A mariner needs to lasso and tow a 125-million-ton iceberg from Antarctica to resolve South Africa's water disaster
- Cape City, South Africa, is rising from a water disaster that threatened to depart the town with out recent consuming water.
- One mariner, Nicholas Sloane, has an formidable plan to present Cape City a brand new water supply: He needs to tow an iceberg from the Antarctic and soften it.
- Sloane instructed Bloomberg Businessweek that the iceberg can be three,281 ft lengthy and get dragged to South African waters on a 90-day journey.
- The concept of towing an iceberg to make use of for consuming water has been advised earlier than as an answer to water shortages within the Center East, but it surely has by no means been performed.

A South African mariner is pushing for an uncommon resolution to Cape City’s water scarcity: kidnapping an Antarctic iceberg.
Nicholas Sloane, a 56-year-old sailor who helps rescue stranded ships, needs to make use of supertankers to lasso a chunk of floating ice in Antarctica and tow all of it the way in which to Cape City, based on Bloomberg Businessweek.
The perfect iceberg, he mentioned, would measure three,281 ft lengthy, 1,640 ft huge, and 820 ft deep. It will weigh 125 million tons — sufficient to “provide about 20% of Cape City’s water wants for a 12 months,” Sloane instructed Bloomberg.
His proposal is to tug the captive iceberg greater than 1,600 miles — a journey that may take between 80 and 90 days.
“In the event you’d requested me 10 years in the past, I in all probability would have mentioned this was loopy, however now the time is true,” Sloane instructed Bloomberg.
Water-use quotas are nonetheless in place in Cape City
Sloane has fought armed pirates, salvaged a capsizing cruise ship, and rescued penguins drenched in gas from a shipwreck, Bloomberg reported. However throughout Cape City’s crippling water scarcity, which began in 2015 and ended final 12 months, Sloane mentioned his household struggled.
Final 12 months, drought circumstances in Cape City obtained so extreme that the town frightened it will run out of municipal water completely. Throughout that point, every family was allowed a day by day quota of 13 gallons of water per particular person for requirements like washing, showering, and consuming. That is lower than one-quarter of the the typical American’s day by day water consumption.
“That is sufficient to fill lower than half a bathtub,” Sloane instructed Bloomberg. “My spouse used to take a shower each evening a bathe each morning. She instructed me, ‘You’d higher do one thing.'”
Ultimately, Cape City’s water shops weren’t fully emptied, due to heavy rainfall and strict water-use restrictions. However residents like Sloane’s household nonetheless face water quotas: Now they get a barely greater 18 gallons of recent water per particular person per day.
For a lot of South Africans, that is not sufficient to return to normal-feeling life — and that is the place Sloane’s icy caper comes into play.
Sloane will tow the iceberg with a 2-mile-wide internet
Sloane has recruited a workforce of glaciologists, oceanographers, and engineers to assist him make his iceberg-towing imaginative and prescient a actuality. He is calling the initiative the Southern Ice Venture.
The workforce’s first step can be to make use of satellite tv for pc information to discover a berg of the specified form and measurement. As soon as an appropriate iceberg is chosen, Sloane needs to ensconce it in a large internet, which might be about 2 miles huge and 60 ft excessive. The web would value about $25 million and be made out of naturally buoyant ropes that would resist chilly temperatures and excessive friction, Bloomberg reported.
This large internet would get wrapped round the 125-million-ton iceberg iceberg like a belt. Then Sloane would use two supertankers to tug the berg via uneven seas with winds reaching 80 miles per hour.
By the point the supertankers made it to Cape City, the iceberg would have shrunk by about eight%. In fact, there is not any assure that the berg would not break up and float away in some unspecified time in the future throughout the journey.
If all had been to go effectively, although, the iceberg would get moored off Cape City’s coast utilizing an 800-ton, $22-million skirt. (This could envelop the berg’s base to guard it from salt-water erosion within the Atlantic.) Then machines would harvest semi-melted glacier water and transport it to land, the place it will get fed into the municipal water system.
Sloane mentioned the iceberg may contribute to the town’s water provide for a 12 months earlier than breaking down.
In complete, the venture is estimated to value $200 million, and Sloane has secured funding from two South African banks and a Swiss water-tech firm. He has additionally contributed greater than $100,000 of his personal cash to the venture.
However Tad Pfeffer, a glaciologist, instructed Dwell Science that the worth tag means “economically, it is in all probability not all that good an concept, besides in dire emergency.”
An practically countless supply of recent water
The Antarctic Ice Sheet extends virtually 5.four million sq. miles — concerning the space of the contiguous United States and Mexico mixed. The Antarctic and Greenland Ice Sheets mixed include greater than 99% of the world’s recent water.
Yearly, greater than 100,000 Antarctic icebergs slough off the ice sheet and soften into the ocean. These bergs are sometimes a whole bunch of instances greater than their Arctic counterparts, and have steep sides and a flat high, very like a tabletop. That makes them extra steady and simpler to tow, comparatively talking.
Worldwide, 2.1 billion individuals lack entry to secure consuming water, based on the World Well being Group. So buyers and innovators see icebergs as a possible supply of recent water that may be harnessed.
Actually, Sloane’s venture will not be the primary of its form. In 2018, an engineering agency within the United Arab Emirates proposed an identical iceberg-towing initiative for Dubai. That enterprise has but to get underway, however private buyers have put $60 million behind the venture, based on NBC.

“I promise you, the water scenario in some elements of Africa is getting worse on a regular basis. It is actually not getting higher,” Sloane instructed Bloomberg, including, “20 or 30 years from now, I feel towing icebergs shall be an everyday factor.”
