Water Pump Without Electricity - Robert Boyle's Perpetual Flask

Perpetual Motion of Water - Robert Boyle's Perpetual Flask - One of the most curious inventions of Robert Boyle, is known as the Perpetual Flowing Vessel, or Self-Flowing Vessel.
The principle is quite simple: the weight of the liquid in the vessel is significantly higher than the weight of the liquid contained in the neck of the vessel, this causes a pressure difference which causes the water to rise up the neck of the vessel. Thus, the liquid is forced to flow in order to compensate for the difference in weights (hydrostatic pressures). If this compensation is sufficient to raise the liquid from the neck to the upper zone where the tube ends, the system acquires a continuous behavior to compensate for pressure differences.
Unfortunately the theoretical foundation is wrong because it confuses weight with pressure, and therefore this would never work.

I'm very glad that you are showing people how the scam are done. I think it's sad that anyone is trying to scam others like this. Thumbs up for this!

[shaaltear]

nice idea, was thinking the same thing. but what if you make the hole more smaller and make the water holder more bigger, will it make a difference. like make the straw thing very very small.

took about 5 seconds to realize this was not possible water seeps it's own level, I just built a water level to set the piers for a gazebo

For the doubters:
My wife has a perpertual motion mouth that never stops nagging. She must have inherited that mitocondrial gene from her mother (which would be my mother in law).

I see a lot of people saying it’s impossible and to those people I said no duh if you watched the video beyond one minute you would know 1:24

[ludi]

Though Perpetual Motion Devices don’t exist, shouldn’t the potential energy introduced into the system when dumping in water from a higher point allow it to run for a while? How long can this realistically be? I imagine the frictions (such as creation of drops at the output) to be extremely small!

[JasonECI]

Haha, your video is almost 4 min long, but over 90% watched only the first min to conclude. Great video!

[justinscrazyworldTV]

I spent 3 minutes and 50 seconds watching the video and then spent 30 minutes reading the comments 🤣

Так вроде у Бойля стеклянный сосуд был ( если не путаю), и конусность плавно поднималась в вверх, в чем и был секрет .( Я в курсе о сообщающихся сосудах ) .фокус был в раствореном в жидкости газе который и был топливом ( вариант примитивного эрлифа ), цвет и вязкость жидкости подбирались с целью скрыть пузырьки поднимающихся газов .( По газу, варианты азот, водород ) .
Могу ошибаться.

If it was beer we might find it interesting.

[areyouavinalaff]

oh it's a trick. I thought the flow looked a bit low for the bore of tube shown. makes sense when you reveal the bore of the actual donor tube.

[DantePlans]

What ive never seen been tried before is the same thing but the tube is connected higher up and its way shorter, with this liquid that should work? Idk someone should try it

[andreadelprincipe]

Very well explained. You are Great. Many people will think that the device actually work but you say that there is a trick to deceive them.

Отличный фокус.И главное, что физика и её законы торжествуют.

Fact: Using the word “machine” with perpetual motion or energy, will give it a beginning
and an end, making it finite.  With this new and better understanding of perpetual devices, its meaning will need
updating in defining it as finite.  This way, these devices or machines will not violate the laws of thermodynamics,
laws of nature, laws of physics, makes them patentable.  ~Guadalupe Guerra

Como podría calcular la entropía de entrada y salida del flujo, de esto

[michaelz]

Back in the 90s as a teen thought of the concept of the Toyota Prius. A vehicle that uses a battery that regenerates it's energy. Also, the concept of the drone... Except thought of the smaller version and big enough to carry at least 2 people.

But one concept of which I have not yet drawn or written on paper is a perpetual machine with water. But I'm not going to divulge my secret on the internet. Ever.

[juliana.rilveria]

Water having greater density you wouldn't be able to do this... now since this liquid is less denser the force of gravity plus water pressure from falling and slightly builds that pressure for it to be possible to cycle mechanically free with using a hand pump or an electrical pump.
But really cool and not fish friendly...

[laxmiagrawal]

We can use them in wash basins, just put a filter in between and then put the setup
It will save much water

[peacelilly]

So how much more weight would be needed, to add the pressure needed?
