Edison’s early movie projector, Tesla’s alternating ­current, Ferris’s first massive steel wheel – we’ve come a long way from the scientific and technological marvels that drew huge crowds to Chicago for the 1893 World’s Fair.

This summer, Wired heads to the historic city to host NextFest, an exposition that brings together innovations from top scientists, researchers, and entrepreneurs. Building on the success of last year’s NextFest in San Francisco, we’ll offer more than 100 exhibits about the future of exploration, entertainment, transportation, science and medicine, communication, design, defense, and ­imagination (a pavilion dedicated to developments by NextFest sponsor GE). On the pages that follow, we’ve highlighted the cool things you’ll be able to see, touch, and in some cases test-drive.

Join us June 24-26 at Chicago’s Navy Pier.
