Cheyenne to Host Massive AI Data Center Using More Electricity than All Wyoming Homes Combined

William Attardi on August 29, 2025

An artificial intelligence data center that would use more electricity than every home in Wyoming combined before expanding to as much as five times that size will be built soon near Cheyenne, according to the city’s mayor. With cool weather — good for keeping computer temperatures down — and an abundance of inexpensive electricity from a top energy-producing state, Wyoming’s capital has become a hub of computing power. The city has been home to Microsoft data centers since 2012. An $800 million data center announced last year by Facebook parent company Meta Platforms is nearing completion. The latest data center, a joint effort between regional energy infrastructure company Tallgrass and AI data center developer Crusoe, would begin at 1.8 gigawatts of electricity and be scalable to 10 gigawatts. A gigawatt can power as many as 1 million homes. But that’s more homes than Wyoming has people. The least populated state, Wyoming, has about 590,000 people. But this proposed data center is so big, it would have its own dedicated energy from gas generation and renewable sources.  Cheyenne to host massive AI data center using more electricity than all Wyoming homes combined | AP News

Wyoming’s First New Coal Mine in Decades to Extract Rare Earths

William Attardi on July 16, 2025

The developer of what would be the first new coal mine in Wyoming in decades is launching a potentially half-billion-dollar effort to extract rare earth metals from the fossil fuel that is crucial for tech products and military hardware. The only operating U.S. rare earths mine is at Mountain Pass in California. Nearly all of the nation’s supply comes from China, the source of nearly 90% of the world’s supply.

The Statue of Liberty was made with copper but due to oxidation, it turned green.

When the “Lady in the Harbor” first arrived in New York in 1886, she didn’t look like the mint-green icon we know today. In fact, for the first twenty years of her life, she stood as a towering, metallic beacon of reddish-gold. Designed by French sculptor Frédéric Auguste Bartholdi and engineered by Alexandre Gustave Eiffel, the statue was a gift from France to America. To build her, Bartholdi chose copper for three practical reasons:

  • Malleability:It could be hammered into elaborate, thin sheets.
  • Weight:Copper is lighter than stone or bronze, making it easier to ship 350 individual pieces across the Atlantic.
  • Durability:It was strong enough to survive a 27-day ocean voyage and the harsh winds of the harbor.

When she was unveiled on October 28, 1886, her skin—made of 300 copper sheets roughly the thickness of two pennies—shone with a bright, metallic brown luster. The transformation from “penny-colored” to “patina-green” wasn’t planned. Bartholdi actually expected the statue to age into a deeper, darker red. However, the unique environment of New York Harbor—a mix of salt air, moisture, and industrial pollution—triggered a process called oxidation.

The Timeline of Change:

  1. 1886–1900:The bright copper dulled into a dark, muddy brown.
  2. 1903:The first hints of a light green crust, or “patina,” began to appear.
  3. 1906:The color change was so controversial that Congress nearly stepped in. They appropriated $62,000 to paint the statue back to its original color, but the public protested, calling the idea “sacrilege.”
  4. 1910–1920:The statue was a patchy mix of brown and green until 1920, when the oxidation was complete, leaving her entirely teal.

While we now view the green color as iconic, it actually serves a vital structural purpose. The layer of verdigris (the green patina) acts as a protective shield. It seals the copper underneath, preventing the metal from further corrosion and weathering.  By the time the color fully changed, a new generation of immigrants had arrived in America seeing a green statue.
