Gravity "wheel" concept...

[onthecuttingedge2005]

Mercury liquid metal is 13 times denser than water. It's a lot of fun to
think about how to substitute mercury for water in a buoyancy machines.
The forces though would really build up, though, to potentially
dangerous levels. Since mercury vaporises at room temperature
it really is a forgiveless experimental medium.

Hi Mark.

you can use the same technique for water in the diagram I showed but water won't be as efficient as mercury because of the boiling point differences.

if you could lower the boiling point of water then the efficiency will increase.

the lower boiling point helps the medium to break the Capillary bond through thermal pressure. pretty simple thermodynamics.

    .....has an applicable interpretation at   http://peswiki.com/index.php/Directory:Gravity_Motors   ..."for a rotary device to *work*,is to achieve a full 360 rotation,with acceleration between each complete turn".

         This viewpoint counts upon a "full 360 rotation,with acceleration".

         Simply,a full up-down fall in gravity,of a pendulum ( fulcrum-rod-bob) ,achieves a 180 rotation,with accelearation  ...we have it so easy.

         The next,and only step,is to keep going this motion to a full 360 rotation,with acceleration...nothing more.

         So,let's think in a "pendular manner"...

  .....in a short,obvious expression :the "wheel" is in fact a variable lever.

      The plain,clear public demonstration you can find on  youtube.com   with "Cirque du Soleil" (the show with one man rotating a huge lever...).Enjoy it...

      If you replace the performer with a simple movable joint mass,and the lever is big...we can hope about the "self".

.....resumes in a simplified symbol , as a pendulum with just barely enough energy for a full swing :

To have "enough energy" , we need an in-out storage ( the best one is inertia...) and a variable counterweighted pendulum ("minimal wheel") , so to play oscillatory leverage...or "wavering gravity ".

.....this time as a continuous unbalanced ( swinging or rotating ) " modified " weighting scale ( variable/oscillatory leverage ) with a starting point...somewhere at :
