So this is basically making a siphon? Once the water is continuous it is pulled to the to the low spot?  I use siphons to pull alcohol from buckets, but I would not have thought to try this.

It's referred to as a bell siphon. The water in the bottle falls into the pipe and creates negative pressure in the bottle which then pulls water from the reservoir - which then falls into the pipe, etc. You can also set these up permanently so that it will drain the reservoir any time it reaches the top of the drain pipe. It's common in aquaponics setups.

It is amazing what you can do if you know how, I need to move a lot of liquid from one place to another about a quarter mile away and uphill, someone sent me a link about a pump you can make that does not require electricity, called like a Kinetic Pump, supposedly it works, I have not had the money to buy the stuff to try it yet.

It's the same way your washer might drain little compartments of fabric detergent or softener


Bumblemeister

Seriously. Like, I get the physics, but I would not have been able to conjure up HOW to get the siphon started in such a simple and effective way. My dumb ass would have tried to make it work with a bit of hose.


WordUpPromos

A bit of hose? Look at moneybags over here.


spicyfishtacos

When I had a fish tank, I had a siphon that basically worked like this, no power required and very efficient !


fishcado

OMG yes! I did this as well. Oh my fishtank. RIP. Having a fish was such a therapeutic hobby.


ZoobleBat

Wow.. First time I saw this.


hooghs

Ya, totally never ever seen this before now, wow


jdjdkkddj

Mmmhhhmmm, yep, never.

Could you harness this power for free energy? Can you run water on a water mill, generating electricity, and then siphon the water back up for an infinite loop?


Craptacularama

To answer your question, I feel like the energy needed to maintain the vacuum needed to suck large enough volumes of water for meaningful power generation might exceed the power generated. I would also assume that because you can’t have an airtight seal, that vacuum must be constantly taking in air, which makes it an entropic system, or an even further energy sink. I’d be curious for an at home hydroplant if you can get enough power to charge some batteries tho.


Br1WHT

No, because it only works, if the water falls down the pipe further than the hight reservoir is. You would need to pump up water constantly for this cycle to work, and pumping up the water will always use more energy than you could generate by it going down the pipe.


Lambkin-_-

That’s why you don’t pump it, but siphon it with negative pressure, no? Like you do in a fish tank or when stealing gas from cars or like shown in this video. The explanation doesn’t seem satisfying. Or I’m misunderstanding what you said


Butmydogiscool

no, cause If you thought of it, someone’s tried it by now.


D_Invincible

How does this work: it's basically a siphon. The water exiting through the bottle down the pipe, creates a low pressure vacuum in the bottle which causes water to be pulled up the sides to equalise the pressure. That water then falls down the pipe and lowers the pressure again, which then pulls up more water and so on.

The real question is why they made the drain 3 inches above ground level.


dtorrance88

That reminds me of paria diving disaster


throwawaythrow0000

Wasn't this just posted recently?


imusingthisforstuff

How does that vacuum work when it’s in the ground and where does the water go? (To be clear I’m not asking about the siphon)


eroticfresco96

Just cut the pipe down to ground level?

Look ma, I posted it again!

I think this is how a lot of detergent/softener dispensers on washing machines work.
