Question 1: The San Diablo dam has electricity generating turbines on a chute that connects lower and upper reservoirs. During the day, water is drained from the upper reservoir to the lower to produce electricity. But at night, electricity is used to pump the water back up to the upper reservoir. Since the water is just going back and forth, how can wealth be generated?
Question 2: Congress has passed laws requiring that a certain percentage of retail gasoline be from ethanol produced from corn. How would this destroy wealth?
