(total area = 8 football fields) 
Luminous Earth Grid, an array of 1,680 energy-efficient fluorescent lamps, swept over an area equal to 8 football fields, 50 miles north of San Francisco. Said the artist, “I see the project as a poetic statement on the potential harmony between technology and nature.” Over a five year period, Williams launched a rigorous fund raising campaign throughout Northern California, and raised nearly $500,000, including in-kind contributions, to realize the massive project. It was widely acclaimed by critics around the globe and drew tens of thousands of visitors.

“It is unquestionably the most ambitious work of environmental art in the San Francisco Bay Area since Christo’s Running Fence. It is a joyful thing.” 
— Allan Temko, Pulitzer Prize-winning critic, San Francisco Chronicle

Said Williams, “The glowing green grid can be seen as an icon of computer imaging technology, which in this ‘real life,’ incarnation, gently melds with the flowing shape of a lovely landscape... a dream-like vision of symbiotic unity.”
“It emanates a sense of the romantic sublime with its aura of surprise and wonder. It is a very, very beautiful thing. I think people are very lucky to have a chance to see such a fine work of art.”
— Peter Selz, former curator, Museum of Modern Art, New York.

“Our emotional connection to an increasingly technologically dominated life would not be addressed by most artists until years later. This makes the Luminous Earth Grid, by American artist Stuart Williams, all the more remarkable.”  — iGNANT, Berlin

1,700 waterproof, flexible electrical connectors are prepared, which will link the massive array of fluorescent tubes end on end. The connectors must provide protection from rain, and also allow the linear array of 4 foot tubes to bend and incrementally match the roll of the terrain. Photo © Stuart Williams.

Tens of thousands of pounds of steel hardware, electrical cable, ballasts and energy-efficient lamps had to be trucked to the site. Many dozens of truck loads later, the lengthy on-site installation work commenced. On-site installation took one month. Photo © Stuart Williams.
12 miles of electrical wiring were required to facilitate the installation. In addition, a 6-ton extension cable was strung down the mountainside and hooked into existing power lines along the freeway to bring power to the grid. That solid copper cable — the diameter of a man's forearm — was valued at $50,000, and was loaned to the project by the U.S. Naval Shipyards in Vallejo, California. Photo © Stuart Williams.

As the grid neared completion, the three lead electricians and the artist gathered for a photo.
