Picture a half a pyramid (tried to ChatGPT it but not even close)
The walls are dual glazing and the gap between them are a vacuum creating a dewars flask so the ambient temperature doesn't occlude the evaporation from the sun, even if it's cold outside.
The evaporated water runs up the sides
of the half pyramid and condenses small pool at the tip with a small hole in one side that the water runs out of creating a perpetual fountain from the condensate.
The picture is about 10% accurate but I lost interest trying to get it illustrated. AI programs will eventually learn to follow simple directions like "draw a half pyramid made of glass" but we're not there yet. At least I'm not.
So you'd have two decorative flows of water, drops condensing on the sides of the glass looking like rain on a window and the little fountain.
Again, the drawing couldn't be more inaccurate but it got the glass part right. Sort of.
Sort of except for not even close.

Not entirely sure I have it right how this is supposed to work? .. but I see no reason to let that stop me ;) |
|

Isn't the definition of a fountain pretty much that the water is expelled at force from the ground or floor, wouldn't this be more like a dripping tap (at worst, or a waterfall at best), ergo, pretty much the reverse of a fountain? |
|
| |
A water feature certainly, but is it a fountain? |
|
| |
I hear what you're saying and yes. I don't think the flow would be particularly impressive, that's why you'd have it "framed" by this huge glass pyramid and dropping 3 or 4 stories. Even if it was a small amount, it would splash and cause ripples and you've be able to say "That's from evaporation only." which would be mildly interesting. |

Wonder if ChatGPT can give me a flow rate. Stand by... |
|
| |
Can you give me a flow rate from my solar powered evaporation fountain? Give me an evaporation rate for a 100 foot square pond on a sunny day where the water is enclosed in dual glazing with an evaporated vacuum between the layers of glass forming a dewars flask. |

To estimate the evaporation rate from your solar-powered evaporation fountain, we need to consider several factors, including the solar radiation, water temperature, surface area of the pond, and the unique design of the dual glazing with a vacuum (acting like a Dewar's flask). |
|
| |
Key Assumptions:
Solar Radiation: On a sunny day, the solar radiation can range from 200 to 300 watts per square meter (W/m²).
Surface Area: The pond's surface area is 100 square feet (approximately 9.29 square meters).
Water Temperature: Assuming the water is heated by the solar radiation to a temperature where evaporation is significant (around 30-35°C or higher).
Efficiency: Since the pond is enclosed in a dual glazing with a vacuum, there is minimal heat loss, maximizing the energy available for evaporation.
Simplified Calculation:
Total Energy Absorbed by the Water (Q): |

(bla bla bla etc etc. Lots of chalk board fancy rocket sciency looking math) |
|
| |
Conclusion:
With the given assumptions, your solar-powered evaporation fountain could evaporate about 3.7 liters of water per hour on a sunny day with the described setup. This rate could vary depending on the actual efficiency of the system and specific environmental conditions. |
|
| |
"Conclusion:
At a flow rate of 0.00103 liters per second, approximately 20.6 drops of water are dispensed per second." |
|
| |
That sounds like the calculation might be off, I've gotten calculations from ChatGPT that were orders of magnitude wrong, but whatever it is, we're not talking a roaring waterfall. |
|
| |
I'm thinking 3 stories tall producing about a garden hose worth of flow. But still, it's about being kind of interesting, not spectacular. |
