Fun with optical illusionsBelow is an artist's rendering of the proposed Knauf Fiber Glass insulation factory as it would appear in the City of Shasta Lake, California. This graphic appears on the cover of Knauf's Environmental Impact Report. The report was created by CH2M Hill.If you look real close, you can see the factory's stack. It looks pretty small compared to the warehouse on the right which doesn't even fit in the picture.
 The picture above is kind of pretty, but it doesn't give us a very good idea of the stack's size. Lucky for us, the Knauf Environmental Impact Report also lists the stack's basic dimensions. Below is an excerpt from the Knauf EIR.
 (Note: "reddish-brown color" is a clever way of saying "rusty") I thought it would be interesting to compare the size of Knauf's stack with the size of a human being. Below is a illustration that makes the comparison.
Knauf's stack would be larger in diameter than a penstock at Shasta Dam
 The penstocks at Shasta Dam are 15 feet in diameter. They are large enough to permit passage of a modern school bus. Because of this fact, many people have marveled at their enormous size. Now check this out, the skinny end of Knauf's stack would be 17 feet in diameter. This is 2 feet larger in diameter than a penstock at Shasta Dam. The base of Knauf's stack would be 22 feet in diameter. That's 7 feet larger in diameter than a penstock at Shasta Dam.
