Spiral motor...

Post by iacob alex »

.....at : www.thingiverse.com/thing:516978
A natural "free" spiral motion , can be a " counterpart " of the free gravity motion , or rotation vs. translation .
We can combine them (gravity fall and centrifugal/rotational "fall" )...something alike , you can see at :
www.triumf.ca/galleries/image/cyclotron-sketchjpg
A trebuchet manipulates the gravity fall of a great mass , so to sling ( take advantage of the spiral free trajectory / acceleration ) of a small mass , and...you know.
So , how about an "automatic" short arm-long arm ("non-throwing"...outside !) "modified" trebuchet ! ?

I built one of these many years ago. I still have the frame. It is cool to watch, for almost a full cycle. It has a "hard" reset point. Adding this as a counterpart seems like a bad idea. It is better to have a device that is always begging to turn at all times.

Hi !
The proposal for a modified trebuchet is intended for a full cycle (360*) :
-the great mass playing a circular (constant arm)/360* trajectory
-the small mass playing a half circle ( constant arm ) - half spiral (variable increasing spiral arm ) trajectory.
The purpose is to energize the "self" motion , if we keep going a continuous gravity unbalance on the same side of the fulcrum.
We can start with a "classic" non-working wheel at :
https://www.lhup.edu/~dsimanek/museum/m ... rp_ani.gif
...and minimize as a "modified" trebuchet (oscillatory one arm "wheel ) , at :

.....implies a continuous increasing/variable arm .
For a single "throwing sequence" ( no more than a half turn/gravity fall of the counter-weight ) , you can see the curvilinear/spiral trajectory , at :
https://commons.m.wikimedia.org/wiki/Fi ... Scheme.png
A possible self-powered gravity motor , as a "modified " trebuchet , can take into consideration , as a starting point , at :
www.feynmanlectures.info/solutions/part ... _sol_1.pdf
So , we can play a continuous variable arm due to the interplay of gravity ( fall...) and rotational inertia ( "fly"...)...or "fall and fly".

.....as a possible man-made device , has a multitude of similiarities with several natural phenomena :
https://en.m.wikipedia.org/wiki/Logarithmic_spiral
Now...how about a free fall of a rolling ball due to gravity ,as an input for a vertical "free" spiral track motion vs. a Galileo's pendulum ( mgh " interdiction " regarding a closed loop between two gravitational levels...) ?!

.....as a fluidic " style " ( continuous matter ) , at : http://energythic.com/view.php?node=197
Now , in a possible gravity powered device , we can play :
- gravitational acceleration
- centrifugal acceleration
- Coriolis. acceleration
...in such a " solid state " non- continuous matter arrangement( on a spiral track ) to " open " the rotational inertia " sprinkler" ?! ( " excess " energy )...as a " modified trebuchet " ?!

AL_ex,

http://energythic.com/view.php?node=197

A tremendous Thank you for the above link!

When it gets in to the Coriolis effect and pressure it is compatible with my thinking and design of my own liquid powered attempt.

Anyone interested in a molecular mass attempt for PM needs to read this link!

@ ME, I hope you pick up on this!

Also worthy of a read if you find yourself bored with TV or cannot sleep!

@ ME, I hope you pick up on this!
It seems a relative easy thing to try out in-real-life when one already has the right equipment and space, especially when it is expected to produce excess energy.
I'm a bit doubtful on all three.
The first two could be considered an excuse (needing: a rotary joint, tubing and the will to rain on the neighbors) but as far as I managed to read I simply doubt the paper's doubts to attempt such risk. Besides that, I have no doubt other people already tried it out.
It's not helping this guy gets concerned about the validity of his own use of computational fluids. The shown calculus should either be undoubtedly correct, or otherwise be supported by an experiment or used to gather some indicators on how such experiment would perform. But (at garden hose level) we don't initially care about those numbers as long as Energy(out)>Energy(In) we should all be happy, no matter the percentage.
As it concludes with speculation it invites the same kick as initially directed towards Victor Schauberger.

I think the investigation should go something like:
* For a given input energy (converted to water pressure) how much does the angular speed increase with an increase in tube-length laid down in (Archimedean-) spirals on a rotating disc so it exits (tangent) at a given radius.

Coriolis is the other fictitious thing next to centrifugal.
It's an effect observed in the rotational frame - both illusions of linear momentum in the inertial frame. Abusing them to become beneficial in the inertial frame will at least be a cause for friction or actually robs rotation...(I'm open for good suggestions).
From this I hypothesize that there's no expected significant change in rotation, and likely gets lower when friction increases with tube length. (All the better when this is somehow wrong).
At least as a base-line the shortest tube length (the sprinkler situation) it's agreed upon that there's no energy gain.
I indeed have to look further into it why a longer tube laid in spiral shape should have a sudden gain.

Viviani's window! A very interesting curve and definitely worth a look!
It combines 3 basic elements: a lemniscate (a figure eight), a parabola and a circle.

A parabola and a circle worked out pretty well for NASA. :)

Hi !
Regarding Provatidis&Tsiriggakis proposal , at :
http://energythic.com/view.php?node=212
...their proposal is "ill-matched" / unbalanced
Something alike , at :
https://youtu.be/SgvSNgWk430
...but the "offer" to handle a single mass double rotation is unbalanced,also.
For a "clean" centrifugal tractive vector ( pulling one-way ...rotational inertial effect ) , we can start with an "old" syncro-rotating eccenter/vibrator , at :
http://www.hajtech.hu/vibrator/sceltavibratoree.htm
...but my suggestion is to "quadruple" this syncro-double rotating of masses.
To play gravity motor ( energy ) and inertial propulsion ( transportation ) , we need to apply the First Law of Mechanics ( the rotational effects of this "misty"/"mystic" inertia )!?
