MUMBAI, India, April 10 -- Intellectual Property India has published a patent application (202441074525 A) filed by National Institute Of Engineering, Mysore, Karnataka, on Oct. 2, 2025, for 'device for thermal energy retention in soils.'
Inventor(s) include H S Prasanna; Nikhil Joshua L; Suraj T S; Tejasvi Swamy; U Abhay Shenoy; and Unnam Anil.
The application for the patent was published on April 10, under issue no. 15/2026.
According to the abstract released by the Intellectual Property India: "The invention provides a device for assessing and utilizing the thermal energy retention capacity of soils. The device comprises an outer cubical enclosure (1) and an inner cubical enclosure (11) arranged concentrically to define an annular insulating space (2) filled with glass wool. A removable lid (3) is provided with a central opening to accommodate liquid lead (4), heated by a tungsten coil (5), thereby transferring heat to a compacted soil specimen (8) placed in the inner enclosure (11). Thermal sensors (6) inserted through ports in the lid (3) are connected to a data logger (7) for recording temperature variations over time. The device enables controlled heating of soil specimens for up to twelve hours, allowing accurate determination of thermal diffusivity and retention. The invention offers an eco-friendly, cost-effective, and reproducible method of evaluating soil as a medium for thermal energy storage with potential renewable energy applications."
