Slide 1:Bay of Fundy & Tidal Power Picture Source: http://www.canada-photos.com/data/media/11/fundy-bay_175.jpg Tracy Hanaoka
Slide 2:What are ocean tides? The rise and fall of seawater
Caused by gravitational pull between the Earth, moon, and sun
Moon causes the rhythm and height of the tides
Different types of tides (Solar, Lunar, Neap, etc.) Information source: http://www.physicalgeography.net/fundamentals/8r.html Picture source: http://farm4.static.flickr.com/3587/3626771198_ac46a8ce80.jpg
Slide 3:What is the Bay of Fundy? Picture: http://www.globusjourneys.com/Common/Images/Destinations/bay_of_fundy_novascotiaca.jpg Home to largest tides in the world
Located on Atlantic coast (near North America)
Recently listed as one of 7 Wonders of Nature Information: http://en.wikipedia.org/wiki/Bay_of_Fundy http://www.bayoffundytourism.com/tides/
Slide 4:Why is the Bay of Fundy a special example of ocean tides? Picture: http://sedulia.blogs.com/photos/everywhere_else/harborville_bay_of_fundy_at_low_tide.html
Information: http://www.bayoffundytourism.com/tides/ http://en.wikipedia.org/wiki/Bay_of_Fundy 100 billion tons of seawater comes in and out of the Bay
It’s highest tide was 21.6 meters
People proposing to use tidal power as electricity generator
Slide 5:What is tidal power as an alternative energy source? Picture: http://storageeffect.media.seagate.com/files/2008/11/tidal_wave_800x480.jpg Tidal wave can go into mechanism, spin wheels/propellers and generate electricity
At least 6% of the United States power comes from this type of energy source
Also known as “Hydropower” Info: http://tonto.eia.doe.gov/kids/energy.cfm?page=hydropower_home-basics
Slide 6:Pros of tidal power as an alternative energy source Eco-friendly
Can be harnessed from many sources
Does not require much manual labor
Relies on nature Picture: http://www.modcomm.com/UserFiles/Image/ClipArt/go%20green.jpg
Slide 7:Cons of tidal power as alternate energy source We can’t control how large the tidal waves will be
Since this energy source is renewable and controlled totally by the environment and weather, we can’t predict exactly how much energy can be produced from hydropower Picture: http://www.kktravels.com/images/go_green.jpg
Slide 8:Tidal power in the Bay of Fundy Picture: http://regmedia.co.uk/2007/08/23/seagen_tidal_power.jpg The Bay of Fundy has been chosen to start a project where the tides will be used to create power
Tidal turbines set up
