Electric Nation (Episode #103H)

KQED 9: Wed, Apr 25, 2012 -- 10:00 PM

Our modern electric power grid has been called the biggest and most complex machine in the world -- delivering electricity to over 300 million Americans over 200,000 miles of high tension transmission lines. But even though the grid touches almost every aspect of our lives, it's a system we know very little about. In this episode, Yul Kwon will travel around the country to understand its intricacies, its vulnerabilities and the remarkable ingenuity required to keep the electricity on every day of the year.

Nation on the Move (Episode #102H)

KQED 9: Wed, Apr 18, 2012 -- 10:00 PM

America is a nation of vast distances and dense urban clusters, woven together by 200,000 miles of railroads, 5000 airports and four million miles of roads. These massive, complex transportation systems combine to make Americans the most mobile people on earth, but much of this infrastructure, built in the 19th and 20th centuries, strains under the weight of our rapidly growing, constantly moving population. In this episode, host Yul Kwon journeys across the continent by air, road and rail. He ventures behind the scenes with the workers who get us where we need to go; he meets innovators creating ways to propel us farther and faster in years to come; and he uncovers the minor miracles and uphill battles involved in moving over 300 million Americans every day.

Food Machine (Episode #101H)

KQED 9: Wed, Apr 11, 2012 -- 10:00 PM

Over the past century, an American industrial revolution has given rise to the biggest, most productive food machine the world has ever known. In this episode, host Yul Kwon explores how this machine feeds nearly 300 million Americans every day. He discovers engineering marvels we've created by putting nature to work and takes a look at the costs of our insatiable appetite on our health and environment. For the first time in human history, less than 2% of the population can feed the other 98%. How does this all work? Who are the men and women who keep us fed 365 days a year? Kwon embarks on a trip across the country to find out.

    • 2/22/17: Fremont Peak tower transmissions, including KQET DT25

      (DT25.1 through 25.3) Recent storms have taken out dozens of trees on Fremont Peak, which in turn have taken down power lines leading to the transmission tower located on the peak. It has been running on generators for several days, and regular trips are scheduled to re-fuel those generators with gas. However, the truck has […]
