Heron's Fountain is a mind bending hydrodynamic mechanism. It appears to be perpetual motion but it fact it's a really clever mix of pneumatics and hydraulics. This 2D presentation helps to explain how it works.

The object itself is 3D of course, but there's nothing interesting happening in one of those dimensions! What I'm saying is, there's a legitimate sense in which the mechanism is 2D. Don't @ me.

Not something that would work in 2d, but I have noticed lately that lightly stirring (in a repeated pattern,) the water in a pot that's just starting to boil is a neat way of 'seeing' the currents. If you time it where bubbles are forming on the bottom, but not rising yet, because the water above them is still cool enough to act as a condenser, then when you stir, the faster moving currents will carry the heat away from the part of the pot under them faster than the slower moving ones, so you get lines of bubbles where the water is more still, and the heat can build up more. I don't know if there's enough there for a video, but I definitely thought of you when I noticed it.

I remember seeing (and using) the German toilets when I went on tour there with a band in 1984. The sound engineer's theory was that it reduces the incidence of piles because people spend less time on the toilet (find somewhere else to read the paper) and the vocalist's theory was that it was so that you could look at what you had produced and have a greater chance of finding any indicators of bowel cancer (or other disease) there - they eat a lot of meat there. I also recall the same feeling of horror that you did when you see the fill-up-then-empty type. So, what to take away from this comment? If you want to see the toilets of the world, join a band and tour ;-)

I have built many Heron's fountains, for my children and for my students, using bottles. But I always much separated (a quarter or half a metre) the two bottom bottles, used long pipes with long visible lengths outside them, and topped the top end of the uppermost pipe with a strainer. Results: • The fountain had a surprisingly tall jet, reaching very high over the pile. • Water circulation through the pipes was very visible, at least if some air bubbles were present. Once the top pile is empty of water, just putting the artefact upside down empties the bottom bottle into the upper one, and the fountain is ready to work again once returned to its normal attitude.

Uk usually aligns with Australia RE plumbing supplies, we have flushomatics if you want to go into some hydrodynamics seen in our toilets. They seemed cool to me, but it was part of my carrer, so that might have helped. Basically the valve breaks an air lock which alows a certain amount of water to pass and flush the toilet, then the airlocked equilibrium comes back and the flow stops again, giving you a flush that doesnt need time to refill between uses, which is ideal for public toilets. The valves are also mostly recyclable, the seals will need changing every so many years, but basically its a similar system to gas bottles, you trade an old leaking one for a refurbished valve, they refurbish yours and trade it on to someone else, you dont pay for a whole new valve, and the majority of it lasts decades before actually becoming waste.

What you need here is a trompe, straws/tubes reaching almost the bottom of the left waterfall tube but sticking out ABOVE the water level above (in the model version that is,) otherwise you dig a shaft 300 feet long and just use short straws in a funnel shape with a stream above forcing the air BUBBLES downwards in the funnel then tube along with the higher pressure water, and a chamber after a right turn at the bottom, culminating in a chamber of COMPRESSED AIR and water going to another tube to almost the height of the stream but a little further along downhill. This compressed air can be used to drive air driven MACHINERY, fill tanks to run vehicles with steam engines running on just air pressure not steam, or run into a building to create a massive refrigerated room. Getting back to the model version here, the tube would NEED to be very low in the tank to allow the air to be forced by the water pressure above, to the right giving more AIR into the system to keep it going.... erm for how long who knows? ;) You'd definitely need more water here... Not sure the tube width changes or actual depth required down the waterfall area but I'm sure SOMEONE will give it a whirl :P

You gave me an idea to use this principle for my cat's drinking fountain (cats love fresh, moving water). So I'll give you an idea for a video: Water locks with water saving basins. I'll refer you to look up how the Panama Channel water saving basins work. Water locks may be simple in principle, but Water is such an important resource for the Panama channel they invested billions into water saving basins that save up to 60% of the water used per crossing. Because if it rains too little or they use up too much water, the depth of the cannal may render it impassable for shipping. The way they work is that when a boat has to be lowered, instead of discharging the lock's water into the lower level of the waterway, it instead drains into a separate basin that is at a higher level than the lower channel. The water level at the lock and the basin will level off, at that point the valve between the lock and the basin is closed and the rest of the water has to drain into the lower level of the waterway. When a ship has to be raised, the water from the basin drains into the lock, then the basin valve is closed and the lock fills the rest of the way with water from the higher level. A one basin design can save roughly 20-25% of water (it depends on the area covered by the basin). Panama channel uses 3 basins per lock. each at one height. When one levels off, the valve closes and the next one gets filled and so on. It's a really simple and clever piece of engineering. And I've made one in Algodoo, so I can definitelly tell you it can be made as one of your models. Also, just for curiosity's sake, I calculated how much each cubic meter of water costs to be moved on the panama channel based on how much water is drained and the cost of traversing the whole thing. They charge $60 dollars per empty 20 foot container and $90 for each full container. The largest Panamax class ships can carry 15000 20 foot containers, so based on that, the height of the cannal and the size of the locks (there are six and they're all the same size), I calculated that each cubic meter of water in the panama channel costs between $0.16 and $0.25 if we don't take into acount the water saving or $0.40 to $0.60 if we do. Where I live, the cost per cubic meter of treated tap water is roughly $1.

the heron fountain looks like a good example of a potential energy battery. you pour liquid at the top, essentially adding mass with high potential energy and it pushes the fluid in the middle into the bottom reservoir. so the amount of potential energy u can store is whatever the amount is in the middle reservoir and the depth is the distance between the middle and bottom reservoir. i dont know how this will work out if upscaled due to friction, surface tension, bubbling etc but it feels like you can fill the middle reservoir as to fill up the system with potential energy, start it with a small amount of potential energy by filling up the top reservoir, and harness the flow of liquid coming from the middle reservoir to the top reservoir
