Again:
Whirlpools do not create energy. They use it. They use it to convert the waters motion to a vortex. This can potentially be harnessed for power. A bit of gravity leading the water downwards will add to the power output.
But the whirlpool is still getting its power from elsewhere! Specifically, gravity.
This added energy is the same reason that dams have a reservoir with a higher water level than the outflow. The water can flow down the intake pipes, gaining momentum
from gravity (that'd be a form of potential energy, for you non-physics-inclined-types) as it does so.
Additionally, you're questions about the shadows beneath disturbed water have been answered. Although appearantly you didn't see fit to read the responses on the first page.
For your convenience, I will quote three posts which answer the "shadows" query below.
It's called
caustics.
If you look closely, you'll notice that for whatever dark portion there is, there is an equivalent lighter portion. The total amount of light is constant (excepting small differences in light absorption and reflection).
- Dr. Trintignant
Why, other than analogy, should we consider a shadow to resemble a black hole? Just saying it is not enough.
Have you considered reflection and refraction to explain why the light of your flashlight is not transmitted evenly through turbid water?
Refraction, refraction, and, as mentioned, caustics.
The shadows under your whirlpool are there for the same reason you see differences in light distribution under water in pools, ponds, lakes and oceans.

Remember, this is your claim.
The burden of proof is on you to show that physics is wrong (i.e. that whirlpools do not use outside energy, but instead generate energy), and that the patterns of light and dark you see are not caused by caustics, reflection and refraction.
These phenomena are well explained by accepted science.
You want us to consider alternatives,
provide the evidence!
Your questions have been answered. Now please stop asking questions and start answering the ones put to you.
Or if you don't, at least provide me with a good reason for not ignoring you from hereon out.
