For years and years I used to tell my microeconomics students that one response to the water shortage in California caused by price controls was a proposal to use icebergs f0r fresh water. But unlike the company described in the this article as believing "they would not melt significantly during the voyage" the information I had indicated that melting was a big worry. But the engineers--practical, as always--proposed to wrap the icebergs in plastic, on site in the Antarctic.
And I told the students if you think that will be cheap, guess again. Such are the potential costs of tampering with the price system.
