Subscribe to RSSDiscovery News' David Teeghman runs through four of the relatively feasible schemes suggested to combat the Gulf oil spill. You'll find one of them, the oil-blocking water filter, discussed on TechNewsDaily as well. Another high-profile idea, actor Kevin Costner's oil-sucking whirligig, was fielded by my msnbc.com colleague Kari Huus. If you build it, will it run?

ground freezing technique using liquid nitrogen is a good idea ,i think .because the liquid nitrogen is a non-inflammable gas so we dont have any fire risk .the liquid nitrogen can freeze water at -250c.the crud oil will easily freeze and it will block the oil spill..already there is a presence of methane ice so it is easy to freeze..we have to insert cooling pipes in the surrounding mud of the bop .so the bop will freeze and it stops the oil flow
