Discover how the English Channel Tunnel was built and the engineering challenges of building a 200 kilometer long tunnel underwater.--Flanked by two powerful nations, the English Channel has long been one of the worlds most important maritime passages. Yet for most of its history, crossing was a dangerous prospect. Engineers proposed numerous plans for spanning the gap, including a design for an underwater passage more than twice the length of any existing tunnel. Alex Gendler details the creation of the Channel Tunnel.Lesson by Alex Gendler, directed by Studio Kimchi.Animator's website: https://studiokimchi.com/Sign up for our newsletter: http://bit.ly/TEDEdNewsletterSupport us on Patreon: http://bit.ly/TEDEdPatreonFollow us on Facebook: http://bit.ly/TEDEdFacebookFind us on Twitter: http://bit.ly/TEDEdTwitterPeep us on Instagram: http://bit.ly/TEDEdInstagramView full lesson: https://ed.ted.com/lessons/how-the-world-s-longest-underwater-tunnel-was-built-alex-gendlerThank you so much to our patrons for your support!
