A New Thermophotovoltaic Cell Generates More Energy From heat Than A Steam Turbine

These TPV heat engines are the final piece of technology needed to enable extremely affordable grid-level thermal energy storage.
The crucial final step in proving that thermal batteries are a workable idea was the development of thermophotovoltaic cells. This is a huge step toward a society entirely free of carbon emissions and the widespread use of renewable energy. The technology has the ability to significantly reduce carbon dioxide emissions from the generation of power and is both safe and advantageous to the environment throughout the course of its full life cycle.
