not need to be a working model. However the idea of what is moving to generate power should be easily understood. Design Criteria - Your model must include: • The device in the proper location and setting where it will generate power. • A scale model of the device. • Moving parts in area that will generate power. (actual water does not need to make contact with the model to show how it works.) • Items clearly labeled.

2. #2 - Structures to prevent damage from water Design Brief - design a product that will stabilize shorelines and reduce the erosion effects of wave action. Build a working model of your erosion control. Design Criteria - Your model must include: • A soil or sand-based shoreline. • Water, with waves striking the shore at different angles. • A scale model of the structure (s) used to stabilize the shore. • The model must visibly demonstrate wave actions.. • Items clearly labeled.

3. #1 - A device to make safe drinking water Design Brief - design and build an inexpensive device for separating and collecting fresh water from sea water or polluted water. Design Criteria - • Sunlight must be the only source of energy. • The device must have a collection system for gathering the fresh water from an impure sample. • Make a plan for disposal of the salt or residue that remains.

4. #4 - A device to contain and cleanup oil spills Design Brief - design a device that will surround and absorb a simulated oil spill. This challenge might involve two steps. • A model of the containment device. • The clean-up process itself. Design Criteria - Your model must include: • The model must be able to contain a simulated oil spill • Remove as much of the oil and as little of the water as possible. • Vegetable is to be used, NOT motor oil.
