Awesome Discovery or Simply disinformation?

[Magnethos]

I was just researching about the coanda effect (aerodinamic effect) with my new pc fan when I have just seen a strange effect. I don't know about electronics, so I want let me know your opinion.

2 Wall transformers. (A: 24 Volts @ 0.29 A,    B: 9 Volts @ 0.33 A)

TESTS I HAVE MADE
* I connect 2 black wires together and 2 red wired together to the fan. The fan seems to be running at the same speed like when is only connected to the A transformer (24V@0.29A).

* If I connect 2 black wires together and the A wire (24v 0.29a) it runs ok

But...
* When I connect 2 black wires together to the black wire of the fan and then I connect ONLY the red wire of the B (9V 0.33A) the fan starts running at a very high speed!!! Remeber that the red wire of the transformer A is not connected, only the black wire is connected.
You can see it in the picture.

This is only disinformation or is a Energy Amplification effect?

The fan: 12 VDC @ 0.33A

And the B transformer is 9.5 Volts 0.55 A, instead 9V @ 0.33A sorry

I believe this is as simple as you are just creating a common ground, which probably increases the voltage..  that is my guess.

It isn't a good idea to hook up two different voltages in parallel.  There isn't any free energy that you can get from this.

Also look up "common ground" and "floating ground"

Magnethos,

What kind of mains are you connecting to? 230VAC or 110VAC system?

Groundloop.

Magnethos,

Groundloop.

Here in Europe, the main is 230V 50-60Hz
