Tornado Alley in the United States is a hotbed for cyclone activity, but a professor from Temple University in Philadelphia has proposed the idea of building three walls to protect the area from the devastating effects of twisters. Professor Rongjia Tao came up the with the idea to build three 980 foot high, one hundred mile long Great Walls that would temper the wind, similar to natural windbreakers like hills.

Tornado Alley in the United States is a hotbed for cyclone activity, but a professor from Temple University in Philadelphia has proposed the idea of building three walls to protect the area from the devastating effects of twisters.

Professor Rongjia Tao came up the with the idea to construct three 980 foot high, one hundred mile long Great Walls that would temper the wind, similar to natural windbreakers like hills.

Tao is quoted as saying: “If we build three east-west great walls, one in North Dakota, one along the border between Kansas and Oklahoma, and the third in the south in Texas and Louisiana, we will diminish the threats in Tornado Alley forever.”

The walls would cost several billion dollars to build, but that would be a bargain compared to the billions of dollars in tornado damage that happens annually.

Critics say that the walls wouldn’t work to stop tornadoes, and they could actually add to the destruction by getting pulled into the cyclone, ending up as dangerous falling debris.
