The irony is there's use cases for that waste heat.

- Utilities could use the extra boost of heat in winter

- producing potable water

The coin produced from these processes could then be used as tradable units. "Heat Coin" or "Fresh Water Coin" would ease the transaction of these resources.

Hence, we get to the root of the problem of any "Coin": it is inherently worthless without any real asset or unit of production to back it's value.
