Nicknamed “The Desertron,” this Super collider was a proposed particle accelerator project that would have been the most powerful in the world.

Work began in the 80’s, and by the early 1990’s, around 15 miles of tunnels were bored and 17 shafts sunk on the site. Congress had to pull the plug because the budget had ballooned from a proposed $4.4 billion to $11 billion.

All in all, $2 billion was wasted on this empty building that still has no use.
