An evaporation sleeve is placed within a solar distillation loop apparatus to increase the amount of water evaporated by the apparatus. The central processing unit operates at a first clock frequency and the main system bus operates at a second clock frequency that is lower than the first clock frequency, responsive to the electronic device being in an active mode. Additionally, the system performs pitch corrected speed control in order to allow the detection and processing of a speech pattern without causing delay to an end user. The exposed portion of the silicon substrate is anisotropically etched through the wafer thickness down to conductive metal layer to provide an etched pattern consisting of a series of rectilinear channels and recesses in the silicon which serve as the silicon micro-mold.
