Title: No fall,no power...
Post by: iacob alex on April 30, 2011, 05:17:30 AM

......can be,in my opinion a first observation regarding the possibility to take out "free energy" from the gravity potential (statics).
     
       A longer fall means a greater velocity,so we can play more kinetic energy with our "toy"...

       A full up-down (180*) pendular fall ,is not alike a swinging balance...but you decide the way of acting :a power machine or a weight-measurement machine.

               All the best ! / Alex

Don't really understand your post. You want to show us something or are you another Archurian defeating Newtonians ?

   Hi !
There are a lot of topics,regarding the necessity to play a longer fall (for instance "Wheel vs. lever" and others...).
  All the best! / Alex

.....or give gravity time to act ("work") , so to develop self-motion in a continuous unbalanced arrangement .
We know that , a (single...) mass , if allowed to fall freely , " speeds " the vertical distance ( and kinetic energy...) proportional to the squared elapsed time , as follows :

We can take advantage from this increasing non-linear "stream" of "free" kinetic energy , and develop self-motion with the help of a simple continuous unbalanced configuration of two masses , playing variable/oscillatory leverage ( torque difference on the same side of the fulcrum ).

Hi alex:
   And at the end of the fall you have to move the falling weight to a position that will take less power to re-lift it to the top again. Ever consider the geneva engine?  Has a lot of potential.

    Hi Thaelin !
Regarding your comment : "...at the end of the fall you have to move the falling weight to a position...",take a look at : www.geocities.ws/iacob_alex/Some_Drafts/text013.jpg
By the way...how about the "geneva engine" (?!) ?

hi all i am working on a dc motor with a flywheel. when the motor is connected
to a dc source it turns and energy is stored in
the fly wheel this in the motor mode .when power is switched off the motor
becomes a generator then the charge is stored in a battery.. my theory for one
to get excess energy from gravity the flywheel has to have an acceleration more
than 950 m/s square or whatever the free fall gravity is..

i understand what you are saying distant and speed is equivalent..one has to exceed
free fall..
