Storing Solar Power on my ROOF!!!

That type of plastic barrel will break down structurally inside a year.

Superb demonstration of energy storage through pilot experiment at home!❤

Why not focus on alkali lead batteries that won't die from sulfur scale

Sorry, it is not effective enough.

Fun experiment but you would need 100 barrels on your roof to match the storage power of a few Li-ion batteries.

Omg that matrix battery bit was genuinely hilarious. Well done!😂

Nice Video😀

i love invention

a fun build! For version 2, i suggest a simple way to increase the energy density, just pressurise the water above atmosphere with excess solar energy.

Solar, wind and battery are the worst investments you could ever make. Is that why they are going hydro?

You bought the wrong one, silly!

What an amazing video, thank you for sharing this with the rest of us.

And he uses metric system ❤️

Just a thought and not sure if it would help but figured id spitball it here:

If you had a clearer barrel for the water, and placed steel wool in it (or you could use black marbles), youd increase the amount of absorbed light energy inside. This should heat the water, and if it were sealed on top, it should increase the downward pressure of the water, above what gravity alone would give. This would increase your downward flow rate, and in turn increase the amount of juice you get at the end.

The tricky part is making it a closed system. Dunno if someone could engineer the increased pressure to only push downward to the ground instead of also pushing backwards against the pumped water coming upward to the tank.

Dont roast me!

man i enjoyed that video thumbs up

So smart, until the next storm winds launch it into the neighbours living room hahahahahha

Just think, you can charge your phone at the gutter now.
Cheap too.

I bought one of those pumps for my guitar humidity control system. Weird design, very inefficient, ran about 6 months. Almost any other pump would be better. Similar system ran rocks up the hill on tracks to store energy.

And your solution during the winter? Do you maintain enough motion to prevent freezing?

Did you ever think of using passive solar to put the water in the barrel on the roof?

Thats the same jump suit john wayne gacie wore

drill baby drill!

HOA president is gonna have an aneurism

Pretty cool, got to be a more efficient use of the water using some sort fo turbine vs a water wheel.

❤AWSOME❤

Updates please?

Upgrades please

It happens that the highest reservoir in oregon broke only because no one could stop the pump from filling it…. The choice of a full automatized system without even a video monitor of the water level was a terrible mistake ! Hope things got fixed with a mix of technology and common sense.

Great demonstration of the process to assist in learning concepts of mechanical and electrical engineering.

Maybe you could work additional concepts in, such as the stored water volume required to accomplish some practical task, or how inefficiency in devices like the motor in your example robs the system of energy.

Or how a similar system could be used in other ways and the energy stored could be more efficiently used in another form (I'm thinking captured rainwater pumped to the roof by a solar-charged battery operated motor, to provide evaporative cooling and reduce the electrical energy required for the HVAC system to remove heat from the home).

It is excellent! Thanks!

Great blue light at night….

Loved your video.Great job! You have a new subscriber👍

It's quite good but there are a lot of losses converting mechanical to electricity which is why batteries are preferred

Every energy conversion loses a %. Solar water heating and insulate the container saves energy.

Wouldn’t the mains pressure be enough to send the water up without the pump ?

I have a real fun watching this video. One like is mine...❤️

How long does the the salt water battery last on full charge with out solar panel

Did you ever consider adding wind turbines . As you said show me a small amount of time the solar is available, however wind turbines will work even if there's a slight breeze.. anybody not provide you with all the power you need but it is a good one to help make up power

14k joule, makes only 3.89Wh of energy.
As you mentioned in video, you need to scale up to power a house.
If you scale it up for 1000 times, then you will have only 3.89kWh of energy.

It means a reservoir, instead of barrels.
Then there will be other problems to start. Maintaining, cleaning and water loss to sun.

Btw, if you connect the flow valve to a governor, maybe there will be an autocontrol of power.

Still a good explanation. Thanks.

in a closed cycle use windmill to pump water to high tank.

Look at all the water towers. Piped to the height then massive volume. Its about 3feet of water to get a pound of pressure.

This video made me extremely angry because he could have just bought a $6 solar powered light thats solar panel foot print is a few inches,charging an 18650 in a package weighing a few ounces if he wanted a light. But hes just standing there smiling like hes some kind of genius. His mom gave him a solar panel because she knows...and feels sorry for him.

In India we all hv rooftop water storage. Either pumped up with electricity or government water supply (which can go up to 2rd floor, for free)

I become aware of how dumb I am when I see someone create, design and build something like this.

An Archimedes screw would be more efficient to use. Great video

This is genuinely cool. It functions with style.

Why not go simple and do a ram pump take snow power and pumps uphill or to the top of your roof

How have you managed to “see you on the next video” when i have my cameras covered? ;)

Congratulations! You just built your own personal pumped hydro battery😂
