Washington (CNN) Huge inflatable plugs now being developed by the federal government to protect subway tunnels from terrorist attacks likely could have saved some of New York’s subway tunnels from storm related flooding, according to plug developers, some of whom are wistful that development wasn’t completed in time for Hurricane Sandy.
The canada goose shop uk review Department of Homeland Security successfully tested a plug in January, using the 16 foot diameter prototype to hold back pressurized water at a test tunnel in Morgantown, West Virginia. Another test to demonstrate canada goose outlet store new york the plug’s reliability is scheduled for next week. “The problem is we don’t have a canada goose finance uk stock of things that we could put in place. It’s not like we have a canada goose coats on sale bunch of these sitting in a warehouse,” Holter said. “It’s a little frustrating really that we weren’t at a better stage at this thing.”
cheap canada goose uk “We’ve proved that these plugs can hold back water,” said Dave Cadogan of ILC Dover, the plug’s manufacturer. “I wish we had moved a little bit faster as a team and had gotten this development done.” cheap canada goose uk

Ever Barbero, a West Virginia University professor who helped develop the idea, says he thought of the plug immediately when he saw a news report that New York was closing the Holland Tunnel in advance of the storm.
“I said to my wife, ‘It’s a pity that every tunnel doesn’t have two of these plugs’,” he said.

“This is an experimental prototype. This is something that is probably two canada goose bird uk years away or so” from real world applications,” Fortune said. “It canada goose black friday toronto would be like asking Apple, ‘Why can’t I have an iPhone 6 now?’ Because it’s somewhere in the lab now. It’s not ready to go.”
Canada Goose Coats On Sale The plug simple in theory, but sophisticated in design inflates like a balloon to fit the contours of a tunnel, and can reduce leakage to amounts manageable by pumps. Placed on either end of some of the tunnels under New York’s East River, the plugs could have prevented flooding, team members told CNN. But plugs would not have prevented water from infiltrating porous underground subway stations and other infrastructure, they said. Canada Goose Coats On Sale

In all, seven New York subway tunnels and two commuter train tunnels flooded during canada goose gilet uk sale Monday’s record flooding.
Canada Goose Outlet The Department of Homeland Security began the “Resilient Tunnel Project” in 2007, focusing on the threat of terrorist gas attacks and fires in transit tunnels. But almost from the start, developers believed the technology could serve a dual purpose, protecting tunnels from floods during natural disasters. Canada Goose Outlet
Sandy’s impact: State by state
DHS teamed with the Pacific Northwest National Laboratory, West Virginia University and ILC Dover, a private Delaware company, on the project.
canada goose coats An early scaled down plug, consisting of a single layer, was effective at preventing smoke or gas penetration. But when the team used a stronger, single layer plug in a full scale inflation test, the fabric failed, sending the team “back to the drawing board,” Fortune said. canada goose coats
The current plug consists of three layers, including a tough outer layer that consists of thick webbing made of Vectran, a liquid crystal polymer fiber.
The plugs must be canada goose cap uk fitted to individual tunnels.
“When you look at these things, you get the idea of a kid’s balloon,” Halter said. But “they are not at all stretchable. They are specifically made to fit a tunnel of a specific dimension. They are tailor made. Their ability to expand or contract is less than 1%.”
Victims fall to Mother Nature’s wrath

The existing test plug is roughly 32 feet by 16 feet and holds 35,000 gallons of water.
