for your overflow side, why not just have the old toilet tank stopper attached to a float on a chain that will lift it up just enough to keep the gutter full but not overflow. So once the level drops back down, the float will drop and seal off the overflow.

Until it freezes and then everything that isn't flexible enough to take the expansion will burst.

@@TheLightningStalker Water in the bottom pipe will drain automatically. Water in the Siphon will either have a large pocket of air or it will have emptied from being too full. Water in the gutter can expand upwards. So where do you see this water bursting things?

@@wvance0316 Any time it freezes inside something or freezes around something and squeezes from the outside

@@TheLightningStalker interesting theory, so why would it choose to try to break things when it has the option to expand into the air. You know, the path of least resistance.

@@Dargox59 They do! Which is why it's a sign of success to be able to afford them.

@@bubblinebeeYeah, "gutters suck and can cost thousands" is just a flex to me.

There's no real need to have a valve in the system. Having a funnel as the outflow pipe make it much easier to start the siphon. The circumference of the top of the funnel can be considerably larger than the pipe it's feeding into. This effect is then compounded by the increased speed of the water entering the outflow pipe, which makes it easier to draw the slug of air along. Combined with a properly designed p-trap with a few add-ons you can get a decent size siphon to start at quite a low rate of flow. The p-trap with add-ons, if you're making it from DIY store parts would be 2 90 degree bends as the inflow, to make a 180 degree turn. That feeds into the bottom of a T-joint, with the top capped off as a small air trap. The horizontal branch of the T-joint then feeds into 2 45 degree bends so there is a small drop, which then feeds into another T-joint, placed horizontally. The second T-joint has the branching opening pointed up into an open stand pipe to vent the air. It's kinda hard to explain without a picture, but I'm sure you get the gist of it. And while not important in a prototype like this, the smaller diameter pipes in the siphon would ideally be made of brass or copper to prevent clogs from organic growth. I don't have any engineering training in this matter, but that's just my experience building ebb-and-flow hydroponics systems. The reason to use bell siphons there is that you want as few moving parts as possible. Starting a bell siphon with the low rate of flow that a pulsed geyser pump delivers, is mostly flux calculations with a wee sprinkling of black magic and voodoo.

@@fermitupoupon1754 I was thinking a funnel on the exit tube would help.

@@fermitupoupon1754 Why a P-Trap, rather than an S-Trap? The benefit of a P trap over an S trap is that the P trap maintains the water seal... but that's no a concern here, so wouldn't it be simpler to just use an S-Trap?

@@Londubh In my experience, so n=1, a p-trap has the benefit of triggering more of a flushing action. It takes a bit more to reach the critical pressure in the bell and down tube, but once that pressure is reached, the p-trap will flush and suck the slug of air with it. So it's more reliable to start, especially with a lower flow rate to start it.

@@fermitupoupon1754 but that doesn't make sense to me. The triggering of the traps is going to be purely a function of the relative heights of the top of the second curve/horizontal-ish but. Indeed, I would go so far as to assume that it would trigger faster with an S because it wouldn't require as much water to fill the top of the S compared to the (not quite) horizontal pipe of the P. Indeed, the reason we've moved to P traps is that S traps tend to "flush" the "trap" out, thereby allowing sewer gas into the house.

I legit think this is a kids channel. It doesn't take that long to explain a bell siphon unless you are explaining to kids, or people who have no functional knowledge about the physical world they live in. Practical Engineering did it way better, and much more concise. You want to confuse people? Add fucking balloons to a bell siphon explanation.

@@madscience6283 I often feel like that too trust me, but then you gotta understand this is not a registered media company with a crew and office building and studio creating content for millions of people on some national Television network with hired experts, writers, presenters and a budget. And even then they pretty much always fuck it up, and land short of perfection. Its a guy, at his house, on KZfaq. Just do what I do. Double tap right side of screen a few times. I just about got done explaining the most basic shit to partially convinced younge people like how lightyears work on a video on astronomy and cosmology in the comments section. I guess some people need those balloons. Also practical engineering is hard to watch these days. It used to be very inspired and you can tell because the content holds your attention. Then like pretty much every successful youtube channel ever created, they blow up, optimize and streamline and maximize revenue. Which is exactly what I would do if I were them but then the content is no longer inspired. Its boring! I can't watch it anymore its like reading wikipedia, but from start to finish. Listening to practical engineering is like somebody reading you a textbook on the history of engineering whilst you're tucked in bed, as he interjects here and there with a clarification or two, before suddenly and without warning he reaches in his pocket and without breaking stride pies you right in the fucking face with a buttload of advanced maths (atleast the me). We didn't all do math and engineering after highschool. Some of us didn't even finish highschool. I suppose wikipedia does that too. But there it fits. The maths thing is kinda ridiculous. Its like saying halfway through, "oh btw I forgot to mention this video is for people who know calculus and went to college, sorry about the rest of you. And im not even saying I never ever understand the maths part. Just almost never. Edit: sorry I mixed up practical engineering with real engineering. All good channels though

Not sure, the explanation works with three concepts, communicating vessels (can work within limits in near vacuum), siphons (can also work within limits in near vacuum) and pressurized systems ( like here a siphon with an air pocket) . I had to check internet to get the explanation right, as one idea doesn't explain the others. The plus is by checking internet I learned something. (edit the () parts)

Yup, I think that's the best solution.

Weir were you earlier?

@@QuintBUILDs Should be able to do it on your other gutter outlet. I would think a collar around it with the height you want for overflow, then if you want to help keep debris out of it, you could just put a cap over it. For the other issue with the dribble, I thought maybe a tipping weir might work. Basically making a dam that has a section (L shape) that would tip over when the height of the water overcame the weight of the section. When the section tips over, the lower section would be 'pushed' by the flowing water keeping the top section down, then when the flow decreases, the lower section drops back down and holds the dam closed. You can adjust the weight of the lower section to meet the minimum and maximum flow.

@@TheCapt I think it would be easier to use differential mathematics to describe the dynamic system to then engineer a pump, hose and valve system that measures pressure, water height and maybe flow to determine via a PID-Loop how much water to pump off to never have any overflow at all! I hope you understood the joke in this, I liked your enthusiasm in wanting to find a solution to this problem mechanically or better said ... failsafe without any extra energy needed to be put into the system.

Solution too simple, not enough clickbait

@Jesus is LORD hail Satan

Said the same. More than one siphon. Oughta handle all that water..

Small diameter siphon outlet for light rain. Larger for heavy.

Add in parallel, more water means more generators. Faster charging or multiple battery charge.

Or a weir at the oveflow...

Don't even need two bells, 3 pipes in one bell. Use thick input and then a thin output for the generator and a thick output a bit higher for proper overflow!

With higher flow rate at a higher trigger height maybe

Or add a reservoir at the overflow which dumps its contents when the flow into the overflow stops. Additionally you can add a small foam float valve on the intake to the syphon which gets buoyant once the water gets high enough. This should trigger a more sudden inrush, triggering the syphon to waste less trickle.

@@wilcoslegers8281 yea he could just fill a rain barrel with the runoff and open the hose on dry days to fill the main reservoir again and re-collect the water in the rain barrel again XD OMFG i think i might be an evil genius

I was kinda thinking about a bucket filling with water, then tipping when full to give a powerful rush of water

I am saved by turning to Christ in repentence and faith.

literally my thoughts exactly.

I was going to suggest the same thing but have the second higher level one siphoning to a reservoir lower than the gutter but higher than the pump for use when the rain slows down.

Sure felt like it this time... but the response to the video is much improved!

Editing is not easy.

@QuintBUILDS thank you for the video man!

@@QuintBUILDs I got it in my recommended videos, had no idea what to expect and really enjoyed it, even though I have no use for this

My thoughts too. Perhaps even adding it to the same wheel but have it at a 90 degree angle from the other. Perhaps that makes it sound faster?

If he did the math he could figure out total possible volume of water per minute for his roof during highest record rainfall and then know if he needed 1 or more extra downspouts with generators attached to each. But he might have to stagger the hights to prevent too high of a total threshold to start all the bell siphon if they were all at the same level during a slow rainfall. But he could test to confirm in next video :)

My thought almost exactly tony

That sounds more like science than engineering. Engineers are supposed to simplify and keep things cost effective. If the first turbine is properly sized to max payback, it is not likely that the second would ever pay for itself as it would not be used as much as the first.

Just put an accurately dimensioned barrier near the second drain: with low rain all the water will be used in the turbine; with heavy rain the excess water will overflow!

I'm glad! It was tougher than anticipated! 😁

I can imagine that it’s not electronic 🙃

I think a 1/48 (1 inch every 48 inches) cone is unnecessary, a 1/5 is also ok

Agreed,i think is gonna make more power

That’s what I should have done on my raised flower bed 80# manufactured decorative bricks. After very carefully leveling a couple at a time, after 50’ when I came back to meet the ends, I was an inch off and is noticeable. Looks great overall though. Many practical uses.

Those hose levels are good for short spans to level, the lazer level does not bow with the curbature of the earth. The hose level will take you around the world and the lazer level will shoot you out into space.

Yep, just keep in mind that if there is wind it could potentially push into one end of the tube, increasing pressure, and possibly even "pull" air out on the other end (Bernoulli's principle), decreasing pressure. That would affect the water level on both sides.

@@nelsonrothermel you will notice it moving a lot if wind blows in that strong. Just wait for it to settle out and you can always put your hand around it if the wind is that bad

Sounds like you had just as much fun in college as I did 😂😂😂

agreed @Quint BUILDs

I was thinking the same thing.

Yes, also the siphon starting height is limited by the max gutter height. So the waterwheel bell siphon needs to be lowered so it could start earlier than the high throughout siphon. Testing would be a little annoying, can easily test each side of the system separately for functionality, but proving the system as a whole may require another heavy rain.

Would have to lower current one and add max one. Giving you high and low rainfall. May need to look at max rainfall per hr and roof area to size it to match worst conditions.

He could probably solve it easier by just widening the tubes. Or putting a nice rounded edge to increase flow rate.

I believe the name "bell" is a reference to it's shape and not a person but the mechanism found in Pythagorean cups are exactly the same mechanism.

Its only a Pythagorean cup if its from the Pythagoras region of France.

That does seem a brilliant idea. Or, for the sake of keeping it simple, notch out the gutter at the top, on the end or the front - then attach a downspout at that notch, so that any excess water just flows away, and doesn't rely on any systems which could fail, become easily blocked, or be overwhelmed.

I had another, even easier thought. At the other downspout, which is currently blocked off, extend the outlet up, so that it is below the top of the gutter, and at the top of the max water level you want to hold - job done.
