Physicist Wants to Build 1,000-Foot Walls to Prevent Tornadoes from Destroying the Midwest
wants to build massive 1,000-foot high, 165-foot thick walls around the American Midwest to keep the tornadoes out. It may sound silly, but this proposal is based on the fact that, despite similarities in topography between the Northern and Eastern China plains and the American Midwest, the Chinese plains have fewer tornadoes . In part, this is because the Chinese Plains are surrounded by mountain ranges which slow down passing winds enough to prevent formation of tornados.
