Polarized electric charge storage devices economically provide high available capacitance. The memory array has multiple memory elements for storing data. A resulting treated aqueous stream may meet thresholds desired for injection into a disposal well. The material has a refractive index that approximately equals unity for at least a predetermined wavelength of electromagnetic radiation to which the optical surface is exposed. Upper portion of the handle is curved to provide a predetermined shape to the head. Provided is a control server adapted to monitor an operational status of the communication link.
