Curious City

The mayor of Chicago declared martial law after the Great Fire in 1871. The military occupation ended days later, after the death of a civilian. We look back at that history and get the help of legal experts to answer these questions: Was Operation Midway Blitz — the Trump administration's aggressive immigration enforcement campaign in Chicago — an example of martial law? What is martial law, anyway?

Suburban Batavia, just 30 miles west of Chicago, used to be known as the windmill capital of the world. But eventually, technological advances took the wind out of the industry’s sails.

In our last episode, we looked into why there are no wind turbines in the Great Lakes even though conditions are favorable. Legal and political hurdles continue to challenge the offshore wind energy business in the Midwest.

Today, we’re going to take an historical look at the wind industry in our region. In modern times, Batavia is known for Fermilab, America’s particle physics and accelerator laboratory. But long before that, Batavia was on the map for hosting six windmill factories.

Batavia Mayor Jeff Schielke and City Clerk Kate Garrett dive into the town’s history. They take pride in the past, but look forward to the future.

Strong and consistent winds that sweep across Lake Michigan could provide significant electricity generation. But there are no wind turbines in the lake or any of the Great Lakes. This Curious City story is made possible through a partnership between WBEZ and Grist, a nonprofit environmental media organization.

Chicago — like so many other frigid American cities — can’t seem to kick its dependence on road salt.

In our last episode, we learned how winter weather on both ends of the thermometer can impact the local economy. Some businesses come out on top during the coldest winters: auto mechanics repairing cars when they hit a pothole, snow plow companies shoveling out small businesses and rock salt providers when the roads get icy.

But chloride from salt is harmful to both our natural and built environments. You’d be hard-pressed to find a cold-weather community that avoids road salt altogether, but we found one!

In this encore presentation, we visit a place way up north, Mackinac Island, Michigan. Dominick Miller, chief of marketing at the Mackinac State Historic Parks, tells us about how the island deals with snow and ice in the winter without laying down a single grain of salt. And it has a lot to do with the fact that cars have been banned on Mackinac Island for over a century.

Each Chicago winter’s wintery-ness has big implications for your sanity and your wallet. That led one Curious City listener to ask us if mild winters have a noticeable effect on the local economy.
