 Microsoft has sunk a data centre in the sea off Orkney to investigate whether it can boost energy efficiency. 
  
 The data centre, a white cylinder containing computers, could sit on the sea floor for up to five years. 
  
 An undersea cable brings the data centre power and takes its data to the shore and the wider internet - but if the computers onboard break, they cannot be repaired. 
  
 Orkney was chosen because it is a major centre for renewable energy research. 
  
 The theory is that the cost of cooling the computers will be cut by placing them underwater. 
  
 "We think we actually get much better cooling underwater than on land," says Ben Cutler, who is in charge of what Microsoft has dubbed Project Natick. 
  
 "Additionally because there are no people, we can take all the oxygen and most of the water vapour out of the atmosphere which reduces corrosion, which is a significant problem in data centres."

 It will not be possible to repair the computers if they fail, but the hope is that there will be a lower failure rate than on land. 
  
 This is a tiny data centre compared with the giant sheds that now store so much of the world's information, just 12 racks of servers but with enough room to store five million movies. 
  
 Microsoft's first experimental underwater data centre, sunk for five months in 2015, was dubbed Leona Philpot after a character in an XBox game. 
  
 If Project Natick proves a success, Microsoft envisages sinking groups of five of these cylinders and being able to deploy a data centre offshore in 90 days, whereas it could take years on land. 
  
 The operation to sink the Orkney data centre has been an expensive multinational affair. 
  
 The cylinder was built in France by a shipbuilding company, Naval, loaded with its servers and then sailed from Brittany to Stromness in Orkney. There, another partner, the European Marine Energy Centre (EMEC), provided help including the undersea cable linking the centre to the shore. 
  
 The presence of EMEC, with its expertise in renewable energy and its knowledge of the seas around Orkney, was one factor behind Microsoft's decision to choose this location. 
  
 "We've got so much renewable energy here," says EMEC managing director Neil Kermode. 
  
 "We've produced more than we need since 2012." 
  
 The Orkney Islands were early adopters of wind energy. And EMEC has been experimenting with tidal and wave energy for 14 years, with one of its test sites on the beach where the Project Natick cable comes ashore. 
  
 There has been growing concern that the rapid expansion of the data centre industry could mean an explosion in energy use. 
  
 But Emma Fryer, who represents the sector at Tech UK, says that fear has been exaggerated. 
  
 "What's happened is we've had the benefit of Moore's Law," she says. 
  
 The continued advances in processing power have made doom-laden predictions look foolish, Ms Fryer says. 
  
 "We've been able to deal with explosions of data with only a small increase in the energy used." 
  
 Nevertheless, she accepts there is a challenge as the industry continues to expand and she welcomes experiments such as Microsoft's. 
  
 "It's really exciting that they are thinking this radically," she says. 
  
 Ms Fryer also thinks situating data centres near to or under the sea is a good idea. 
  
 She says: "50% of the world's population live near the coast."

 Another expert is not so sure. 
  
 Prof Ian Bitterlin, a data centre consultant for nearly 30 years, is sceptical about the environmental impact of going underwater. 
  
 "You just end up with a warmer sea and bigger fish," he says. 
  
 And 90% of Europe's data centres are in big cities such as London and Madrid because that is where they are needed. 
  
 Microsoft's Ben Cutler insists the warming effect will be minimal - "the water just metres downstream would get a few thousandths of a degree warmer at most" - and the overall environmental impact of the Orkney data centre will be positive. 
  
 As we bobbed about on a boat just above the site where the data centre was to be sunk the following day, I put it to him that many people might think the whole venture was a bit crazy. 
  
 "This is a crazy experiment that I hope will turn into reality" he said. "But this is a research project right now - and one reason we do different types of research into data centres is to learn what makes sense before we decide to take it to a larger scale." 
  
 Now, the Project Natick team will monitor the data centre for the next five years. It could turn out to be a signpost to the future - or maybe just a tourist attraction for passing fish. ||||| Microsoft is leveraging technology from submarines and working with pioneers in marine energy for the second phase of its moonshot to develop self-sufficient underwater datacenters that can deliver lightning-quick cloud services to coastal cities. An experimental, shipping-container-size prototype is processing workloads on the seafloor near Scotland’s Orkney Islands, Microsoft announced today. 
  
 The deployment of the Northern Isles datacenter at the European Marine Energy Centre marks a milestone in Microsoft’s Project Natick, a years-long research effort to investigate manufacturing and operating environmentally sustainable, prepackaged datacenter units that can be ordered to size, rapidly deployed and left to operate lights out on the seafloor for years. 
  
 “That is kind of a crazy set of demands to make,” said Peter Lee, corporate vice president of Microsoft AI and Research, who leads the New Experiences and Technologies, or NExT, group. “Natick is trying to get there.” 
  
 Lee’s group pursues what Microsoft CEO Satya Nadella has called “relevant moonshots” with the potential to transform the core of Microsoft’s business and the computer technology industry. Project Natick is an out-of-the-box idea to accommodate exponential growth in demand for cloud computing infrastructure near population centers. 
  
 More than half of the world’s population lives within about 120 miles of the coast. By putting datacenters in bodies of water near coastal cities, data would have a short distance to travel to reach coastal communities, leading to fast and smooth web surfing, video streaming and game playing as well as authentic experiences for AI-driven technologies. 
  
 “For true delivery of AI, we are really cloud dependent today,” said Lee. “If we can be within one internet hop of everyone, then it not only benefits our products, but also the products our customers serve.” |||||
Output:
Microsoft has just launched something big. Literally. It has placed a datacenter—a facility that houses connected servers—off the Orkney Islands, near the northeastern coast of Scotland, reports Yahoo. A datacenter collects, processes, and stores large amounts of data, and Microsoft’s underwater center will perform the same functions as a traditional center but in a submarine-like capsule. It will be unmanned, so if something fails onboard, it cannot be repaired. An undersea cable attached to the capsule will deliver the data to the wider internet. The idea behind placing the center underwater is that datacenters use a huge amount of electricity, run very hot, and require massive amounts of cooling—and the seawater provides instant cooling. In addition, the center plans to capture energy generated by the movement of waves. According to Microsoft, the center, which will be deployed for five years, is 40 feet long and is loaded with 12 racks containing 864 servers and 27.6 petabytes of storage—enough to store five million movies. One consultant is concerned about the potential environmental impact. "You just end up with a warmer sea and bigger fish," he tells the BBC. And the location may not be as ideal as it seems, given that most of Europe’s datacenters are located in large cities because that’s where the greatest demand is. This is the second phase of what Microsoft is calling Project Natick. Phase one involved placing a similar but smaller vessel off the coast of California.
