Abstract
The embodied invention is a compact TPW cell design with an upper storage volume that is used to remove contaminants from the TPW cell water. To remove contaminates, the TPW cell is inverted and rotated so that the cell body water completely drains into the upper storage volume through a transfer tube. Then the TPW cell is then rotated to vertical and cooled which transfers the cell body water back into the TPW cell by a sub-boiling process. The water impurities remain in the upper storage volume and the cell body water has been purified of contaminates.

A triple point of water cell with an attached storage volume facilitating water purification comprising:
- A) an inner tube that is closed at one end and open at the other end,
- B) an outer tube that is closed at one end and attached to a transfer tube at the other end,
- C) a storage volume having a central opening,
- D) said inner tube is positioned inside said outer tube thereby creating a water cell volume between said inner tube and said outer tube,
- E) said central opening, said inner tube, and said outer tube are substantially coaxially aligned,
- F) said transfer tube that is connected between said water cell volume and said storage volume,
- G) said transfer tube extends into said storage volume and serves to transfer water into said storage volume, and
- H) an end of said transfer tube extends above a water liquid free surface level of said storage volume when said storage volume contains substantially all of cell body water contained in said triple point of water cell.
A method of purifying cell body water in a triple point of water cell comprising:
- A) providing a triple point of water cell comprising:
- a) an inner tube that is closed at one end and open at the other end,
- b) an outer tube that is closed at one end and attached to a transfer tube at the other end,
- c) a storage volume having a central opening,
- d) said inner tube is positioned inside said outer tube thereby creating a water cell volume between said inner tube and said outer tube,
- e) said central opening, said inner tube, and said outer tube are substantially coaxially aligned,
- f) said transfer tube is connected between said water cell volume and said storage volume,
- g) said transfer tube extends into said storage volume and serves to transfer water into said storage volume, and
- h) an end of said transfer tube extends above a water liquid free surface level of said storage volume,
- B) warming said cell body water until it becomes liquid,
- C) rotating and holding said triple point of water cell until substantially all of said cell body water drains into said storage volume,
- D) rotating and holding said triple point of water cell until said substantially all of cell body water drains from said transfer tube into said storage volume,
- E) rotating said triple point of water cell so that said storage volume is above said water cell volume, and
- F) cooling said water cell volume causing a reduction of vapor pressure in said cell water volume thereby enabling said cell body water to return to said water cell volume by movement of water vapor between the two volumes.
