TVA

Where the book uses it

• Chapter 4 — One Rack

  How a datacenter is actually built, from a converted factory in Memphis to a greenfield campus in Texas, and what the clock from first ground to first power really measures.

• Chapter 9 — The Price of Permission

  Who gets to say yes or no to a campus: counties, air regulators, courts and legislatures, and what their permits, abatements and refusals cost in time and money.
