On the coast, rigs that troops call "HESCO barriers" now stand in shallow water off Dauphin Island in a 3-mile-long wall meant to stop oil from fouling delicate grasses and bird habitat. They are filled with sand to help catch the oil and hold the rigs in place, and plans call for adding an absorbent agent to solidify the petroleum once it's captured. "We never really thought about them being used this way, but hopefully it will help," said Dennis Barkemeyer, a technical representative from HESCO Bastion. Alabama National Guard troops who built the wall don't know whether the contraptions will work. "There's people getting paid a lot more money than me to think up and dream up these things. We're just here executing the mission," said Sgt. Maj. William Jones. Another old idea is being used in a new way on the island, a narrow coastal barrier between the Gulf and Mississippi Sound. Bulldozers and bucket-loaders have pushed sand into a long ridge along the main road in an attempt to prevent oil from flowing across streets and into sewers should the slick hit Dauphin Island. In the past, such berms were constructed to guard against hurricanes. BP's leading solution for stopping the underwater oil gyser has an otherworldly quality itself: Crews built a 100-ton concrete-and-metal box that's supposed to be placed over one of the leaks to capture oil that's now flowing into the Gulf. BP says the contraption will be on the seabed by Thursday.
Homespun remedies have been proposed and used in past oil spills with mixed results. In 2006, when oil gushing from a sunken tanker threatened beaches, coral reefs and swamps in the Philippines, the government initially bought into the idea of using human hair clippings to mop up oil. Hair and feathers were gathered at collection centers, but officials decided against distributing them to coastal villages for fear of causing more pollution. Instead, rice stalks were attached to bamboo poles and used as makeshift brooms that successfully sopped up oil from the water near the coast, said Teresita Siazon, the coordinator of the civil defense council in the Guimaras province. Rice brooms might make it to the Gulf of Mexico before anyone tries to cap the well with a huge wine stopper. "I'm not aware that a cork has been tried," said Lt. Collin Bronson, a Coast Guard spokesman.
