1.   Matrix isolation has given some surprising results in the study of vapours from molten salts.

2.   Significant technologies under development there includes improved stretched-membrane heliostats and pumps and valves to handle the molten salt.

3.   And that molten salt could add power to lithium-based battery designs that already have virtues of light weight and high storage capacity.

4.   Other high-temperature fuel cells are made up of an acid base or molten salt, which emit more pollution.

5.   The molten salt could then add power to lithium-based battery designs that are already lightweight and have high storage capacity.
