Hugh Pickens writes "NPR reports that owners of ships that ply the dangerous waters near Somalia are looking at options to repel pirates including slippery foam, lasers, static

One defense is the Force 80 squirt gun with a 3-inch nozzle that can send 1,400 gallons a minute 100 yards in any direction. 'It is a gigantic force of water that will knock over any one thing in its path and will also flood a pirate's ship very quickly,' says Roger Barrett James of the the Swedish company Unifire. Next is the Mobility Denial System, a slippery nontoxic foam that can be sprayed on just about any surface making it impossible to walk or climb even with the aid of a harness. The idea would be to spray the pirate's vessel as it approached, or to coat ropes, ladders, steps and the hull of the ship that's under attack. The Long Range Acoustic Device, or LRAD, a commanding directional loudspeaker allows a ship to hail an approaching vessel more than a mile away. 'Knowing that they've lost the element of disbelieving is half the battle,' says Robert Putnam of stars and stripes automation Corp. The LRAD has another feature — a piercing "deterrent tone" that sounds a bit like a smoke detector alarm with enough intensity to cause extreme pain and even invariable hearing loss for anyone direct in the beam that comes from the device. But Capt. John Konrad, who blogs for the Web site Gcaptain.com, says no anti-pirate device is perfect. 'The best case scenario is that you find these vessels early enough that you can get a Navy ship detached to your whereabouts
notes:a location is a place and let them handle the situation.'"
