The specific weight (also known as the unit weight) is the weight per unit volume of a material. The symbol of specific weight is γ (the Greek letter Gamma).
A commonly used value is the specific weight of water on Earth at 5°C which is 62.43 lbf/ft3 or 9.807 kN/m3.
The terms specific gravity, and less often specific weight, are also used for relative density. Specific Weight, Wikipedia

Therefore if the media of water or air are moved naturalesquely (and the trick is how to do this) then the bipolar gases are initially transformed into aetheric and ultimately into energetic stocks of subtle matter. These are then bound in the self-evolving juvenile media (air and water) and what has been increased in this way is rendered homogenous and specifically densified. That is to say, they intensify the carrying capacity and tractive force to such a degree that in such waters material with a higher specific weight than the transporting medium, even ore with a specific weight of 1.9, readily floats down the centre of the axis, where the strongest suctional force acts downstream and the strongest reactive force acts upstream in the form of a dynagen gradient, but which, however, has no effect on raw material structures to the extent that these do not involve life-forms.

At first this proposal was ridiculed, because according to expert opinion either the ore, having a specific weight of 1.9 and therefore heavier than water (= 1.0), would be left lying on the bottom or the pipe-walls would be heavily scoured within a short space of time, and therefore the proposal would not be commercially viable.
