Period 5 Poster Presentation Notes

Alayna, Tra, Camille

Poop Power Plant

Washington, D.C.

Power = depends on how much poop goes in

Food for bacteria ==> Methane or carbon ==> Heat or Electricity

(Chem Pot. E.)

==>

(Chem Pot. E.)

==> (Thermal K.E. or Electrical K.E.)

Jay, MacKenzie, Justin

Solar Power Plant

Household system

175 Watts per panel x number of panels = power

UV rays from sun	==>	Electrons are knocked free	==>	Flow of electricity
(Radiant Energy)		(Kinetic Energy)		(Kinetic Energy)

Andrew and Arielle

Hydroelectric Dam

Three Gorges Dam

22,500 MW (98.1 TerraWattHour per year)

Water flow	Turbine	Electricity

Aliyah and Tashana

• Solar Panel
• Smaller crystals of CuIn, GaSe, Silicon
• Light excites electrons to higher energy level
• This creates electricity for the house
• N-type and P-type semiconductors
• P-type silicon is missing an electron
• N-type silicon has an extra electron
• Electrons move from the N to the P crystals
• Example:
• Neighborhood house
• 4800 Watts = 4.8 kW

Sun light	Electrical current
Radiant	Kinetic Energy

Robert and Jeremy

Nuclear Power

• Waterford, CT
• 2,015 MW
• Similar to coal (steam spins turbines)
• Uranium gives off heat to make pressurized steam to boil
• Steam turns the turbine
• Turbine turns magnets in the generator
• Magnets excite electrons in copper coils
