I'm not seeing the actual process how this works. The video is very vague and the article is very repetitive in saying salt and water is how it works but no schematics. We really do need to find a sustainable future to heating. Natural gas and other fuels are a huge burden on our planet.

When water is added to the salt, it releases heat.
Supposedly the process is reversable, so by adding heat the salt precipitates out.
"As long as water and salt are separate, energy is stored without loss."
The issue I see is that humidity may be a problem, so the salt needs to be stored in air tight containers.
