The Dubai Iceberg

A case of satirical prophecy in the news.

Back on April 1, 1978, prankster Dick Smith towed a foam-covered barge into Sydney harbor, claiming it was an iceberg he had towed from Antarctica. Of course, it was an April Fool's Day joke.

But now a Dubai-based engineering firm claims they really want to tow a 100-million-ton iceberg from Antarctica to Dubai. They figure that even if 30% of it melts by the time it gets to the Persian Gulf, that'll still be a whole lot of fresh, frozen water.

But what are they going to do with it once it gets there? How would they stop it from melting into the ocean before they could get it onto land and use it?

Not to worry. The environmental crazies will get 'em.

This has been covered in sci-fi ... tug it into a prepared bay, build a dike across the entrance, and pump the saltwater out. Of course, that kills all the saltwater life in the bay... so maybe an estuary? Maybe even dig a cove for it. It'll all depend on how thirsty everyone is.

I did some rough math. One cubic meter of ice is about one ton. A flat ice sheet of maybe ten meters depth would be more practical. This can be shaped to reduce drag and icebergs do flip. 100,000,000 /10 still would having you towing an ice island two K x five K.

Wouldn't it be cheaper to by a bottling plant near a south american port, melt the iceburg into the bottles, then ship the bottles to dubai?

Canada did have a plan to ship vats of water from its lakes to Dubai. However, even taking into account that it's cheaper than thawing an and bottling it, since the Saint Lawrence gulf is closed to Dubai than any South American city and that lake water doesn't need melting, it was still cheaper to pump water from the Persian Gulf and remove the salt by inverse osmosis. Furthermore, nobody wanted to drink water that came from petrol tankers.

Plastic/rubber sheet can be made to any length -- just set up a line of extruders with machines between to lap and seal the sheets together to the desired width, slide it under the iceberg, float the edges, pump out the saltwater.

If the basic theory is ever proven possible, someone might invest in a floating dry dock large enough to accommodate an iceberg. I think the biggest so far is about a thousand feet long, but it's probably more of a money issue than a technological one to build one the required size.

Sorry, Phideaux, but this plan has been raised again and again and proven <i>not<i> feasible every single time.

@Richard Bros -- It's been proven to not be economically feasible and/or not feasible with the technology of the time. Such things change/evolve.

The biggest problem is how to tow/push an iceberg. There are several aspects which haven't been solved yet. The growing body of technology behind nuclear-powered icebreakers may help overcome some serious obstacles.
