8 football fields in size • waterproof, flexible connectors link 1680 lamps • 12 miles electrical cable • 200 installers
Electrified Grid: “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 to realize the massive project. It was widely acclaimed by critics around the globe and drew tens of thousands of visitors.
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.”

Detail showing a herd of cattle grazing just above the grid. A solar-powered electric fence surrounded the 2400 foot perimeter of the grid to keep cattle from grazing within the array of lamps, which could have led to their injury and/or damage to the installation.
This close up of the 4 foot energy-efficient T8 fluorescent lamps shows how they were joined end on end within a protective and flexible section of rubber washing machine hose. Paralleling the lamps, and running just under them, you can see lines of PVC pipe which carried more than 12 miles of electrical wiring.

1,700 waterproof, flexible electrical connectors are prepared, which linked the massive array of fluorescent tubes end on end. The connectors provided protection from rain, and also allowed 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.
▲ 安装需要12英里的电缆。此外，为向电网供电，一条6吨重的延长电缆沿着高速公路一直连接到山坡的电线上。那条实心铜电缆足有一个男人前臂粗， 价值5万美元；由加利福尼亚州瓦列霍的美国海军造船厂借给了该项目。
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.
