IS THIS A REACTIONLESS DRIVE OR A PERPETUAL MOTION MACHINE?

[George1]

Here are our last REAL experimental results.
1) Please look again at the link https://www.youtube.com/watch?v=xX14NK8GrDY&t=330s
2) From 3:45 to 3:48 we have Ma = 1 kg, Mb = 4 kg and V1 = 0.1 m/s. (Please consider only the "upper" zigzag device.)
3) From 3:59 to 4:01 we have Ma = 1 kg, Mb = 4 kg, V2 = 0.06 m/s and  V3 = 0.01 m/s. (Please consider only the "upper" zigzag device.)
4) (1 kg) x (0.1 m/s) = ((1kg) x (0.06 m/s)) + ((4kg) x (0.01 m/s)). The last equality unambiguously shows the validity of the law of conservation of linear momentum in this particular case.
5) (0.5) x (1 kg) x (0.1 m/s) x (0.1 m/s) > ((0.5) x (1 kg) x (0.06 m/s) x (0.06 m/s)) + ((0.5) x (4 kg) x (0.01 m/s) x (0.01 m/s)). The last inequality unambiguously shows the invalidity of the law of conservation of mechanical energy in this particular case. 
6) How to reduce friction inside the zigzag channels? The answer is simple -- by using permanent magnet slides. (There are literally hundreds of permanent magnet slide designs in YouTube and in Google.) Please look at the links below for example:

7) The permanent magnet slide design:
a) reduces friction (and the related generated heat) practically to zero;
b) reduces the experimental error (due to friction and to the related generated heat) practically to zero.
And if the above mentioned experimental error is practically equal to zero, then this experimental error can be neglected (as it is much smaller than 1 %).
9) Alternatively you can use electrostatic levitation, rolling friction instead of sliding friction, etc. Besides modern tribology (this is the science, which focuses on sliding/friction phenomena) suggests a great variety of high-tech materials and/or lubricants' which are also able to reduce sliding friction (and the related generated heat) practically to zero.
10) In one word, you can carry out easily the above mentioned experiments in your garage or in any standard school laboratory (or by using any other simple DIY (DoItYourself) methods).
Looking forward to your comments.

P. S. The above yellow head with the black spectacles must be read as number 8. (The system generates some permanent defect.)

You are simply an absolute amateur in the field of theoretical and applied mechanics for sure. You do not actually understand what are you talking about. Firstly educate seriously yourself in the field of theoretical and applied mechanics and just then take part in this discussion. Because otherwise you resemble a clown!

There you go abusing the members again.  Not good. Chill out.

Please excuse George he's a youngster.
                  but
Speaking of clowns..

Did you hear the one about the two cannibals ?

One walks up and asks the other "what's you cooking ?"

The other replies "clown"
Then passing a big spoon full,  asks " this taste funny to you ?"

Nicely said / thank you !

Better late than never.

Please understand, my clown joke was in no way intended
as insult to or in regard to you.

          with respect
