I am sharing this pond design with you all, that I have made, named for the beautiful geometry imparted to it by the septfoil  current channel accented by 12 Tesla valves.

The purpose of the design is to harness thermal energy to produce or maintain a current. The design splits the pond into two ponds, one deep, small, and cool the other large shallow and warm. They are connected by a circular channel which employs Tesla valves to encourage a unidirectional flow. The direction of the current flow is counter-clockwise in order to synchronize with the gravitational  Coriolis effect (northern hemisphere). The heat differential between these ponds is what powers the flow of the current. I am not sure if this concept will work, but did some calculations that are reassuring. It takes around 30kWh to heat 10,000 liters. There is a lot of energy warm water that could be harnessed.

Why would you want a pond like this, assuming it works as presented?
1. Better nutrient cycling  and oxygen content
2. More intensive aquaculture. With these two connected ponds, you could raise different types of fish that required warmer or cooler water or that eat different food types.
3. Natural swimming pool. With the big pond to keep it healthy I think the small cool pond would make an ideal swimmin hole.
4. A S T H E T I C maybe I am too full of myself, but I just think it looks awesome!

Some practical considerations for construction: The channel must be deep 2 meters was suggested in order for a healthy current to form. The big pond will be the same depth as the channel at it's deepest point (the intersection). The deep pond has to be very deep like 10 meters in order to benefit from geothermal cooling, I think this is important to maintain a temperature differential that the current will be constantly undermining.

Big thanks to users Myron-Platt for the tesla valves, and to s.-ayalp who gave wonderful insights into the construction of such a pond.

Thanks for listening! Hope one of us builds something like this one day soon. I will be constructing a model soon as proof of concept, will update when I have some results!

    How are you planning to keep this pond full? Has this project been moving forward?
