A wireless networking system uses mobile and fixed transceivers to achieve a network with changing topology. The speaker incorporates a vented pole flux conductor and a vent adjacent to the diaphragm permitting the rearward acoustic output to propagate away from the diaphragm producing acoustic output as a dipole radiator. The fusion device is capable of being deployed and installed in both configurations. This heating and cooling mechanism produces or removes thermal energy as a product of the temperature of the combustion of air and fuel. The ratio between the area of the negative electrode 34a and the area of the positive electrode 32a is set to 1:2, thereby reducing element resistance to 74% that of the case where the negative electrode and the positive electrode assume the same area. The vaporization surface is then utilized as an electrode to form a plasma, and at least a portion of the deposit is removed with the plasma.
