Heat energy can be added to or removed from a GHEX Thermal Battery at any point in time. 13. The one common principal of these Other Thermal Batteries is that the reaction involved is generally not reversible. 14. The mass of the oven acts as a'thermal battery ', which slowly releases heat over time. 15. Since a phase change is not needed many more materials are available for use in an Encapsulated Thermal Battery . 16. Early examples of thermal batteries would include stone and mud cook stoves, rocks placed in fires, and kilns. 17. Other related chemical thermal batteries exist for producing cold ( see Instant cold pack ) generally used for sport injuries. 18. The capacity of the solar collector array is dramatically different when it is applied to a phase change thermal battery system. 19. The "'Grom "'( meaning " thunder " in gripstock and thermal battery coolant assembly electric unit. 20. NanoFoil can be used as a pyrotechnic heat source, a replacement of potassium chlorate / iron pellets, for thermal batteries .
