Respiration, Turbines, Solar Power

Respiration/Combustion, Turbines, Solar Power

By Nathaniel Pecoraro

A process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.

​

We will use the same term with the mechanical

​Respiration

Multiple Choice

All living things go through cellular respiration?

• Yes

• No

Multiple Choice

In respiration breathing in, or adding oxygen creates what as a bi-product.

• CO2

• Oxygen

• Nitrogen

• Carbon Monoxide

During combustion, the carbon (C) from the fuel combines with oxygen (O2) from the air to produce carbon dioxide (CO2). The additional weight comes from the oxygen. ... Similarly, the carbon from the fuel combines with the oxygen from the air to produce carbon dioxide (CO2).

​

This process is very similar to how are body goes through respiration

Respiration & Combustion

​Incommon

Both processes are important in the use of energy. Respiration is the body burning the fuels put in and releasing Carbon Dioxide. This happens in all cells. In combustion the fuel is burned directly and carbon dioxide is also produced. Increasing the rate of oxygen being added also increases the rate of usage.

Turbines & Creating Electricity

We do not get electricity simply by burning fuels or creating a nuclear reaction another process must take place to make the energy usable. ​

1. Fuel is burned

2. Water is heated

3. Steam from boiling water spins the turbine

4. Which spins the generator

5. Which Creates electricity​

​

Steam Turbine

Types of power that use Turbines

Nuclear Power - Uses nuclear reactions as fuel

Fossil Fuels - Coal, Oil, Natural Gas and Wood all use this process

Windmills - Are giant air powered turbines

Hydroelectric - Uses the currents of water to power turbines

Geothermal - Uses heat from the earth to power a steam turbine​

Open Ended

In these processes what creates the CO2 in the use of steam turbines?

Discuss with a neighbor.

Open Ended

Why do sources such as wind and hydroelectric not create CO2?

Discuss with a partner.

Solar Panels

Power without a turbine

When sunlight hits a solar cell, electrons in the solar cell begin to move in a circuit. (Flow) This is how a solar cell is able to produce energy.

​

Solar Panels

Multiple Choice

Solar Power uses turbines.

• Yes

• No

With Turbines another can be activated or more fuel can be burned to produce power as needed.

With solar more sun cannot be added so the use of batteries for storage is important. ​
