Earlier this week, the State of Nevada granted a self-driving Freightliner tractor trailer rig a license--the first such license in the United States. To promote this event, Freightliner piloted the truck over the Hoover Dam on the Colorado River. As the truck passed over the dam, projectors shined on the face of the dam, turning it into an enormous projection screen.
That projection earned a Guinness World Record for the brightest light projection. The Associated Press reports:
The company said 60 projectors used 1.17 million lumens — equal to about 1,400 household lightbulbs — to stretch videos, images, animation and an American flag onto the surface of the modern construction marvel finished in 1935 on Nevada and Arizona's border.
The program included live footage and recorded video.
Daimler says the video projection was equal in size to nine football fields or more than 87 average-sized IMAX screens.
