Sound waves are transferred to

a thin metal disc called the diaphragm. This converts the energy into electric energy.

Solar Power

• Two main types of solar power, thermal and photovoltaic

• Solar thermal is when solar radiation is used to directly heat materials that can then use the heat to heat up water, air, or wall.

• Solar photovoltaic is when solar radiation is used to make energy via electricity, as seen by my model on the left.

• Conversion efficiency can be calculated by the formula power out / solar power in.

• Most methods of collecting solar power require elevation and/or large, open areas to maximize collection.

• 4 Million times more energetic than a chemical reaction such as burning coal, oil, gas
• Does not give off any greenhouse gas emissions.
• Much lower risk for nuclear proliferation compared to current nuclear reactors
• Difficult to achieve and sustain this reaction.
• 59 megajoules of sustained energy for five seconds is enough energy to power 35,000 homes during that time
