60 projectors at 26,000 watts each were synchronized to create a single seamless image with a resolution of 4592 x 2048 pixels on a 420,000 square foot surface. Wow.

Amazing bit of projection design work.<p>Also: robot semi-truck = a milestone in the twin, linked curves of heightened production and heightened unemployment.<p>Note to self: fix capitalism soon.
For the Grand Coulee Dam's laser light show, they use 4 large frame Coherent Sabre Lasers - 2 red 12-watt Krypton lasers, and blue and green 30-watt argon lasers. That would probably be too complex to set up for this one publicity stunt.<p><a href="http://en.wikipedia.org/wiki/Laser_light_show_%28Grand_Coulee_Dam%29" rel="nofollow">http://en.wikipedia.org/wiki/Laser_light_show_%28Grand_Coule...</a>
Off-topic question: Why do people insist on calling The Hoover Dam "one of the top engineering marvels".<p>Surely, a dam that doesn't even make it into the top-25 tallest dams in the world, and is 57th in the world in power generation is not that impressive?
