Storing Solar Power on my ROOF!!!
Ғылым және технология
Did you know the US state of California produces so much solar power they have to PAY other states to take it? Granted some of that is due to contracts with existing power companies. But if California had sufficient energy storage many of the state's power issues would go away almost immediately.

okay, so a typical smartphone battery holds 41,000 joules or 3 times the energy that you have here. Would you consider putting 4 more of these on your roof for science? We already know that the math checks out but perhaps this would demonstrate the efficiency superiority of water storage compared to batteries. A good science experiment would be to power a cell phone directly to this without a battery and time how long it lasts for. With your current setup you would expect it to run 3 times lessor in time with 14,000 joules then with the 41,000 joules the cell phone battery would allow. But perhaps this is enough time to power it up and make a phone call or send a text message and there is always the possibility that you can throttle down and the cell phone would still work at say 4 volts buying you more time.

Just to put into perspective, the 14.200 Joules you calculated at 2:27 are equal to 3.94 (lets round it to 4) Watts-hour of energy... That is roughly the energy stored on SINGLE alkaline AA battery (around 2.5Ah times 1.5V), or about a quarter of the energy stored on an average mobile phone li-ion battery (around 16Wh). For me is mind blowing just how SMALL is the energy stored in form of potential energy when compared to the methods we are used to every day.

There is a hydroelectric system in Central California that pumps water to the high lake, San Luis Reservoir, at night when excess power is available, then releases water through the hydro turbines to generate electricity during the day when demand is high.
Years ago I calculated that I'd need to suspend a volume of concrete that had the same square footage as my home and 9ft tall, over 35 feet in the air to have enough potential energy to power my home for a day. That quickly destroyed all ambitions I had of using potential energy as a means of energy storage.

Excellent project! I make that just under 4 watt-hours of power - enough to light your table light for four hours. There are several improvements you could make to this system. The solar panel is capable of producing a lot more energy so the excess should then be diverted to charging rechargeable batteries. The closed water system should be open to rainwater input - with overflow directed to charging batteries and further downstream being discharged to watering the garden via a planned irrigation system.

Utah Power has a "battery" that serves the grid outside of Salt Lake City. When they need it, they open it up, when power demand is small, they reverse the pump and refill the lake that is the upper battery. The scale of the tech is huge, but the basis is functionally identical. Imagine a farm getting some of its power from solar, some from wind, and some from a gravity system. Build it inside a barn, or silo, and you would not see it. I guess you can tell this excites me. I hope your children are as excited to be part of this. By the time they are ready for college, they will have such a solid grounding in the physical sciences, they will advance quickly.

It is not plausible. First the heat from sun (without focusing it) will be too low to boil it, so at best you will get miniscule amount of water. Second, adding solar panel or focal lenses to heat up the water will be plausible but this will become distillation and the water you obtain from it will be much more precious as it is very pure and can be drinkable. So, people will use this to obtain precious drinking water than to generate tiny amount of electricity (like what this video described).

Thanks for the video. I've been thinking of building off grid but I don't like batteries so I was thinking of setting up a water tower. This helped me understand how it would work and also pointed out that it's likely to be very under powered for what I need. The only major difference to my plan was that I was going to use a tesla turbine.
Awesome as always! This works exactly how a water tower does, using a pump to store potential energy in the form of water to meet peak demand- except in power instead of water
It is really informative that you were able to give us a clear figure: "( 1 barrell of stored water in the roof = 1 AA Battery. ) I always wondered what the DIY equivalent was to hydropower reservoirs. Hydropower is only usefull for home owners when they have a big land plot with streaming water. Pumping up to store energy and then release it, it's only efficient enough when talking about huge water reservoirs. Thanks for helping my curiosity.

Rather than cycle the plant, it was run close to normal capacity and the excess energy is used to pump water at night. Pretty clever.
I'm absolutely amazed that the tiny pump can actually move water to that height.

It's probably a diaphram pump. Low flow high pressure. Tipically pond pump use an open rotor centrifugal impeller. Centrifugal pumps require lots of power and lots of flow to have a decent amount of pressure.

Using lookup tables to convert 16ths and 32nds into decimal reduces the accuracy of the original measurements. But meters are already in base 10 numbering system, so you can plug the exact distance right into any formula. If I need to calculate a circle or triangle, I always use metric.

Thank you for this educational video which has the merit of showing a concrete example of the use of potential energy. Thank you also for stating that the stored energy is derisory for domestic use and for not encouraging everyone to hoist a cistern on the roof of their house to finally have less energy available than in the battery of their smartphone. Large-scale storage in a mountain lake is of course a different story....
Awesome project, a benefit for any property owner. Next comes the solar sink and steamer/condenser generator.
You explain things so well. What an awesome video and wonderful project.
Reverse the tank from vertical to horizontal with an open water trough mounted above the tank same length as the existing bbl. (1/2 of the same size bbl would work and be able to collect rain water serving like a full length funnel). When it rains and no solar available use the higher elevation head pressure from the bbl in conjunction with the exiting roof rainwater for the Pelton wheel. The addition of high with the existing low pressure nozzle should theoretically increase the rain water power generation. Additional bonus of horizontal mounting could result in 40% more storage capacity, less wind resistance, less static and dynamic roof loads as well as aesthetically being less obtrusive. I can see the high level indicator (rubber duck) now floating across the open roof top trough ...the envy of all neighbors

So weird to make an "open water trough" when most people already have access to a rain collector. The roof of their house. (And rain gutters.) Caution: collecting rain water this way may violate your local city or state ordinances. (Not even joking. Crazy, right? 😆) Probably not going to matter for any type of apocalyptic scenario, I'm sure people would have bigger worries on their mind.

Dude, love the cut-in of you chilling on the roof platform.
You could build a raincatch that feeds water into the drum in the roof. Then you get power when it's raining, and that is exactly when the solar panels don't output any power. And you could use the water to power your bathroom light so you are effectively using the water on the roof to shower and at the same time power your bathroom light while you shower :-) 3 birds with one stone.

I get power from my solar panel array, even when it's raining and very cloudy. Just a small percentage of what I get with full sun, but it is not zero. I run a 48V nominal system with 27.6KW/h of battery storage fed by 7.05KW/h of solar panels, upgradeable, (when I get enough cash saved), to 12KW/h of solar. Even with just over half of the solar I COULD use, I haven't run a generator for two years or more. I run an RV, with 2 smallish air conditioners, (as I live where it can get to 120F in summer), a refrigerator, a stand-up freezer, my computer system, and more. Learning your energy budget is maybe the hardest part of going solar. I live in an off-grid community in the Southern CA desert. I have looked into getting a 48V wind turbine, but it looks to be cheaper to just get more solar panels. As to this water energy storage idea, it looks cool, but one would need a very strong support up pretty high...and upsizing this kind of system to power a 48V system, which most of us off-gridders have gone to.

Oh, I forgot to mention that I am using LiFePO4 batteries, that can take 100% discharge, and would last around ten years at that rate, but should last much longer since I am only bringing them down to around 80% in the winters and maybe to 50% in the summers.
I love it! Thank you for sharing your ideas with us!
I'd be interested in a video testing the efficiency of your contraption and showing the math used to calculate it. On a clear day, calculate the power of the sun over the surface area of your panels to estimate the efficiency of the panels, then calculate energy required to fill barrel with solar panels, then calculate the energy generated by the pumped hydro. It shouldn't be too difficult, but could be a really informative educational video that shows how math can be applied.

Wouldn't be difficult at all, it looked like he pumped around 20g/hr up the top, using a 50w pump. I assume they are 44g drums, which means it took just over 100w/hrs to generate approx 4w/hrs in storage. So you have an efficiency loss of around 96%. One of the few renewable scenarios that works far better on large scale designs using natural and man made terrain to your advantage.

> calculate the power of the sun over the surface area of your panels to estimate the efficiency of the panels He said it's a 50W panel - and solar panels are specified by the electrical output in full sun at 90° angle (ie sun position along the normal of the panel's plane) > calculate energy required to fill barrel He said 14200J (about 4Wh), or as he stated, approximately the energy stored by a AA battery. 14200J / 50W is about 5 minutes, so given his 5.5 hour fill time he's already down to 1.5% storage efficiency for just the charge cycle. > calculate the energy generated by the pumped hydro He didn't offer any energy specs from the output of the generator during discharge, but the numbers are _already_ extremely sad even without that. Pumped hydro only makes sense on _massive_ scales, and only in specific areas where it's possible to find or build two huge dams with a large height difference between them. The Crooked Creek and Winter Ridge proposals are apparently aiming for an energy storage capacity of about 4GWh (output, estimated storage efficiency of 80% so 5GWh to fill) and a power level of 500MW, which would (each) be enough to power 8% of the state of Oregon (46.7TWh/y = 5.3GW average) for 10 hours - and that's with a pair of 2.5GL reservoirs with a height difference of 600m

Mind you, storing your water in a semi-transparent tank may cause some plant growth in the tank from the sunlight, which in turn might cause blockages in your pipe system and overall power losses! You can just paint over this tank with a white paint instead of black to reduce the water's heating, which also helps plant growth.

Maybe you are using a 19v solar panel, and the motor is rated for 12v. That's why it's getting hot.
@MrVelociraptor75
2 жыл бұрын
hmm, higher voltage should lower the amperage required to run the motor (for the same power usage). A "12v solar panel" invariably has an open-circuit voltage around the 19v mark anyway, that's normal. The excess heat is from (over) loading the pump up so much, asking it to run at maximum power for an extended period of time. For longevity, you'd usually select a pump that's over-spec for the required job. But that's not really necessary here in this vid, for demonstration purposes

Okay. Subscribed. As soon as he replayed over and over the dropping of the full water jug
1:18 The reason why the full jug was destroyed so much more was also because water is near incompressible, unlike air. That makes the jug more rigid on impact and thus the energy is dissipated on a much smaller area. Of course the increased mass is also a huge factor in the grade of destruction of the jug.

Great video, subbed! On the picture of the Swan Lake Energy Storage, I assume that there are two pipes running side-by-side, one for flowing down hill and one (probably smaller in diameter) for being pumped uphill! A tower with a small tank just to the left of the lower pond but at least ten feet higher in elevation than the rim of the second pond would reduce the energy needed to pump the water back uphill because water (and most fluids) will always find its own level! The Romans used a similar system with their aqueducts to move water across steep ravines, still works today!
