A new wood composite thermal battery combines lemons and coconuts with modified wood. This innovative material has the power to store both heat and cold, making it a potential game-changer in the world of sustainable construction. 100 kg of it used in housing construction might save 2.5 kWh per day on heating or cooling, assuming an ambient temperature of 24°C. This material could be used for both exterior and interior building material, providing both transparency and energy-saving benefits.
