Thinking on a beach...

...or gravity ,this mass energizer,performs to be an invisible(potential) flow.Prof Feinmann imagined the potential field,as a "dry" water equivalent.This flow seems as if "frozen",when there is no mass(nothing "to carry"),or the mass has a support(ground,"frame").The same "dry" water,becomes "wet" flow,fluxive,"ready to carry" a mass with no support ,in an accelerating manner,energizing the free falling body.Where is a flow and a basis,ground,shore,there we have a relative motion,a power of movement, that can we can transform,transfer,use,handle in some way.So we have a flow(gravity),a fulcrum(support) and a missing in-between "figure",able to collect this ever fresh and free gravitational power.The power of the gravity,in the same line with the nature of the imagination is to flow and not to freeze.

...that is the weight of a mass  "m",in the gravitational field  "g",versus(against,considered as the alternative of) the momentum(the product of the same mass "m" and velocity "v" developed in a "t" time free fall/fallgeschwindigkeit  v=g*t/),can be a supposition,a first step,so to conceive a gravity machine.We must distinguish a static operation about mass( a weighting machine swinging a little to and fro at an horizontal reference line) from a dynamic performance with the same mass(intended in a gravity "flow" machine in a full up-down rotational fall).The fall in gravity is energizing the mass:the static weight "m*g" becomes a (or like...) a dynamic weight "m*g*t".If an object is moving in any reference frame,that is has momentum in that frame.A free fall calls for m*g*t and a pendular descend is something more than an usual drop in gravitation...remind the greater "g" of the "falling chimney",or "falling stick" lab demo.In the past,in early science gravity was seen as a "magical operation"...and really that is.All the Bests!/Alex

...so to Aristotle, which stated that moving objects,only continue to move so long as there is a power inducing them to do so,can be a way to clean our thinking in this  huge amount of the opinions  regarding natural mechanical  movements.
We are interested about "a power inducing motion..."
The  Aristotelian division of the general motion into mundane and celestial ,is  correct and can be a good starting point to think about it.
  About  mundane  motion we know  the  rule: inertia,lifeless  that is constant velocity,no  acceleration.
But  how about the  gravity fall ,and the spinning planets?
The common inertial  stage,thinking  about  gravity  fall,  moves  from "lifeless" into "full of life",from  constant velocity into constant acceleration.
Have we an inertial  "discontinuity",here on the  up-down beach  of the planet?
The story can be long...the words are  "arrested" by  many standard definitions,but for us,in a simple expression,dreaming to collect power,as on a river(a material flow),this time  we must consider that  the flow is unseen,potential(needs a mass-marker) and inside(thru) the mass,adressing to the atomic nuclei,it  seems.
We can call this T(translational) inertialess(opposite  to inertia,as life is to lifeless).
Reminding about the moving planets ,we can call their motion as a R(rotational) inertialess.
Again,reflecting to Aristotle,we have names for two kind of natural celestial movements  and a distinction between two kind  of inertia(what a name!?).
A pendular fall in gravity,with a fixed fulcrum,changes a vertical motion into a rotational motion,a regular and symmetric trajectory.
A pendular fall,with a mobile fulcrum(Milkovic's  style) changes a vertical motion into an asymmetric trajectory.
Thinking that the basics is equilibrium,the same inertia,but this time we can have two different situations regarding the interplay action-reaction.
By the way,pendulum is a wonder toy:gravity is the arm,Earth is the fulcrum/pivot and Moon is the bob.Two similar systems,as seen at a first line.
Can we play a "celestial game"?For the time being we have the key words:inertia,inertialess,symmetry,asymmetry,gravity,lever and pendulum.Can we play asymmetry inside the symmetry?!

....we are living in,the gravity,seems to be   in an apparent conflict,with the First Law of the Mechanics ,that is Inertia.

    Usually,a body moves with a constant velocity/impetus and direction(linear,rotational movements) if not disturbed by an outside action.
    But how about a vertical free fall?...can be this one a kind of inertial "discontinuity"?
    This lack of coherence of inertia,can be a basis to think that energy from the "empty" space changes the location,is hauled in some
    local volume pointed by massive mass?
    It can described as an invisible 3D flow,flux that is manifested sometimes as a "fixation'' of the objects,but occasionally as a real flow
    for the free falling masses.
    On the beach,we know to gather the power of a river flow or of a wave balance...
    In the same line,idea can we imagine something nearly alike that "loads up",let's say a gravity powered device?

.....that we can notice at an old pendulum clock(and not only!),so a pendular motion in general mechanics,sometimes seems to be  the equivalent of a wave that plays up and down,on the spot.

     To collect energy of this type of wave,we need a median floating support(as a fulcrum).

     For an advancing wave to the beach,we have as a support,fulcrum  the shore of the sea.

     For these two situations,we can imagine easy pendular arrangements to get power from the sea.

     Now,if look "up" and we consider our position as "on the beach" of a huge ocean,can we contemplate the permanent presence of the gravity .as an incoming invisible wave from the outer space?A falling mass is as an wave of energy coming to us?

     If we can use a pendulum,as a concise symbol of the phenomenon(and power collecting set} for the sea waves,the same remark  coresponds for gravity.

     The swinging pendulum of a mechanical clock is as an up and down sea-wave on the spot.

     An incoming wave to the beach,calls up the idea of a tumbling pendular motion.

     Really,the common,well-known pendulum(pivot-arm-bob) can not be considered as a gravity power collector.

     What in fact would be required,is that the pendulum bob shall go up at the further side of its swing,higher than it went down on this side...which is not possible,anytime.

     The problem has one more step:   can we develop the pendular motion symbol,in such a way to get a tumblig pendulum equivalence,or a self rotating pendular motion?

     If so,we have a natural power at any time...
