” The wreck of a Nazi submarine sunk during World War II has been found off the coast of North Carolina, maritime authorities announced Tuesday.
U-boat 576 was found just 240 yards from another wreck: the American freight ship, Bluefields, which it torpedoed in the Battle of the Atlantic in 1942.
The twin wrecks were found just 30 miles off the North Carolina coast, the National Oceanic and Atmosphere Administration said.
” Most people associate the Battle of the Atlantic with the cold, icy waters of the North Atlantic,” said David Alberg at the NOAA. “But few people realize how close the war actually came to America’s shores.” “
“… how close the war actually came to American shores.” is an understatement as the fact is German spies were actually put ashore on the beach in sleepy Amagansett , New York from a sister U-Boat on the night of June 12/13 1942 …
” Shortly after midnight on June 13th, four trained German saboteurs landed on the beach near the Coast Guard Station at Amagansett, Long Island. They had made the voyage across the Atlantic in a German submarine and had rowed ashore in a collapsible rubber boat containing clothing, explosives, and several thousand dollars in cash. On June 17th, four other saboteurs were similarly landed from a submarine at Ponte Vedra Beach, south of Jacksonville, Florida. On June 27th, J. Edgar Hoover announced the arrest of all eight saboteurs and the discovery of maps and plans for a two year program designed to destroy war plants, railways, water works and bridges in the United States.”

” The future of war is a laser-guided bullet that can change direction and hit targets at a distance of over one mile away.
DARPA, the research arm of the Pentagon, has developed the EXACTO system to put a four-inch-long bullet with an optical laser sensor and an eight-bit central processing unit that can compute an algorithm to command electromagnetic steering to give the bullet its deadly precision.
Unlike most rifle bullets, EXACTO has no spin. Instead, it travels like an electronic dart with fins that can guide it in mid-air.
A sniper team can control the bullet after firing to ensure accuracy while compensating for weather, wind, target movement, and a range of other factors.”
” As a pilotless F-16 roared into the sky Sept. 19 at Tyndall Air Force Base, Fla., members of Boeing’s QF-16 team and the U.S. Air Force celebrated.
The flight represented the first unmanned QF-16 Full Scale Aerial Target flight. Put another way, fighter pilots now have an adversary for which to train against that prepares them like never before.
Two U.S. Air Force test pilots in a ground control station at Tydall remotely flew the QF-16, which is a retired F-16 jet modified to be an aerial target. While in the air, the QF-16 mission included a series of simulated maneuvers, reaching supersonic speeds, returning to base and landing, all without a pilot in the cockpit.
“ It was a little different to see it without anyone in it, but it was a great flight all the way around,” said U.S. Air Force Lt. Col. Ryan Inman, Commander, 82nd Aerial Targets Squadron. “It’s a replication of current, real world situations and aircraft platforms they can shoot as a target. Now we have a 9G capable, highly sustainable aerial target.”
Prior to the QF-16, the military used a QF-4 aircraft, which was a modification of the F-4 Phantom, a Vietnam-era fighter The modified QF-16 provides pilots a target that performs closer to many jets flying today.
The QF-16s were all retired aircraft. Boeing retrieved them from Davis Monthan Air Force Base in Arizona and restored them for flight.
Next up, live fire testing moves to Holloman Air Force Base, N.M. The military will ultimately use QF-16s for weapons testing and other aerial training.
So far, Boeing has modified six F-16s into the QF-16 configuration.

” Disposable and rechargeable batteries that power tens of millions of portable electronics could become obsolete over the coming decades as new technologies come to market that can convert ambient energy into usable electric power, new research shows.
The concept, known as “energy harvesting” (EH), is becoming more viable as technology firms bring products to market that can transform electromagnetic, thermal and mechanical energy sources into power that can be stored and used.
“In the near future, EH technology will power an increasing number of consumer and industrial products that are untethered or need to become disconnected from electrical outlets,” researchers with Navigant Energy said in a recent published report on the technology. Moreover, EH systems “offer an inexpensive and compact way to power portable electrical devices that in many cases rely heavily on batteries.” ”
” “A coilgun is a linear motor. Electronics hobbyist James Paul has developed a great mathematical model of a basic linear motor on his website Coilgun Systems. Please read about his model here. A key conclusion drawn from the model is that coils become more efficient as projectile speed increases. This conclusion rules out a single-stage coilgun as a good design because full power is dumped up front when the projectile is still moving slowly. A much better design uses multiple, lower power coils to distribute the acceleration over a longer distance so less energy is wasted during the initial slower portion of the acceleration. As the projectile speeds up, subsequent coils become increasingly efficient so adding more coils and lengthening the gun improves efficiency and increases muzzle energy. That means an efficient, powerful coilgun will be long and have as many stages as possible.”
” Revellers at a South African outdoor rock festival no longer need to queue to slake their thirst — a flying robot will drop them beer by parachute.
After clients place an order using a smartphone app, a drone zooms 15 metres (50 feet) above the heads of the festival-goers to make the delivery.
“Every time it drops a parachute a crowd of 5,000 cheers,” he said.”
” Being strapped to a water propelled jetpack and launching nine meters into the air can be one of the best adrenaline rushes a person can get. But to others it sparks a couple of concerns.”

” The world’s GPS system is vulnerable to hackers or terrorists who could use it to hijack ships — even commercial airliners, according to a frightening new study that exposes a huge potential hole in national security.
Using a laptop, a small antenna and an electronic GPS “spoofer” built for $3,000, GPS expert Todd Humphreys and his team at the University of Texas took control of the sophisticated navigation system aboard an $80 million, 210-foot super-yacht in the Mediterranean Sea.”
Hacker Found Dead Just Days Before He Was Due To Demonstrate How To Kill Someone Fitted With A Pacemaker At Conference
” Mystery surrounds the death of a celebrated computer hacker who claimed to know how to remotely kill someone fitted with a heart pacemaker – as happened in the fictional TV spy drama Homeland.
Barnaby Jack died in San Francisco on Thursday, just days before he was due to give a speech revealing how implanted heart devices were at risk from fatal hacking attacks.
The San Francisco Medical Examiner’s office confirmed the death last night but did not give any further details.”

” Odyssey Marine Exploration Inc. recovered 61 tons of silver this month from the SS Gairsoppa, a World War II shipwreck lodged nearly three miles below the surface of the Atlantic Ocean off the coast of Ireland.
Odyssey recovered 1,574 silver ingots weighing a total of about 1.8 million ounces from the SS Gairsoppa, the Tampa, Florida-based deep-sea salvage company said in a statement Monday. The 412-foot (126-meter) British cargo ship was torpedoed by a German U-boat in February 1941, according to Bloomberg.
The metal was worth about $630,000 when the Gairsoppa was sunk and about $36 million at today’s prices. Odyssey has recovered a total of 2,792 ingots from the wreck, about 99 percent of the insured silver reported to be aboard when the vessel sank.”
