Abstract: The disclosed invention is an improved TPW cell design that is designed to provide a method of removing contaminants from the TPW cell water, and improved resistance to breakage in shipping. An additional storage volume provides for transferring the liquid water from the cell body into the storage volume by inverting the cell, followed by a series of rotations. Subsequent distillation of the water into the cell body by a sub-boiling process (with vapor moving through a transfer tube and condensing in the cell body) results in removal of contaminants from the water in the cell body. The upper volume and transfer tube are configured so that transport damage is minimized by storing the liquid water in the storage volume during transport, and preventing any liquid water from moving from the storage volume into the lower cell body regardless of orientation of the cell during shipping.
