No, unfortunately it hasn't been created.

This has happened thousands of times throughout scientific history. It's always either delusionals or scam artists.

It has been mathematically proven that it is impossible for a system to increase its total energy without any inputs (as long as the laws of the universe do not change).

You can't get any energy from a magnet as this man claims (there's a thread in the Science forum where I explained to somebody why).

As always the man in the video only claims to have a 'prototype' i.e. it 'needs some energy input' just to 'demonstrate that it works' and that he'll 'be able to make it run entirely by itself soon, honest!'. He then seems to ask people to buy it in order to see for themselves, instead of subjecting it to scientific peer review (which would instantly make him a billionaire if he was telling the truth), so he seems to fall into the scam artist category.
