194 degrees, could be higher...
They say the waste is contained such that the external temp of the storage unit does not exceed 194 degrees F, for geological reasons.
I assume it could be contained differently such that the temp reaches/exceeds to boiling point of water...
A lot of folks in this thread are thinking along the same lines. Why not store this in a heat exchanger and continue to use the energy for productive purposes? At minimum it could heat and power the facility where it is processed.
Must be a good reason they don't do this. But I'm stumped as to what that would be.
