...or water ram,this so old and simple fluidic elevation system,against the gravity,can be,in my opinion a thought -provoking model for persons interested to imagine the "phantom of the mind" of this site.

      Thus and so,water ram or water,hydraulic ram can pump the water from a flowing source of water(input),to any point above the source(output),without  any power requirements except that of the water moving downhill(input).

      Here we have a simple logical abstract,not more that a wholly uncommon game,regarding the gravitational levels:input/down-"black box"-output/up.

      You know the established situation for an up-down pendular fall in gravity: (up-down)=+

       But for a ram pumping technique it seems that we have a new relation:     (down-up)=+

       The "black box" has "transparency" when we use water,fluidic matter...we know and apply it without a doubt.

        Now ,the next step can be a call into question:how about a "black box",that makes use of the same ram pumping principle,but this time with a solid state"flowing" system inside,due to gravity fall,only?!
