What's wrong with this

[Floor]

Work from gravity.

Since it's "all been tried before ?" and "humanity has not learned anything new in the last 1.000 years ?"
and since "there are no new available materials ?" and "resources like mineature super computers on our desk tops
don't exist ?" and "there is no such thing as the global networking of information and ideas and resources" and because
some say it can't be done, so don't even try! BS

Hi Floor,


I like the concept, tho the valve system may be tricky to implement. However, I think you must consider the waterpressure will rise, the deeper you go. Which is why you get a strong pressure feeling in your ears when you dive in a pool or lake down to like 10 meters.


But that does not render the entire concept impossible. It just alters the gain calculation. You may also think about a compressible floater that is compressed just as much as is needed to equalize the pressure diffrence, which would then result in a variation in buoyancy.


Merry christmas to you too.


Peace

One of the basic fallacies is caused by a failure to account for all the pertinent energy at any given state.  Calculate the gravitational potential energy at each state.  If you do the work correctly, you will find that going from a state where the float is at the bottom to where the float reaches the top results in a net loss of potential energy.

Ask yourself what causes the float to rise?  A. Denser fluid falling.  If you question that idea get some oil, water and food coloring.  Fill a vessel 1/3 with water.  Add a drop or two of food coloring to the water.  Then pour in vegetable oil.  The vegetable oil floats to the top.  The system finds its lowest energy state.  You will have to do work to force the lower density oil down, thus displacing a greater mass of water upward.  The same thing happens with a float.
