This one is intresting.

I don't know how it is faked but I do know that while using a
conventional alternator it cannot work.

Well he is not using an conventional alternator.  He rebuild the internal part with permanent magnets.  Did you watch it all?

Fake videos over the years, have come from all parts of the world.
There must be thousands of them on the web !
Some have been very elaborate.

Hundreds of them have been examined here at the O.U. forum.

In this modern age a video alone cannot be considered as proof... at all.

Only the details of the construction which then allows some understanding of
why it works and then its replication can validate a device.

So he says. 
Is there a blue print / schematic some where that I missed ?

Here is another video from the Tecnología Oculta site.

No question at all that this one is total BS.

The video in the OP is just a rip from another guy - Multi tech or something like that.  The Multi tech guy who built that had millions of views on it.  Everything he does is fake but makes himself a lot of money from youtube views.  Google (youtube) doesn't seem to give a damn about misinformation unless it is something negative about vaccines (which they are invested in).   Lots of ways to fake this - hidden wires, batteries etc.
