[16][17]. [14] An Air Force report called them "hypervelocity rod bundles". $49.99 Okuma SST Casting Rods. The highly elongated shape and high mass of the projectiles are intended to enhance sectional density (and therefore minimize kinetic energy loss due to air friction) and maximize penetration of hard or buried targets. A smaller "crowbar" variant is mentioned in David's Sling by Marc Stiegler (Baen, 1988). [12], The weapon would be very hard to defend against. Please make sure that you are posting in the form of a question. The larger device is expected to be quite effective at penetrating deeply buried bunkers and other command and control targets. Specification : Color: yellow and green LED light color: blue With twin bells bite alarm Great for professional and occasional fishermen Ensure fishing line is able to be seen in the dark night Powered by 2 LR41 button batteries How To Use: 1. With 6–8 satellites on a given orbit, a target could be hit within 12–15 minutes from any given time, less than half the time taken by an ICBM and without the launch warning. [10] These designs are envisioned as a bunker buster. Any infrared launch signature occurs in orbit, at no fixed position. Reverse the Batteries 2. The Lightning Strike Fire Starters are billed as the world's best survival fire starter. Unable to add item to List. The weapon reportedly weighed 100 pounds and contained 6 deployed blades to destroy the passenger vehicle that was targeted. If electric insulation fails in some part of a system or electric device, the electric ground will allow current to be dissipated into the earth instead of electrifying the structure or the device itself. The concept originated during the Cold War.. The term can also sometimes be used to refer to a similar type of grounding apparatus called a halo ring ground which is a ring of wire suspended from the ceiling of a room for the purpose of serving as a connection point for ground wires for electrical equipment or devices. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. Equipment buildings and other structures with sensitive equipment, such as computer depots and data banks, are often protected by ring grounds as well. The infrared launch signature also has a much smaller magnitude compared to a ballistic missile launch. A kinetic bombardment or a kinetic orbital strike is the hypothetical act of attacking a planetary surface with an inert projectile from orbit, where the destructive power comes from the kinetic energy of the projectile impacting at very high speeds. In the case of the system mentioned in the 2003 Air Force report above, a 6.1 m × 0.3 m tungsten cylinder impacting at Mach 10 has a kinetic energy equivalent to approximately 11.5 tons of TNT (or 7.2 tons of dynamite). $84.99 - $89.99 Lamiglas Classic Glass Series Casting Rods. [15] During the Korean and Vietnam Wars, there was limited use of the Lazy Dog bomb, a kinetic projectile shaped like a conventional bomb but only about 25.4 mm (1") long and 9.525 mm (3/8") diameter. The system would also have to cope with atmospheric heating from re-entry, which could melt non-tungsten components of the weapon. The wire must be buried at least 2.5 feet (75 cm) underground and outside the dripline to help reduce corrosion. Typical depictions of the tactic are of a satellite containing a magazine of tungsten rods and a directional thrust system. Twist Lights Lid Off 2. These lures are available in a plethora of sizes, shapes, colors, hook styles, and blade finishes. [9][11] As the name suggests, the 'bunker buster' is powerful enough to destroy a nuclear bunker. Copper-bonded ground rods are coated with copper to a thickness of 10 mils or .010 inches. There would be no need to deploy missiles, aircraft or other vehicles. $89.99 Okuma Cedros "A" Salmon, Halibut & Sturgeon Rods… In most developed parts of the world, electric grounds are required for power delivery systems in all buildings, including residences. The standard size wire for a ring ground is a number 2 gauge copper wire, which is a heavy gauge wire. In addition, projectiles would not require explosive warheads, and—in the simplest designs—would consist entirely of solid metal rods, giving rise to the common nickname "rods from God". Grounding of electrical systems is an important technique for reducing risk of electric shock or damage due to lightning strikes. Jerry Pournelle created the concept while working in operations research at Boeing in the 1950s before becoming a science-fiction writer. Today I'm putting that to the test. Most predominantly featured in Halo Wars and Halo Wars 2, the MAC is an ability that allows the player to utilize the UNSC Spirit of Fire's point-defense MAC for pinpoint orbital bombardment, allowing the player to heavily damage or destroy enemy units. Find answers in product info, Q&As, reviews. Essentially large coilguns, MACs are capable of firing a variety of ammunition types varying on the model and bore, ranging from hyper-dense kinetic kill slugs to sub-caliubar rounds to semi-autonomous drone missiles[20]. Ring grounds are often used in combination with lightning rods to dissipate the electricity from a lightning strike. The main difference between the two rods is the thickness and type of material used to cover the steel core. Hypothetical weapon of mass destruction via orbital strikes of projectiles with incredible kinetic energy, "Project Thor" redirects here. A ring ground can also be part of a lightning protection system and is used for dissipating electricity from direct lightning strikes on lightning rods, which are connected to the ring ground by heavy gauge copper wire. Number 2 gauge wire is approximately 0.25 inches (6.54 mm) thick. Shakespeare Ugly Stik Elite Salmon/Steelhead Casting Rods. In the mid-1960s, popular science interest in orbital mechanics led to a number of science fiction stories which explored their implications. These were dumped from aircraft onto enemy troops and had the same effect as a machine gun fired vertically. [7] The mass of such a cylinder is itself greater than 9 tons, so the practical applications of such a system are limited to those situations where its other characteristics provide a clear and decisive advantage—a conventional bomb/warhead of similar weight to the tungsten rod, delivered by conventional means, provides similar destructive capability and is far more practical and cost-effective. Project Thor is an idea for a weapons system that launches telephone pole-sized kinetic projectiles made from tungsten from Earth's orbit to damage targets on the ground. Ground Rod Basics (Service panel) • Second ground rod.A single ground rod that has a resistance to ground of 25 ohms or less must be augmented by a second ground rod. Please try again. It may be solid or made up of strands, and will encircle the entire structure around which it is installed. It floats very well and is available in a myriad of colors. It also gets high marks for not hinging your leader and its … [2], In June 2020, a senior Al Qaeda leader was killed by a kinetic weapon (a modified AGM-114 Hellfire missile) dropped by a United States Special Operations General Atomics MQ-1 Predator drone. Kinetic bombardment has the advantage of being able to deliver projectiles from a very high angle at a very high speed, making them extremely difficult to defend against. Halo features the Magnetic Accelerator Cannon (MAC), or Mass Accelerator Cannon, as the primary weapon system employed by the United Nations Space Command (UNSC) on its warships and orbital defense platforms[18][19]. Launch is difficult to detect. "The Meaning of the Ring and Rod in Babylonian-Assyrian Sculpture" is an article from The Biblical World, Volume 26. The time between deorbit and impact would only be a few minutes, and depending on the orbits and positions in the orbits, the system would have a worldwide range. A halo ring ground is sometimes found in such structures, which is connected to an outside earth ground assembly, usually a grid or series of steel or copper bars. During the 1980s and 1990s references to such weapons became a staple of science fiction roleplaying games such as Traveller, Shadowrun and Heavy Gear (the latter game naming these weapons ortillery, a portmanteau of orbital artillery), as well as visual media including Babylon 5's "mass drivers" and the film Starship Troopers, itself an adaptation of a Heinlein novel of the same name. The Fishing Bell easily clamp on to your rod and ring when fish strike Red Light Color A perfect accessory for your fishing rod Water resistant, so can be used in rai Length: 75mm/3"; Width: 26mm/1"; Bell diameter: 16mm/0.6" In Neal Stephenson's Anathem, a kinetic bombardment weapon is deployed from orbit to trigger the eruption of a dormant volcano. A piece of sheet metal was folded to make the fins and welded to the rear of the projectile. Another foam option is the “Turn On Strike Indicator,” two molded-foam pieces that cleverly attach together on your leader using a mini dog-bone shaped rubber band. $109.00 Shimano Clarus Steelhead Spinning Rods. Please try your search again later. Silicon carbide, or SiC, is usually considered the best material today. The rods would typically be shaped to minimize air resistance and maximize terminal velocity. As a practical matter, few electricians do the resistance measurement.
