Ok so we can't use the wind to propel the iceberg, so then can we use  
it to steer the iceberg? Apply small but constant force orthogonal to  
the current to guide the iceberg to warmer latitudes where we can use  
the temperature difference between the water and the iceberg to power  
a heat engine to propel the iceberg to the highest bidder?
