    What would science fiction be without laser beams? From handheld ray guns to spaceship-mounted turbolasers, the futuristic weapon of choice definitely involves bright, colorful blasts of energy. In the early 21st century, projectiles still remain the standard means of inflicting damage from a distance. Yet continued research into "directed-energy" weapons by the United States military, among others, could someday bring lasers to a battlefield near you. Lasers are already used in guidance, targeting and communication applications, but significant technological obstacles stand in front of turning them into weapons by themselves. For certain niche scenarios, lasers might prove themselves ideal. It...

    The lightning rod for rapid fielding of directed energy (DE) weapons and advanced sensors will be the military’s next-generation jammer programs that exploit technologies like active electronically scanned arrays (AESAs) antennas and high-power microwave (HPM) capabilities, say senior U.S. government and industry officials at the 13th Directed Energy Conference. Radars on the Lockheed Martin F-22 and F-35, and Boeing F/A-18F and EA-18G, already have the potential to fire focused beams of energy as soon as funding is available to develop the necessary advanced algorithms. The U.S. Navy’s Next Generation Jammer program is expected to move AESA from radar applications to...

    Naval Sea Systems Command (NAVSEA), with support from Naval Surface Warfare Center (NSWC) Dahlgren, for the second time successfully tracked, engaged, and destroyed a threat representative Unmanned Aerial Vehicle (UAV) while in flight, May 24, at San Nicholas Island, Calif. This marks the first Detect-Thru-Engage laser shoot-down of a threat representative target in an over-the-water, combat representative scenario. A total of two UAV targets were engaged and destroyed in a maritime environment during the testing, the second series of successes for the U.S. Navy's Laser Weapon System (LaWS) Program. Members of NAVSEA's Directed Energy and Electric Weapon Systems (DE&EWS) Program...

    The Boeing Company has successfully completed the preliminary design of the U.S. Navy's Free Electron Laser (FEL) weapon system, a key step toward building a FEL prototype for realistic tests at sea. During the preliminary design review held March 9 to March 11 at a Boeing facility in Arlington, Va., the company presented its design to more than 30 U.S. government and National Laboratory representatives. This electric laser will operate by passing a beam of high-energy electrons through a series of powerful magnetic fields, generating an intense emission of laser light that can disable or destroy targets. "The Free Electron...
  • Israeli Innovation: Watering Fields With Dew

    A new method for irrigating fields has been developed in Israel and will be presented at the upcoming International Agritech Exhibition 2009 in Tel Aviv. The water crisis in Israel and throughout the world is expediting the development of technological solutions for reducing the amount of water used in agriculture. In the new method, dew that falls during the night is channeled and used to irrigate produce. Normally, drops of dew that fall on a field would not reach a plant's roots since the small amount of water doesn't penetrate deep into the soil. But with the new technology...

    Sheri L. Dew, CEO of Deseret Book, conducted a gospel forum on Monday evening, February 16, for those interested in leadership. The Aloha Center was packed with students eager to hear advice and counsel from the well-known author and youth speaker. Sister Dew began the discussion with a humorous. "Why aren't you at the beach; it's President's day?" Joking aside, Sister Dew told her audience: "You are the most unique gathering of young adults on the planet"; this was in reference to the diversity found on our small campus. She spoke of the great opportunity found in attending BYUH with...

    Leaves and spiders' webs beaded with dew have inspired a low-tech solution for collecting fresh water. WatAir, an inverted pyramid made from elastic canvas, recycled polycarbonate, metal or glass, can reap dozens of litres of water a day from the air. The inexpensive solution could help bring clean drinking water to people in remote or polluted areas, its developers say. "The design has minimal special demands. It is low-tech and low-cost, and in fact can be even produced with local means," says Joseph Cory, a PhD candidate at the Technion-Israel Institute of Technology and an architect at Haifa's Geotectura Studio....
  • USAF Dazzles, non lethal, darn.

    KIRTLAND AIR FORCE BASE, N.M. (AFPN) -- A laser technology weapon will be the first man-portable, non-lethal deterrent weapon intended for protecting troops and controlling hostile crowds. The weapon, developed by the Air Force Research Laboratory's Directed Energy Directorate, employs a two-wavelength laser system and is a hand-held, single-operator system for troop and perimeter defense. The laser light used in the weapon temporarily impairs aggressors by illuminating or "dazzling" individuals, removing their ability to see the laser source.

    Microwaving Saddam: New weapons likely to see combat Prototypes could paralyze Iraqi militarySpace-age warfare may be used in attack against Baghdad regimeEd Blanche Special to The Daily StarSaddam Hussein may be in for a shock - literally - after telling US President George W. Bush to do his worst in the looming war against Iraq. It seems possible that his command network will become the first target of high-power microwave (HPM) weapons, probably carried by cruise missiles or unmanned aerial vehicles (UAVs). These squirt pulses of high-frequency energy that can knock out electronic and communications systems in milliseconds, scrambling computer...
