> even for smaller icebergs Naively, the energy cost of towing should go as the 2/3 power of the mass of the iceberg, whereas the energy cost of desalination is linear. So bigger is better! Of course, it's a million times bigger than the biggest iceberg ever towed, so I guess there is some technical risk. But where's your can-do attitude?
