The Cartwright's sols are configured in Liz Butler's signature "Dimetrodon Array"
Despite the hardships which befell humanity following G-Day, specific technologies flourished. Chief among these was solar technology. This was in no small part due to Dr. William Isaac and his breakthrough discoveries. A genius in many fields, Dr. Isaac’s research greatly increased the scientific community’s understanding of solar-tech. Using Dr. Isaac's research and looking to nature's methods, scientists engineered biotechnological solar panels that were self-replicating and could essentially be “grown” like plants. Often referred to as “sols,” these organic solar cells were efficient and cheap. They had many uses, frequently utilized on vehicles, on water purification stalls, on residence rooftops and in solar fields like Hiawatha.
These strategically placed solarfarms could supply energy to three or four surrounding communities. The solar cells’ effectiveness was increased during this time due to the increased level of solar radiation reaching the Earth. In fact, solar radiation was so abundant that the solar cells became quite fragile. Constant monitoring and cooling were needed to prevent the panels from overheating and shorting the delicate circuitry. Technicians like Ali Rugosa, Gene Waterman and Colby Feliciano spent long, hot hours in the solar fields guaranteeing the performance of each solar cell.
