This video continues the series on the power grid by diving deeper into the engineering of large-scale electricity generation. The importance of electricity in our modern world can hardly be overstated. What was a luxury a hundred years ago is now a critical component to the safety, prosperity, and well-being of nearly everyone. Generation is the first step electricity takes on its journey through the power grid, the gigantic machine that delivers energy to millions of people day in and day out. So how does it work?

This video explores the protective systems that keep the power grid from self destructing. We usually think of the power grid in terms of its visible parts: power plants, high-voltage lines, and substations. But, much of the complexity of power grid comes in how we protect it when things go wrong. When your power goes out, it’s easy to be frustrated at the inconvenience, but consider also being thankful that it probably means things are working as designed to protect the grid as a whole and ensure a speedy and cost-effective repair to the fault.

In civil engineering, quicksand is more than just a puddle of mud! The "quick condition" occurs when seepage reduces the effective stress of a soil. This can lead to some dangerous conditions, especially if the seepage causes piping erosion to occur at a dam.

Expansive soils cause more property damage per year than earthquakes, floods, hurricanes, and tornadoes combined. Expansive soils are a slow-moving geologic phenomenon, which makes them not very news-worthy. However, they still cause a tremendous amount of damage to buildings and the public infrastructure we rely on every day.

This video discusses the purpose and function of elevated water storage tanks. The job of finding enough water, making it safe to use, and then reliably distributing it to the system customers with almost no downtime is a monumental task that requires a lot of infrastructure. And, probably the most visible component of a public water system is the elevated storage tank, also known as a water tower.

This video gives a quick overview of how we build underwater structures. Oceans, rivers, and lakes are often beautiful, but they’re not necessarily convenient places to build things. Yet, many types of the infrastructure we depend on every day, including wharves, bridges, and dams, are founded below the water. How do they do it? On this episode, we're talking about different types of underwater construction, including cofferdams, diversions, caissons, and drilled shafts. Whether the construction site is on the bottom of a lake or river, or simply located in the floodplain and only at risk during extreme weather, engineers and construction contractors put a significant amount of thought and consideration into the feasibility and costs of managing this water.

Discussing some of the fascinating engineering that goes into overhead electric power transmission lines. In the past, power generating plants were only able to serve their local areas. As power plants grew larger and further away from populated areas, the need for ways to efficiently move electricity over long distances has become more and more important. Stringing power lines across the landscape to connect cities to power plants may seem as simple as connecting an extension cord to an outlet, but the engineering behind these electric superhighways is more complicated and fascinating than you might think.

This video explores a primer on one of the most important companions to civil engineering: land surveyors. Conventional measurement tools like a tape measure and protractor don't work for large civil structures and public works projects. Surveying is essentially the science of measuring big stuff. In this video I give a quick explanation of how surveying works and show a few ways you can do your own leveling survey at home. No sines, cosines, or tangents required!

Water hammer can work in both directions, and I only discussed one of those in the previous video (https://youtu.be/xoLmVFAFjn4). This episode revisits that demonstration to show how water hammer can form a vacuum pressure in a pipe. Momentum carrying fluid away from a valve wants to keep going even after the valve is closed. This generates a negative pressure than can cause major damage!

Dirt is probably the cheapest and simplest construction material out there, but it's not very strong compared to other choices. Luckily geotechnical engineers have developed a way to strengthen earthen materials with almost no additional effort - Mechanically Stabilized Earth (aka MSE or Reinforced Soil).
