Storing Solar Power on my ROOF!!!

- 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.

Awesome project! I've been thinking about something like this for ages. Have you considered using capillary action to move the water up and then send it back down into the reservoir when generating power with it?
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.
@@TheBowersj I like where your head is at. I'd need to dramatically increase the efficiency of my generator first. I think I was only getting 40% from the rain gutter!
You know... if you replaced the water with mercury, you'd have the equivalent of *14* AA batteries! :grin:
Bit of an issue in earthquake country. Maybe add a quick release for all that water if a quake is detected? :)
I can imagine the neighbors. “He’s up on the roof again!”
Yeah Mrs Kravits
They already say that... I don't have solar yet...
Lol!
He is a neighbor I want. I would be is humble apprentice.
lol but its so cool, so much low hanging eco-fruit
In Scotland UK, there is a hydro-electric dam,when there is excess wind production off the coast (too much for the grid to handle) water is pumped from the lake at the bottom to the top, to be released when extra power is needed, it is then released through dam.
Something similar in Switzerland as well. Very cool. Very very very cool!
yeah pumped hydroelectricity is actually pretty common in Europe and there are GWh of storage in this type of device
What is the performance of these kind of thing? How much energy is used and how much it generates?
@@augustoaAbout 80% efficiency, sometimes higher, so pretty decent, but not perfect
@@weir9996 80% is decent, depending on how long you are storing it can be better than regular batteries. Thanks for replying!
The tiny pipe is restricting flow and potential for pressure. Normally for microhydro we need to jet the water out to increase impact on the impeller. We also start with larger pipes and funnel down to smaller pipes. Also we will use up to 4 nozzles on the impeller, so a larger pipe splitting off to the 4 jets.
You could just use a venturi system with 1 pipe? Keep quiet
@@no-knot9567 multiple nozzles help reduce wear on the equipment by dividing the velocity between more than one nozzle.
kind of where my mind was at. I was pretty sure you could get a lot more juice out of that barrel, with enough pressure. I saw a few old turbine systems which ran with PVC off a river that wasnt going that quickly and they generated enough power off that system and river for a small neighborhood.
There's not much point to any of it though. A tonne of water will only provide 100 watts for say 1½ minutes sitting on roof. More if it's hundred metres high of course.
@@philip5940I guess it would be be best if near a water source and simply pumping up hill
I cannot express to you how much I appreciate your fax paws.. trials and errors, troubleshooting... obstacles and learning from this!!! And involving your children in the education, I love it I love it💜💜💜💜 TY
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.
It's amazing that a single AA battery can power the pump long or hard enough to lift this amount of water 7 meters high.
And you did not even count the *huge* amount of energy already needed to build this setup, or the one the owner will need to spend, for maintaining it.
And that's only calculating the amount of potential energy stored, not how much energy it's going to take to pump it up there, since no pump is 100% efficient, nor how much of that potential energy is going to be wasted when you try to covert it back to electricity, because no water turbine is 100% efficient.
this project is an incredible waste of time.
Pumped hydro energy storage schemes are the last desperate ploys of the environmentalist politicians and their bureaucrats.
Also its near to muzzle energy of .50 cal bullet
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.
Your expectations were low and your ambitions not strong enough.
It is not doable by most people, but for those who have the space and slope to make a water reservoir for energy storage, it by no means destroys their dreams.
The cost and space involved usually pay-off for those with more cash and land in their possession, especially for a government.
@@UserName-cb6jz The vast majority of people with the land and cash who wish to have energy storage will still opt for $300/kW-hr batteries over potential energy storage and use their two ponds/reservoirs for fish, and not risk liability of hundreds of tons of solid material suspended or on a grade.
there's always the flywheel, have you looked into any of the commercial models that are already available?
use sand
Thanks, apparently someone was needed to point out how terribly inefficient potential energy is, because people here simply choose to believe what they want.
Would be cool to see a series where these concepts are put into real life use in say an off grid living environment, aka a cabin homestead.
It would still require a lake on top of a hill and a lake down the hill to power your house through the night.
For example if you have one lake that's 50m*50m*5m(or around 5 Olympic swimming pools) and the same lake(or another 5 pools) on a 30m hill(the height of a 10 story building), *assuming perfect efficiency*, you'd have a battery with a WHOAPPING 1kWh capacity. That's one, medium sized car battery 😐.
There are tons of DIY hydropower videos
USA is special ig, in many many countries we have overhead water tanks. They provide water to all the house without requiring any motor.
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.
I enjoyed this immensely; thank you for putting the time in to educate on this topic in such an entertaining way, I love how you tied this to future and existing grid storage! The cloaking device was really neat too!
This is brilliant!
I love to see a father teaching his passion to his kids.
Keep up the good work!
This is a kind of teacher we need in schools not this woke bulk crap we got now that is completely useless and detrimental
I thought the same, that's fantastic!!
We already have this, it's called hydro energy. The green types are currently trying to get it destroyed because they say the same destroy ecology.
@@ouiroc they are too busy trying to figure out which of the 50+ genders their students are

That was really cool! Thank you!
Wow, thank YOU Zack! 👍
2:58: Man says to his daughter how far she can squirt.
Lets zack rig it!! Hahaha
@@QuintBUILDs I love what you're doing and I have been following it for a while now and I must say that while you have done incredibly well I think you can actually get more power than you even realize out of your water system...
Your pelton wheel setup has a fair amount of efficiency.
Some say the Tesla turbine is more efficient or is it?
Could you print up a Tesla turbine on your 3D printer and then hook it up to see if it could spin your little generator faster and produce more voltage?
It's not cool, it's really hot!
This is awesome, I love videos like this, no matter how little the energy result is it’s still amazing to learn about mechanical design and what not, thanks for the video!
This is incredible. You are a fantastic teacher, really inspiring stuff. Thank you. Now to watch some more.
What a superb example of how to do an educational UA-cam video. No messing about, straight into the build with no patronising despite explaining everything clearly. Best of all, you didn't use 10 words where 1 word would do! Makes for great watching, thank you!
thanks you for sacrificing your own home for our education 🙏
Wtf! What sacrifice
This is absolutely incredible! Well done.
Great project! Future thinking for sure. Canary Islands tried something like this at scale years ago. Continuous power with renewable is so practical
Blimey, fair play to that little pump, producing >5m head.
The narrow pipe inner diameter lowers the weight of the 5m 'water pillar' the pump needs to lift. May be wrong, but that's how I see it.
@@ifluro That affects flow-rate, not pressure, IIRC.
This would probably be helpful (I CBA to go through and check everything again currently). Practical Engineering channel - ua-cam.com/video/ZQKpu-obzlU/v-deo.html
@@ChrispyNut @ifluro is right (but there’s a catch). The force is proportional to the area of the cross section of the tube. So at a 5m head you have about 0.5 atm of pressure, if you multiply it by the area (set’s say 25 mm2) you will have a 127 grams force at the end of the tube. But this doesn’t take account where the actual force is applied which is on the “blades” of the pump, where the same area theory applies. So you could have a super large tube it still wouldn’t matter since the force would be on the small pump, so again, small area = small force.
@@ifluro The amount of force is strictly determined by the area of the pumping surface. The tube shape makes no difference.
heyy fellow intp
I think it'd be interesting to try and pump 55 gallons up to your roof using a single AA.
Yikes hehe
I think it would work. But only for a little…maybe a fourth of the way? The solar panel may have the same amount of power as the battery but can last as long as the sun is out. So, still would be interesting though!
@@ezrarichardson279 I agree, you would need a very efficient pump and something like a very efficient joule thief, and even then you'd still probably only get about halfway there due to things like friction in the hose and pump.
18650 would be able to do it. LiFePO4 battery would be able to do it for ten years every day.
its only efficient when using huge amount of water to turn on a 1000w motor
This video was so bloody wholesome, feeding your kids knowledge and getting them excited about physics and experimental sciences is absolutely awesome. Definitely just subscribed and liked
That was a fun and fascinating way to learn a little something I never thought of. Perfect for young, curious minds (and old ones like mine). Keep up the great work!
You are an AMAZING Dad to involve your children in your science experiments. This is how you create little scientists which will change their lives (for the better) forever. Great job, dude.
That is the most interesting part for me. It is awesome
Somewhere he needs to teach his kids to think. He's gone to great trouble to solve a problem. If he did the math he could show them it's not worth solving. They say you can't fix stupid. I disagree. If you can create stupid (i.e. teach it), you can fix it.
@@toddmarshall7573 Do yourself a favor and DON'T become a father, creep.
*little discerning thinkers
The project would be worth doing if only to involve the kids in a learning / thinking experiment that they could enjoy with their dad.
Too many so called parents don't spend time with their children, much less take time to teach their kids something useful. Which is why we see so many single parent (ignored or forgotten) kids turn into criminals, as opposed to kids with both parents in the home succeed in the very same neighborhoods.
Lol I love how you said “look at all this energy” that is such a nerd thing to say. I’m right with you too
Love your vids
Nerds Unite! 💪🏽😎👍🏽
15:00 is the best explanation. for that a milion thanx :)
Love it! Enjoyable and fun learning. Well done Sir.
One thing you will start noticing soon is the algae build-up in the recycled water system from the sunlight. You can go to a pet store and get some algicide or similar to add to the reservoirs. This will kill your pump in short order.
The algae or the algacide?
@@johannesmajamaki2626 Yes sorry, that is confusing, the algae will damage the pump by reducing flow and increasing friction.
Could always paint the barrel/tubes
You could use a blue pond water dye to Help block the light from penetrating the water in the tubing and drum which slows down algae growth since it’s a closed system.
He'll probably want an antifreeze in there as well.
A fun and educational experiment! To help people make more comparisons, it might be useful to note that the 14,000 joules is about 4 watt hours, and that's about a third the capacity of an iPhone 13 battery.
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.
9:12 your desk looks exactly as it should, if your desk ain’t a mess you ain’t the best.
I like this guy! I’m thinking if I were his kid, growing up with him how much fun and interesting my life would be. He probably knows deep down the example he’s setting , but even moreso he’s a “doer” and the benefit for his kids is great! Imagine the stories his kids will tell about their Dad to their kids… lol.
I totally agree, but there is no such thing as a perfect dad. There will be a point when everyone at home starts wishing they had a normal dad who buys a regular water pump like everyone else, someone who can provide some good stock advice to the kids, sits around with the family and have casual conversations about regular stuff which makes the wife feel that he actually cares more for the family than his stupid science experiments all the time. 🍷🤷🏻♀️
He can be both! My mother is like this! I don’t want her to be “normal”! And my gf is not “normal”, she is painting and also telling awesome jokes, and also working and blushing like a child. I really don’t know what you mean by getting a normal pump, well you can buy everything you want nowadays, even a tank or an airplane. It just does not make sense for me to renounce your hobby to make your kids feel like “normal” ones. Well, they can be normal - play videogames, go to gym, fart like elephants, eat pop-corn and listen to funk or whatever is popular, why can’t they do that because of my hobby??
Just to get a better understanding of how much energy that is. Whould you please drop that barrel of the roof. That would help my understanding a little more.
Ha ha!
Fun show! Look at the Smith Mountain Project... that is where I live. its a very cool water battery that has been operating since the 60's ;) ML and Blessings all! 💪❤🙏💯
I love it! Thank you for sharing your ideas with us!
That aluminum tab on the top of the barrel also makes a nice little lightning rod.
Meh, it's not well grounded, so not as great at attracting lightning as it could be.
I first saw metal on the barrel, I thought he was making a 55 gallon liquid rechargable battery. Even better if it could attract Static charge from a ground.
It's great that you involve your children and evoke their imaginations/interest in science and practical skills 😀
Kids would be loving it
I think it's great that you get your kids involved. Great share.
Love the desk/workbench shot. Controlled chaos.
Tip from an electrician/outdoor climber. Install climbing anchor so you can tie in to a harness! So any time you go up there you can tie in before working.
The wonderful thing about metric, is that you can easily calculate the necessary pump by taking how much water it needs to pump, (the joules), when you want it done (the time). Giving you around what you need.
All without a ridiculous cheat-sheet for converting gallons per hour into horse power.
🥛 ⌚ 🐎
and the bad thing about it is that it teaches you to think in multiples of 10 and nothing else, so you're at a disadvantage for anything but round numbers
@@kingmasterlord I've often thought about how imperial's weird fractional measurements might make you more math savvy. But that's only true if you use them a lot, if you're just wanting to do a quick calculation, you might just give up.
@@kingmasterlord with all due respect, but that was an almost worst defense of the imperial system than "it's been used for a very very long time"...
@@rhobson I made no mention of the imperial system. your thinking is rigid and binary.
case in point.
You explain things so well. What an awesome video and wonderful project.
I actually thinking of a topic for my thesis now.. thank you for giving me additional idea
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's really more disappointing than anything. We haven't been able to make a shits worth of power without water for over a 100 years, and instead of investing in the next generation of power generating technology we waste our money on extremely inefficient, unreliable, expensive, solar and wind.
Huge one exists in South Carolina. Has for decades.

I measure temperature in bald eagles and distance in meters
I'm glad you're so "cool" with your government-imposed metric system.
@@hg2. Imperial measurement systems were taught to me in school, but I choose to use metric for woodworking. 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.
@@Alkatross
Good for you.
Your social expression about it is obnoxious.
Thanks for sharing. I had this same concept in my head a couple days ago.
Thank you! Wonderful and edifying. Also great you had your children participate.
Same kind of idea i have had. Like having a water tower. Or look at what they are doing in switzerland. They are using solar and wind to pull concrete barrels high in the air then at night they slowly go down turning a generator. Really awesome form of mechanically stored energy
Or dig a hole for it to drop into for added capacity.
I love how you bring your family into your experiments and builds! Your kids are going to remember this for a lifetime :)
They will and their children's children will be able to experience this aswell because the battery should last a very very long time!
Clever video, great demonstration!

Please don't stop this series, it's just so awesome. You are making must of my ideas come back to life but giving a proof and awesome explanation that I could've never done
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.
was not in anyway a permanent structure.
Go to the dollar store and get a bunch of copper scrub pads. The copper will kill, or should at least discourage bacterial and fungal growth
@@Mars-zgblbl What do you mean? Can I put this on a cat water bowl? I give water to stray cats but the bowl is always getting green stuff in it, do you think putting those things will avoid that?
@@theblukatlife Yeah, copper coins in the bowl can also reduce the algae growth. You should still replace the water every now and again though.
There's zero chance he is using this thing beyond making this video. Cool idea, but it's worthless.
In Germany we have such water storage facilitys, we pump it up a hill and get the energy
love this little build, I would love it more to see you research and improve this as far as you can take it while still keeping to the DIY nature of it all. I would love to see some efficiency calculations and numbers on watt hours your current system holds
This is tech I've known about for a while, but it's cool to see someone actually make a working version as a demonstration. This earned the channel a sub.
Yep. They do this with hydroelectric dams and nearby wind/solar plants and this demonstration shows exactly how efficient it can be
I don’t know if this would work where I live in Vermont. A gallon of water here is only like eight pounds, and he has water that weighs in kilograms! I mean eight pounds is way more than a box of honey grams but it’s nowhere near a thousand of ‘em
@@fishhuntadventure well being sarcastic is great, however in 99% of the world 1L water is 1000g/1kg
Been using it for decades near me with conventional power sources. Excess grid power at non peak times pumps water to a reservoir on a hill, when power is needed it is used in a hydro generator.
And another sub here 👍
You have a real gift for explaining complicated things in a manner that we can all understand! Thanks - much appreciated…
There's an entire power station in Scotland set up like this. Two dams with massive pumps and a hydro turbine.

Dude, love the cut-in of you chilling on the roof platform.
Please do more of these solar projects. They are amazing!
Great idea! Very hands on
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!
Great video, here in California in 1984 the Helms Project started producing electricity, water pump from a lower lake Wishon using Nuclear Power from Diablo Nuclear Power Plant into Courtright Resevior, then released back into Wishon producing hydroelectric power at Wishon.
Also, you can use the pressure as a feedback mechanism to cut off the pump when full (no need to run wires), the float switch can just close the hose and a pressure switch at the bottom can turn it off electrically 🙂
A ball cock system as used in a flush toilet would close off the tank feed.
Science rite up in heer!
More efficient to warm up this amount of water. We get then around 230 Wh per just 1 degree of temperature, that is 50 AA batteries. A huge difference.
Just found your channel. Fantastic project. Will be looking through your back catalog for sure
Thank you! Great job of doing science with your kids! Engaging their natural curiosity,experience and questions. So much better than just teacher/ authority demonstrating! Good thinking family man scientist
Sooo much educational info in this video! Now I know why we get a power bill. Paying for what we use.
The fun facts were cool, when you were using items from past videos.
The varying brightness of the porch lights were a great way to show the measurement of the different levels of a watt.
Thanks for all of the man hours you must have put into this video. Great job! Fun to see the kids included in it, too!
I actually learned something today. Thank you.
I had this idea on how to store my energy from my solar panel just be imitating a big water kraftwerk. And its nice to found that someone actually made it! Great!
I'm absolutely amazed that the tiny pump can actually move water to that height.
I concur. Pond and fountain pumps can barely do 8 feet
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.

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.
Don't talk, do it!
It's clear that your real motivation is . . to make all neighbor squint with envy 😄

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
very inspiring, I think I've better understood the meaning of power/watt today, the way you're explaining it with water and valve was very intuitive. thanks)
You could also look at the efficiency of your energy generation system i.e. an enclosed water wheel would help by keeping the weight of the water activly working and friction on the shaft may affect the system quite substantially.
Love this experiment and the custom elegant fixes you made along the way!!! Awesome way to explain science and propose energy storage improvements. You rock!
Wow, thank you for taking the time to do this show, it's absolutely fantastic.
Love your enthusiasm
You could supplement the solar pump by adding a ram pump from a nearby water source. Could help for cloudy days, plus would be adding water all night too.
I love your videos and the fact that you use them to engage your kids in practical applications of science and engineering. You seem like you would have been the coolest Dad to have growing up.
Quint -- You should explore misting that water over your roof in the summer to see if evaporative cooling could help lower your power bill... then collecting the left over through your gutter system... perhaps you could get more 'work' done by linking a few systems together.
problem is the water would probably cost more than the electricity saved plus wear and tear on the roof shortening its lifespan.
This is great, love a different perspective. Not sure if you've addressed it since I'm only 1/3 of the way through, but a totally opaque barrel would be useful to avoid some algae bloom.
Love this water battery! Cool job!
Loved it. Wish we had you as our professor in Engineering school.
I have been watching the Swan Lake project with bated breath. As another Oregonian, I've always appreciated the work they've put into renewable energy. We have a long way to go, but I'm happy to see the progress
I am really impressed with your unique idea🎉

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.
I have been imaging about this for a longtime but I didn't know how to start it. You are the best experimental man. Thanks for shared it.
I like to imagine the reaction of Mrs. BUILDs when you told her you were going to put a 50-gallon jug on the roof.
wonder what the neighbors thought as well when they saw that little addition.
no doubt she made him remove it after the video was recorded
Or the local code enforcement folks...if you don't fit into their "mold" you are WRONG!
@@donovan2913 my neighbor recorded his reaction. 😂 ua-cam.com/video/u8p-bO61X-Q/v-deo.html
Kmsl he had me like wtf at 7:20. Thinking he was running up to it like a kid on their 🎉birthday. Lol
Fantastic. I am excited!
Maybe you are using a 19v solar panel, and the motor is rated for 12v. That's why it's getting hot.
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
It looks like a small pump , it's having to overcome the hydrostatic head of water so over working it
@@MrVelociraptor75 running a pump with higher voltage will result in an higher current also. Resulting in more power consumed by the pump than what it is built to.
@@MrVelociraptor75 um....no.
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....
Thank you for your explanations
