A team of researchers has developed a stable battery cell that can directly convert heat into electricity, providing a way to use geothermal energy in a sustainable way.According to a recent study, while currently used renewable energy sources such as wind and solar energy have their merits, there is a gigantic, permanent, and untapped energy source under our noses: geothermal energy.Generating electricity from geothermal energy requires devices that can somehow make use of the heat within the Earth's crust.Findings were published in the Journal of Materials Chemistry A.Researchers have made great progress in the understanding and development of sensitized thermal cells (STCs), a kind of battery that can generate electric power at 100 degC or less.Several methods for converting heat into electric power exist, however, their large-scale application is not feasible. For example, hot-and-cold redox batteries and devices based on the Seebeck effect are not possible to simply bury them ...
