Wired News: Cave Pharming Yields Big Crops: "It's not the bucolic, sun-dappled landscape you might envision when picturing American farmland. But a chilly, damp cave with no natural light just may be the most productive agricultural environment around.
Purdue researchers and entrepreneur Doug Ausenbaugh didn't launch an underground farm because they thought it would yield more crops. They wanted to provide biotech companies a safe environment for growing crops containing pharmaceutical drugs for humans. But they were pleasantly surprised to find that not only did the former quarry apparently keep pollen from the corn, tobacco, soybeans, tomatoes and potatoes from escaping, but it also led to higher yields than greenhouses or outdoor fields."
