Types of Energy

  • Nuclear Energy: Energy released from the nucleus of an atom through nuclear reactions.

  • Renewable Energy: Energy derived from natural resources that replenish over time, such as solar, wind, hydro, geothermal, and biomass.

  • Fossil Fuels: Non-renewable energy sources formed from the remains of dead plants and animals, such as coal, oil, and natural gas.

  • Hydroelectric Energy: Energy generated from the movement of water through turbines.

  • Solar Energy: Energy derived from the sun through the use of solar panels.

  • Wind Energy: Energy generated from the movement of wind through wind turbines.

  • Geothermal Energy: Energy derived from the heat of the Earth's core.

Horses vs. Oxen

Horses

  • Horses were made a useful draft animal due to the invention of the Throat + Girth Harness/Shoulder Harness

  • Horses are generally very fidgety and high maintenance

  • Horses are very fast workers

Oxen

  • More pliant, larger, calm

  • Stronger than horses

  • Slower than horses

  • Require more food

Invention of “Horsepower“

  • When James Watt was trying to market his steam engine as a replacement for the horse, the created the unit “horsepower“ to measure the strength/power of a machine

  • 1 hp = 745.7 watts

Weather vanes/Anemometers

Wind has both speed and direction. Anemometers measure wind speed and wind vanes measure wind direction. A typical wind vane has a pointer in front and fins in back. When the wind is blowing, the wind vane points into the wind.

The weather vane is made up of a tail and arrow. The tail fin catches the wind and the arrow points toward the direction the wind is blowing FROM.

If the arrow on the weather vane is pointing north then it means there is a north wind. In other words, the wind is blowing from north to south.

Knowing the direction the wind is blowing from can be very useful for a variety of reasons especially for farmers, pilots and meteorologists.

Meteorologists use wind direction to get a sense of what kind of weather is coming. Generally speaking, cold air is located to the north and warmer air is located further south.

If the weather vane shows wind blowing from the north, one can say colder air is moving in. This is especially true if the wind direction recently changed to the north, usually a sign that a cold front just passed by.

Pilots use another tool that works much like a weather vane called a wind sock. It tells pilots what direction the wind is blowing from so they know which runway to use for a safe flight.

Weather vanes are often accompanied by another weather instrument called an anemometer. An anemometer measures the wind speed. It uses tiny cups that spin in a circle and the faster the cups spin, the strong the wind.

Pros + Cons AC and DC Currents

Pros of AC Currents:

  • AC currents are more efficient for long-distance power transmission.

  • AC currents can be easily stepped up or down using transformers.

  • AC currents are less likely to cause electrocution due to their cyclic nature.

  • AC currents are more suitable for powering household appliances and electronics.

Cons of AC Currents:

  • AC currents are more difficult to store in batteries.

  • AC currents are more prone to power loss due to resistance in transmission lines.

  • AC currents can cause electromagnetic interference in sensitive electronic devices.

  • AC currents can be more dangerous in high voltage applications.

Pros of DC Currents:

  • DC currents are more efficient for short-distance power transmission.

  • DC currents can be easily stored in batteries.

  • DC currents are less prone to power loss due to resistance in transmission lines.

  • DC currents are more suitable for powering electric vehicles and renewable energy sources.

Cons of DC Currents:

  • DC currents are more difficult to step up or down using transformers.

  • DC currents are more likely to cause electrocution due to their constant nature.

  • DC currents can be more expensive to produce and maintain.

  • DC currents can cause more heat buildup in electrical components.
