Gravitic Motor Problems

Every Project face hardships. The Gravitic Motor is no different.

These notes compile the possible problems that this idea could have, that might evolve into critical flaws that render the idea impratical, and useless. As I like to say, the work to uncover critical flaws is akin to gold-sieving, you patiently work with the idea, trying to examine it through every angle, always questioning yourself

  • "Would this work?"

  • "Is this behavior backed by theory or experience of others on the matter?"

  • "What can I do to minimize this risk?"

The work on the Gravitic Motor Problems was at its infancy. We had only compiled a list of possible problems, but no real work was conducted in evaluating them:


  • The autonomy is too low;

  • Capilary action prevent us from achieving small displacements;

  • The table oscillates too much;

  • There is no repeteability in the table motion;

  • Water actually leaks from one side of the floater to the other.


  • Styrofoam cannot be drilled; the pin or hook gets loose;

  • The motor is too slow;

  • The motor's noise (dripping in water) is annoying;

  • Water dropplet splashes instead of forming a good water level.


  • With all components factored, a Gravitic Motor is actually more expensive than threaded rods;
