In Response To: US PATENT: US NAVY HAS DEEP WATER ULTRASONIC (SCALAR?) WEAPON OPERATIONAL *PIC* (IZAKOVIC)
Very interesting article. I don't know if the whales were killed by the testing device but that would really upset me if that was the case.
The reason that ultrasonics can generate destructive forces through a 'scalar' interefernce of two ultrasonic beams is that water can be torn apart above a certain acoustical level. Hence having two beams, the acoustical levels of which are just below cavitation threshold, combine will produce cavitation at the intersection.
On the other hand, I don't believe that anyone has ever seen the vacuum torn apart from the intersection of 2 electromagnetic beams. People, such as Tom Bearden, claims that intersecting 2 'scalar' beams will cause energy release at the intersecting area. I have not seen it and don't believe that it happens the way Bearden describes.

United States Patent 7,206,257 from April 17, 2007 describes the use of acoustic remote caviation as open underwater target destruction device.

Abstract
A method is disclosed of generating a predetermined field of cavitation around a remote target in an underwater environment. The method includes the steps of identifying a remote target location, generating at least two acoustic beams, each at a high power output, from an underwater acoustic source, and controlling the generated acoustic beams to intersect with each other at the remote target location and thereby create a destructive cavitation field at the intersection of the beams. The acoustic source and target can be located in unconfined underwater space and at a distance of at least 100 m apart.
Description of the preferred embodiment
In general, the present invention is directed to an environmentally clean self-defense weapon, generally shown in operation in FIG. 1. The weapon 10 includes an array of selectively activated sonar devices 12, 14, 16, that will eliminate or destroy unwanted underwater objects 18 remotely without using explosive materials. It is a characteristic of the present invention that the underwater environment is that of free and open underwater space such as that found in lakes, oceans and other large bodies of water.
The underwater object 18 targeted for destruction is shown generically in FIG. 1 and may include mines, incoming torpedoes, marine fouling barnacles, and emergency rescue operations. It will be understood that the position of the underwater object 18 is not necessarily specifically identifiable, yet is within a range of about 100 meters to about 1 Km from a source vessel such as a submarine 20.
The weapon 10, including the array of sonar devices 12, 14, 16, is mounted to or formed in connection with the submarine 20 or similar underwater vehicle capable of transporting and providing power to the weapon array 10. In the subject of FIG. 1, the weapon array 10, including three sonar devices 12, 14, 16, is shown to be targeting the object 18 located a distance 22 from the submarine 20. The sonar sources 12, 14, 16 of the weapon 10 are mounted on the submarine 20 at predetermined intervals. For example, a first sonar source 12 may be mounted at the nose 30 of the submarine 20, a second sonar source 14 mounted at a mid-section 32 of the submarine 20, and a third sonar source 16 mounted at a tail 34 of the submarine 20. This array spacing and number of sonar sources is by way of example only and will be modified to suit the particular underwater transport source. Regardless of the spacing of the array 10 or number of sonar sources used, the beams 12b, 14b, 16b from the sonar sources 12, 14, and 16, respectively, will be directed to intersect at a cavitating focal point coinciding with the determined location of the target 18. The intersecting beams at the cavitating focal point of the sonar sources will create a destructive cavitation field generally identified at 24 in FIG. 1.
The sonar sources 12, 14, and 16 of the weapon 10 are activated to generate a focused beam at a frequency of 10 KHz to 15 KHz. All calculations for target 18 location, output frequencies, intersecting focal points of the sonar sources 12, 14, 16, and required signals to control "firing" of the sonar sources is by way of an on-board computer 26 connected to the sonar sources.
Any general-purpose active sonar source can be used to assemble a weapon array 10 as in the present invention. The underlying physics is based on the intense heat and high-pressure pulse from the sonar sources 12, 14, and 16 as the damage mechanisms by virtue of the intense acoustic power of the sonar sources. An ensuing cavitation bubble formation and collapse and shock propagation will also inflict damages on underwater objects 18 targeted for removal. The technical drivers are the cavitation lethality on the undesirable objects 18 and the acoustic power of the sonar sources versus range and depth.
Any sonar array can be used in this mode. The stand off distance is the focal length of the array as defined by the intersection of the separate sonar sources 12, 14, 16. A function of physical dimension of the array is that the longer the span of the array along the support member 20, the farther away the standoff or target distance may be.
Historically, an acoustic array is always designed to avoid cavitation. This invention seeks to operate the acoustic array weapon 10 at its peak power output to maximize cavitation at the focal point of the array. The key elements of the operation are: computation of the focal point location and acoustic beamforming to cover the object location.
There are several advantages to the present invention including a lack of environmentally detrimental residues that will be generated. Further, beamforming greatly reduces response time so that more objects can be removed in a given time. Also, the present invention reduces cost per object removed. This concept also enables all sonar to be used as a device to remove undesirable objects. Furthermore, without any explosives and the increased standoff distance from the device, the operating platform of the underwater vessel 20 with the sonar array 10 will not suffer any damage.

Now it is clear that all those whales did not die as accidental victims of a new sonar device. They were subject of weapon tests target practice.
What is interesting is to note that this weapon is based on interference of two or more caustic beams at, so-called, focal point, which permits only local release of heat followed by cavitation. For the same scope one would expect scalar energy weapon would be used in the same way.
