"Earth's water brewed at home, not in space" Sep 2007

If the planets were still submerged in a thick hydrogen-rich solar nebula after they formed, as our Japanese brothers suggest, then it's not much of a stretch to imagine that every void in the Earth's porous sub surface would be filled with ... hydrogen. Volcanic action would open and close those voids trapping hydrogen underground and subject to density, pressure, and heat. With all that solid oxygen nearby ... you get water.

This would solve the biggest problem with my theory ... putting enough hydrogen underground with the solid oxygen.
