    Miniaturized robots, also mown as micro-robots, may be used in numerous situations and locations to receive and transmit data communications and perform various other requirements. Micro-robots may be positioned in remote locations to either transmit images or sounds or other types of data. Micro-robots may be used for commercial or military applications. For instance, in a commercial application, micro-robots may be used to locate and identify personnel trapped within buildings as a result of earthquake or terrorist attack.The micro-robots are sufficiently small enough to maneuver within the collapsed structure and navigate within very small confinements. Micro-robots may use various methods for maneuvering to its destination, including but not limited to hopping, vibrating, and rolling. Micro-robots currently rely upon “button batteries” for power supplies. The operational time for which such traditional button batteries can supply power is measured in hours. Therefore, without an improved system or method for providing extended power to the micro-robots, the use of micro-robots becomes extremely limited. In order for the micro-robots to operate over a long period of time, it will be necessary for the micro-robots to be able to recharge their batteries within the environment for which they are located. For example, within a collapsed structure, the only source of reliable power is heat. Optimally, a number of potential heat sources should be available to ensure rapid location of such power supplies.

  • Aluminized eutectic bonded insensitive high explosive

    United States 5,411,615
    Issued

    An insensitive high explosive is obtained by using a dicyandiamide (DCDA), ammonium nitrate (AN), guanidine nitrate (GN), ethylene diamine dinitrate (EDDN) eutectic melt binder in combination with ammonium perchlorate (AP) oxidizer, fine RDX (1 .mu.m to 10 .mu.m particle size), and aluminum metal as a fuel. The fine RDX particles improve performance, boosterability, and sensitivity. The inclusion of AP greatly improves air blast by adding oxygen to the reaction and insuring complete combustion of the ingredients. The aluminum extends the pressure pulse. The ratio of materials is formulated to obtain the lowest known processing temperature.

  • Systems and Methods for Generating Electricity Using a Thermoelectric Generator and Body of Water

    United States
    Filed

    A system for producing electrical power a thermoelectric generator including a thermopile, a hot junction, and a cold junction. A high temperature source may be thermally coupled to the hot junction wherein the high temperature source includes heat from within the earth’s surface. A low temperature source may be thermally coupled to the cold junction wherein the low temperature source comprises cold water from a body of water. The thermopile generates electricity from a temperature gradient between the hot junction and the cold junction.

  • Systems And Methods For Generating Electricity Using Heat From Within The Earth

    United States US20080223032
    Issued

    In one embodiment of the invention, a system may include a power generating means comprising a hot junction and a cold junction, a pump station, a high temperature source, and a low temperature source. The high temperature source may be thermally coupled by a first pipe system to the power generating means, wherein the high temperature source comprises heat from within the earth’s surface. The low temperature source may be thermally coupled by a second pipe system to the cold junction, wherein the low temperature source comprises water from a body of water. The pump station is operable to cause a heat transfer medium to descend through the first pipe system to the high temperature source within the earth’s surface and then to ascend through the first pipe system to the hot junction, generating electricity responsive in part to a temperature gradient between the hot junction and the cold junction.
