1 where are we at and what do we need to do?
Let’s get busy!

2 What do we need to do today?
GET with your teams…… Silver city --- natalie Jack --- SIMcity (will & Zane) Brandon --- model (solomon & elliot)  Kayla --- essay (Natalie) Crystal bay --- jacob Riley --- simcity (sam & jt) Preston --- model (joel, gretchen, taylor, chloe ) Elana --- essay (taylor, chloe, jacob) What do we need to do today?

3 Ocean Generator The best way to capture tidal energy is to place the turbine in a narrow channel between two land masses. When the tide comes in, the water rises on one side of the channel and pours down the channel to the other side. When the tide goes out, the water on the higher side pours back through the channel where the water level has dropped. It is best if the high tide in the channel is 10 to 15 meters (around 30 to 50 feet) higher than the low tide.

Wind Energy

6 Wind turbines operate on a simple principle
Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Click on the image to see an animation of wind at work. So how do wind turbines make electricity? a wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity. 

7 Solar Energy The sun shines on the solar panels, generating “DC” (Direct Current) electricity. The electricity is fed into a solar inverter that converts into “AC” (Alternating Current) electricity. The AC electricity is used to power appliances in your home. Any power not required by your home goes via your home’s switchboard into the mains power grid for others to use.

10 A Maglev train car is just a box with magnets on the four corners.
The magnets are superconducting, which means that when they are cooled to less than 450 degrees Fahrenheit below zero, they can generate magnetic fields up to 10 times stronger than ordinary electromagnets, enough to suspend and propel a train. These magnetic fields interact with simple metallic loops set into the concrete walls of the Maglev guideway. it creates an electric current that generates another magnetic field. Three types of loops are set into the guideway at specific intervals to do three important tasks: 1. first loop creates a field that makes the train hover about 5 inches above the guideway. 2. second loop keeps the train stable horizontally.

11 3. Thirds set of loops is a propulsion system run by alternating current power. Here, both magnetic attraction and repulsion are used to move the train car along the guideway. Imagine the box with four magnets -- one on each corner. The front corners have magnets with north poles facing out, and the back corners have magnets with south poles outward. Electrifying the propulsion loops generates magnetic fields that both pull the train forward from the front and push it forward from behind. This floating magnet design creates a smooth trip. Even though the train can travel up to 375 miles per hour, a rider experiences less turbulence than on traditional steel wheel trains because the only source of friction is air.
