A solar-powered lighting apparatus having a light transmissible shade coupled to a housing that receives a solar cell, a battery and at least a portion of a lighting element assembly. A single evaporator is located adjacent both drawer cavities and is partitioned to keep the temperature in both drawer bins approximately equal. An individual traffic signal is represented in the database with data indicating the traffic signal’s geographic location and other attributes of the traffic signal such as an arrangement of lenses in the signal, an indication as to whether the signal is vertically or horizontally oriented, a height of the traffic signal over the roadway, and others. The host computer utilizes the virtual to physical address translation data to access data pointed by virtual memory addresses that were used by the target computer, and then debugs a fault by accessing the data by reading the physical memory addresson the host computer. A fuel cell including a polymerized metal-coated carbon article as a working electrode.
