Hi Sevich!I am not a handycraft man,I am sorry.My tools are paper and pen,only.More,I am a visiting person for the time being,so the tests are for the future,I hope.About Tesla,I know that he is from Croatia,but it seems that his real native family is not from Croatia(a not checked information ...),but from a neighbour country...I know that you,the former yugo-family,croatians have a historic "game" with serbians(what a pitty!),so I try not to make confusions,and not to touch your sensibility.All the Bests!/Alex

Hi Sevich! I am from Romania,a neighbour of the former proudly Yugoslavia.Without Tito(a croatian!) ,Serbia remained alone.I know the story.History is bunk:few people make it and the majority lives,feels pain about it.No more comment. Thank you for the enheartening;as you see my "flag" is pendulum for a gravity engine.Some people are imagining a wheel(many spokes).In a way,my concept,a counterweighted pendulum(an unequal lever with two masses at every end of this one) is a "minimal wheel',with two spokes ,only.The problem is that a wheel with two spokes/a lever in fact/ allows a longer time to fall for the driving mass,so to accumulate a greater velocity V=g*t,in this way a greater acceleration and momentum:a mechanical unloud,similar to an electric discharge .That's my opinion.It is the difference of opinion that makes the things to advance,to step forward.Best Regards!/Alex

Hi Sevich!Your "banana shape" pendulum is so interesting,from my point of view...because it can be similar to my vision(your comparison,is artful this time...).If you take a look at my web site      www.geocities.com/iacob_alex/Stellarotor.htm    and there you click on New!New Drafts! you can  understand me better.A Happy New Year 2007!/Alex

Hi Sevich! A Happy New Year! from the North,the opposite my residence.How about fire,in your so hot summer?Now about your message.What's in a name?Let's open the books.Warp can be:bend out of shape/twist/turn/wretch/contort/deform/swerve/curve/deviate/bow/angle/variation ...and more nuances,maybe.The problem of a godfather,you know,is inspiration.Your "load & discharge" remark about rotopendulum is helpful to understand the two strokes timing.But you see,all is related to inertia(rotational inertia),not to gravity.We turn this pendular shape,so to get push(we need two connected,synchronous,opposite spinning ),a tractive vector.If you search at this forum the topic "Antigravity/Other antigravity machines and Devices/Rotopendulum"  ...you can understand me better.By the way the tag antigravity is an "unhappy" one.Again,what's in a name?Nothing more,that you can imagine,comprehend and handle,mainly.We know play gravity and rotational inertia:that's enough.This anti-....seems to me superfluous,uncalled for the real world.For fiction movies,science-fiction ,playtime it can be fun.For the people that are in a hurry to embrace reality,this term is as you kill the time of our so short living passage...at my age/about 63.So,again A Happy New Year! Sevich.All the Bests!/Alex

Hi Gaby!I made a short visit to your web site:it's interesting,and I will return again,so to get some possible suggestions.Thanks, for your nice words.For a time,I am not living on my basic residence,so I can operate with messages on net,only.In a way,I am not an handycraft man,I prefere "paper and pen",so to pass over,explore the huge soft forrest/aquarium like a monkey/fish ,in short and rapid lonely jumps/tours.About my web site,I believe that an elementary drawing is worth more than a lot of words.We are living now,sometimes,a time of simulations,a kind of Jurassik Park Science,on accasion, as you can see on net.For this ,I prefere the old Middle Age style designs:it's open,with any ruse,trick.By the way,my web site is old.What you can see at "Related images",now are stored in a cellar...waiting to be disposed at the garbage.Long time ago,I put aside on the fire,a half thousand designs about PM...as to escape from a burden...then,my conclusion was that in a "quiet lake"/gravity we can't imagine any self moving wheel,device.After years and years,thinking about IP/inertial propulsion(again about a thousand of designs...),with a new image regarding gravity(sometimes as a quiet lake,sometimes as a huge energizing flow ) and about the fact that ,the mechanical world of dynamics is playing on a double stage(basic inertia and gravity as an inertial "discontinuity"),again I tried to imagine the things in a different manner.This one,was discovered in one remaining designs of the past time.As in life,in a long travel,you are determined to carry what you need ,only.Sometimes we throw some things,that we really need,but the mind is a different storage:virtual.So,the memory can help us.All the Bests!/Alex

...can make us think about a facile setting side by side.

   Any design that takes into account a wheel (many spokes) or a lever(two spokes only) concept is equivalent,with a fall in gravity that follows a circular,or curvilinear track...a particular inclined plane.

   The most noticeable characteristic of gravity fall (this  "invisible flow"...) is his nonlinear development with the  time  factor:  "g" is a constant acceleration,so we can get on this inclined plane, an ever increasing velocity (kinetic energy)...if...we let it fall rather more time

  In this situation,the lever concept seems to have a certain advantage....

   ...concept , setting side by side,becomes essential ,when we take into consideration the measurable quantity of movement,that we can get out ,due to gravity fall.

            The hub and the spokes,usually are figured as a common,rigid body that can rotate  in a single manner: with a collective angular velocity.

            The hub,adds the effort of all spokes.

            The contribution of any spoke is variable,not only owing to the momentum's arm ,but especially due to their free fall velocity.

            Here is the point: in any sequence of the process,the spokes ask for some individual angular velocities.
 
            In this way,instead of  "an army of one" effort,we have  "a nonsense stampede" stess : at any time,some moments are pushing,some moments are pulling....and their possible summ working effort, becomes smaller.

            Here we have a "to be ,or not to be " problem : before to discard any  "wheel  concept" design(more than two spokes),give them the last chance,that  of two spokes only.

         Hi Cameron !

Your question up-there can get a multitude of answers...

My answer is this:if in the future we will be in a different planet(like Mars...),with no other flow(do you said rivers?),but gravity, we need to know how to take out power from this only source...
