Not doing this. I might do it partially in a couple years depending on the state of the economy. But I still have hope. Perpetual motion equals God making something out of nothing.
It's interesting to note that the whole body absorbs water and not just your stomach.

Medical student's opinion:
The pressure acting on your cells has 2 forms:
- Oncotic pressure due to the difference in tonicity of the solution vs the cell
- Hydrostatic pressure due to the difference in physical pressures of outside vs cell
Swimming in hypotonic solution (your cells are hypertonic to it) will cause your cells to absorb some water. This is why your skin wrinkles (absorbing water and expanding your skin beyond the normal size).
However, absorbing that water increases the amount of water in your body/cells which have a limited ability to stretch. The more water absorbed the less they can stretch and therefor the greater the amount of hydrostatic pressure pushing back. (Think of blowing up a soccer ball, at some point it becomes very difficult to put more air in)
Eventually the hydrostatic pressure pushing back will equal the oncotic pressure pushing in and your body comes to equilibrium without popping.

The fluid goes into your stomach, and is then absorbed into the body. Most of your body is composed of water. It goes into the cells, and hydrates the rest of your body and organs. The excess is excreted through the urine and the bowel. Water is essential to the body. You will die from a lack of fluid more quickly than from a lack of food.

You need water to hydrate, but too much pure water can upset your electrolyte balance.
hypertonicity (noun).
Compare: hypotonic, isotonic.
See also: tonicity, osmotic pressure, solution, solute, concentration gradient
Having a greater degree of tone or tension.
Having a higher osmotic pressure in a fluid relative to another fluid.
Of or pertaining to a solution (e.g. extracelllular fluid) with higher solute concentration compared with another. (see: hypotonic, isotonic). For example, if the extracellular fluid has greater amounts of solutes than the cytoplasm, the extracellular fluid is said to be hypertonic.
Supplement
A cell placed in a highly concentrated solution will result in the water molecules diffusing out of the cell. Eventually, the cell will shrink. It should be noted, however, that not all cells in a hypertonic solution will shrink. The cells have ways to circumvent hypertonicity (see osmoregulation).
