Alternative energy developer Ceramic Fuel Cells has hovered around 16¢ this week, its lowest level in about 10 months. While management remains positive about the fundamental need for alternative “clean" energy sources as global consumption continues to rise, investors have shown little interest. On Wednesday the company said it had begun generating low-emission electricity from its BlueGen unit in Victoria. About the size of a dishwasher, the BlueGen unit generates electricity in the home at more than double the efficiency of tradition coal-fired generators. While the share price was unchanged on Wednesday, the stock has shown sensitivity to market news. In March it jumped 3¢, or 16.7 per cent, on details of expansion into Switzerland and work with Japanese companies Mitsui and Osaka Gas.
