London, September 15 : Google is all set to extend its domination over cyberspace to the high seas, with the launch of its own "computer navy" – a set of supercomputers necessary to operate its internet search engines on barges anchored up to seven miles (11km) offshore.

According to a report in the Times, the "water-based data centres" would use wave energy to power and cool their computers, reducing Google''s costs.

Their offshore status would also mean the company would no longer have to pay property taxes on its data centres, which are sited across the world, including in Britain.

Such problems usually occur when Internet users download P2P content that is stored a long way from their homes, and the online links over thousands of kilometres get tied up delivering it.

The researchers say that their scheme called Proactive Provider Participation for P2P (P4P) can help ease the load.
