Laurence,
How it works:
Charging:
Energy from renewable sources heats the sand through resistive heating or solar concentration.
Storage:
The heated sand, which is typically a mixture of quartz and silica, retains the heat for extended periods, even months.
Discharging:
The stored heat can be released to heat water, produce steam, or power other applications.
Why sand?
Affordability and Availability:
Sand, especially quartz sand, is readily available and relatively inexpensive.
High Specific Heat Capacity:
Quartz sand has a high ability to store heat at a high temperature.
Durability:
Sand can withstand repeated heating and cooling cycles without significant degradation.
Long-Term Storage:
Sand can store heat for extended periods, making it suitable for seasonal storage.

#18 If you distrust each other enough to consent to wearing these...maybe you shouldn't be together in the first place?

Rebecca,
Why would you consent wearing one if you're cheating?

#18 How? Does it notify when they take it off? I can't imagine how it works better than outright asking.
