Awesome Discovery or Simply disinformation?

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"

Thanks for the link, I'm starting reading it now.
But my question is..
Why the effect I have seen only happens when the red wire from the 24V@0.29A is disconnected?
If I connect the red wire to the fan together with the red wire of the 9.5V@0.55A the effect DOESN'T happens

When I connect 2 Red Wires + 2 Black Wires, the fan DOESN'T increases the speed. The fan only increases the speed when I connect 1 Red Wire + 2 Black Wires. I think if the second red wire is not connected, is impossible (IN THEORY) to get energy from the second wall transformer, so IN THEORY only the first wall transformer is drawing energy to the fan. So, Why the fan increases the speed when I disconnect the second red wire? If I connect the second red wire the effect doesn't happens.

Can you explain me why?

Correction, sorry:

@4Tesla
I'm reading little by little your link and I'm learning, thanks. But...
Look at the pictures:
All the experiment that you can see are made using a dipole connection for each one battery. In my experiment I have a dipole connection + monopole connection. Of course, your link has been very usefull for better understand batteries, but it doesn't answers my question (all experiment use a dipole connection).

@All
Strange batteries, are not a monopole connection. Strange batteries in the pictures means DAMAGED batteries.

The fan: 12 VDC @ 0.33A

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

The output voltages (from Supply Plugs)
is it  DC  (VDC)
or AC (VAC)

this must be very different in the application....

but in both way , very suspect
