Week 1: How It All Starts and Ends

The course starts by looking at the basic principles of energy sources at the level of the atoms and molecules. This shows how everything from wind energy to nuclear energy share the same basic concept. We then go on to blow some stuff up and explain the statistics of what forms of energy are used around the world – who has them, who uses them, and who produces them. “How Things Work” segments start with a bang (fireworks) and then get both louder (bell towers) and softer (silencers)....

Week 2: Getting and Using the Power

Here we dig into the two most frequent uses of energy and how to make it into useful devices, namely, the engines in cars and making electricity. How exactly does an engine work, and are there ways to make them better? How do they tie into the basic physics from the first week? We also find out what is so “smart” about the electric grid and how it is changing over time. “How Things Work” features airports, hybrid cars, and really flashy electricity (i.e., lightning!)....

Week 3: Why Coal Is Dirty

Fossil fuels still dominate the energy landscape, and this week we go into them deeply, starting with coal. What is it? Where does it come from? Who has it? Who uses it? What problems does it cause? We will explore global warming and, more importantly, what can be done about it. You get to control the world in a climate model and see how bad (or how good) the future can be. “How Things Work” takes you into a coal power plant, a trash transfer station, and a waste treatment plant, so grab your shovels and hard hat, and let’s dig in!...

Week 4: Oil and Gas – With Us Forever?

Oil and natural gas are the most used and most popular energy sources in the world. What are they? Where do they come from? Who uses, needs, and makes them? All the facts and the controversies over pipelines and hydraulic fracturing (fracking) are discussed in detail. All of this is tightly tied to economics so grab your wallets – you will really see where your money goes! "How Things Work” takes us to high places – an observatory, a cell phone tower, and a laser light show!...
