Hahaha. Somebody actually took that one seriously and on PBS Newshour presented all of the reasons why the "Solar Wall" is not a very good idea. Things like: it's proposed to be in a sparsely populated location so a huge infrastructure for transmission would need to be created to bring the generated power to locales where it might actually be used. That's what happens when poorly educated people have an extraordinary thought that jumps out of their mouths before being thought about.
