#3: Redbox DVD rentals....and books!
The Espresso Book Machine—meaning "fast," not coffee—can churn out a 300-page paperback on demand, complete with color cover, in just 3 min. The $50,000 machine could transform libraries into minibookstores, making hard-to-find titles as accessible as cappuccinos. At $3 a book they might be cheaper too. They are available now.
