#1 Posible caso de fraude Espero que quienes tengan conocimientos de física puedan amablemente ayudarme en un asunto del que me acabo de enterar. Se trata de un supuesto detector de drogas y armas. Con la poca información que publican en su sitio web, me parece a mi que es muy probable que se trate de una estafa (por los sinsentidos que publican). Este es el mecanismo, según ellos mismos, de su funcionamiento:

1 - What is GT200 Remote Substance Detection System?
GT200 Remote Substance Detection system is a revolutionary tool that provides you with 360° security protection. It is developed by Global Technical UK. The system has been developed to allow the search of large areas and reduce them to small locations . The GT200 allows for all types of narcotics or explosives to be searched for in one operation. Put it simply, it's Remote. Distance. Speed. Covert.
2 - Is the GT200 intended as stand-alone equipment?
The GT200 should be used as first indication only, and conventional methods should always be used to confirm the result of the lock. By definition, a 'lock' means a triangulated position. It can be used as confirmation of suspicions. The GT200 saves the search team and canine's working time for more efficient working. When the GT200 is used by a canine team, the area of search can be indicated from a greater distance than the dog can smell, so putting the dog in the right area quickly. This ensures that the dog is sent in to more specific area, thus saving it from sniffing fruitlessly in unproductive areas.
3 - How was the GT200 developed into the product as it exists today?
GT200 was developed to meet the requirement of being able to detect a specific substance remotely from a safe distance. Detection devices in existence today are limited to the detection of substances from molecules at a very close range (less than 3 meters) such as IMS Technology.
IMS technology includes equipment such as Barringer, GE Ton track and Saber type detectors seen today at most airport facilities. The limitation of this type of equipment is due to the fact that actual physical contact analysis of a substance or group of substances must be made vapor or substance level.
However, the GT200 is designed to detect these same substances without having physical contact with the actual substance. By doing so, it is able to detect programmed substances at very long range safely, quickly and covertly. Building upon years of field testing and trials, the GT200 went through various hardware and software revisions into the unit that exists today.
Its target market is; Law Enforcement, Military Agencies, and the corporate entities that need the ability to safely identify the possible existence of a substance and identify the parameters of the area where that substance exists. Building searches, Road blocks, Airport Cargo Containers, building entry points, car parks, etc. are all areas for which the GT200 can be deployed effectively.
4 - How does the GT200 work?
The GT200 works on the principal of dia/para magnetism. All substances carry a magnetic charge that, when stimulated by an impulse of electricity, (static) creates an attraction between the substance being detected and the GT200 unit itself. This is called EMA or Electro Magnetic Attraction.
The simple way to explain this technology is to take an inflated balloon and rub it on your hair. A static charge is being created making that balloon "attract" it to say, a wall. Provided that there is enough charge on that balloon, it will remain "attracted" to the wall for an indefinite amount of time. However, once the "charge" has dissipated, the balloon will then "unattached" between itself and fall to the ground.
What the GT200 is doing is creating an "attraction" between itself and the substance it wants to detect. Through the Substance Sensor Card and the movement of an operator, an attracting field is created in the card reader that, in turn causes the Receiver"s antenna of the GT200 to “lock onto†a signal, indicating the direction in which the substance can be located. When the magnetic signal of the substance that the GT200 is searching for, is located within its detection range, the GT200 receiving antenna will move toward the direction that the substance exist. In essence the GT200 functions like a hyper sensitive receiver.

) y por el tamaño del aparatejo no veo de donde podria sacar el potencial para lo que dicen hacer, o lleva una bateria atomica en bolsillo o acaban de encontrar un dispositivo de energia Punto-Zero
