2. How they work Tidal power involves a dam across the opening to a tidal basin. A sluice opens that allows the tide to flow into the basin. As the sea levels drop, the water moves and turns a turbine to generate electricity http://www.odec.ca/projects/2006/wong6j2/tidalAni mation.html - Tidal Power animation http://www.odec.ca/projects/2006/wong6j2/tidalAni mation.html

3. Advantages Some tidal generators can be built into the structures of existing bridges, involving virtually no problems on how it looks Life of tidal energy plant is very long It is an inexhaustible source of energy

4. Disadvantages The turbines can accidentally kill swimming sea life with there rotating blades Salt water causes corrosion in metal parts Frozen sea or low weak tides Very few ideal locations

5. Shipping Container Large reusable steel boxes It is used for the structure of the house Advantages: Ideal building material, and used shipping containers available across globe. Disadvantages: Temperature, building permit, and cargo spillage. Conventional Source Replaced: Wood

6. Natural Lighting Natural lighting from outside It is used to help you see through out your home. It replaces light bulbs Advantages: Reduces electricity cost and saves energy. Disadvantages: No light at night and do not have control over lighting.
