    Undergrad Buoyancy/Gravity Concept - How to insert buoyant weight into water column?

    Ahh I see the flaw with this. Originally I had envisioned an insertion chamber underneath the water column where the object could be inserted and then the water could be 'dropped' on it. The same issue would rise though ... how to get the displaced water to the top of the column again without...

    Undergrad Buoyancy/Gravity Concept - How to insert buoyant weight into water column?

    That's been my stumbling block ... finding a way to push the object in with less work than it takes to get it to the top. If the object was not buoyant could it be dropped into B granted valve A is sealed? Say a rock or a metal object. I'm under the impression if Valve A is sealed it won't...

    Undergrad Buoyancy/Gravity Concept - How to insert buoyant weight into water column?

    I don't know about endless but it would be a start. I'm trying to sort out whether there is any way to insert a buoyant object at the bottom of a container of water. Gravity would of course have to supply the energy ... but if we can use buoyancy to raise our objects to that height in an...

    Undergrad Buoyancy/Gravity Concept - How to insert buoyant weight into water column?

    Hello all, I devised a concept a couple years ago for renewable energy and hit a stumbling block: How do you insert a buoyant object into the bottom of a water column with the smallest amount of energy? Recently I revisited the concept and found some similar work online including this...
