A solar thermoelectric power station
Abstract:The profits and costs for constructing a solar thermoelectric power station are evaluated. The key problems, such as the amount of thermoelectric materials and lead wires, the length of the connected wires and the energy consumption for cooling in the power station are analyzed. The construction costs can be reduced to a very low level while the parameters are optimized. The impact of the input power on the conversion efficiency is calculated. The result shows that the power output of about 8.3×107 kWh. km-2 per year can be expected in a solar thermoelectric power station in the northwest of China.
