alternative energies - perpetual motion

[TETRASTORE]

is the first principle of physics.
since a cat if dropped will always land on the legs and that a stewed slice if dropped will always end on the part with jam, just tie a biscotted slice on the back of a cat and let it fall.
and here is the perpetual motion.

I reconnect to this post avoiding responding in a technical discussion (cuscinetti) not related to this topic.
remaining within the framework of the paradox and taking a view of the two laws contained in the enumerated wikipedia and given the definition of perpetual (what is destined to last forever or that it extends indefinitely over time), or even only that the inderogable condition is that the limit of time is not imposed by the obligation to supply energy, it is necessary to highlight that a third law has been neglected: the cat has only nine lives, so the bike cannot be considered perpetual but would cease to exhaust the lives, after which you should replace the cat .

apart from the parentheses, I want to enter the field of alternative energies that I have been interested in for twenty years and, looking on the net, I noticed that more and more frequently the solution of the perpetual motion of the wheel enlivened by plastic bottles full of liquid is proposed.
See you video 1, video2, video 3.
It is obvious that none of those videos are credible, even if a multitude of people fall, and in fact quest'altro video explains the commonly used make-up.
What I would like to report is the technical demonstration that this is impossible to achieve.
I attach an image with two positions of the wheel extracted from video 1 on which I indicated the centerpieces of the bottles full in half and the distances (in scale) of the points of application of the loads. Except for errors, it is evident that no pair is generated that produces a rotation to the right instead, the system would tend in both cases to turn left to find the balance condition. (the numbers in black represent the sum of the distances of the centerpieces of the masses to the right and to the left).
other verification can be done in the last video (where the make-up explains) detecting the following indicative data:
wheel number: 24 rpm
pulley/motor shaft ratio: 18
engine/alternator turns: 24x18= 432 rpm
the continuous current motor used as a generator, can produce a voltage of 12 vcc at the nominal speed of more than 10000 rpm for which in the case exposed it is not possible to obtain an alternating voltage that allows to feed an electrodomestic, although with a low absorption.
What do you think?

 

[Marco F inox]

in the many attempts to create perpetual motion, with moving organs, rotary species, there are many examples of rotation without make-up, i.e. without hidden external powers.
However, it cannot be said that the alleged demonstration, with a wheel turning without stopping, satisfies the definition of perpetual motion.
this because, for each organ in motion, there is a consumption of material, therefore the duration of an organ, which is always limited in time.
a rubbing, a bronzine, a bearing, will never give an unlimited guarantee of sealing and durability, precisely because it is impossible to eliminate friction, you can reduce, but never eliminate.
is therefore the friction that blocks a priori, any attempt to create the perpetual motion and will never be recognized, approved or patented.

the answer is simple.

within the

and how to say about the laws of thermodynamics, if I remember,

1st principle) you cannot win.
2nd principle) you cannot draw
3rd principle) you can not play
