All children should watch this brilliant, altruistic man. Thank you for sharing with the world. You make a difference!
completely agree! 💯
The perfect description for The Dread Mad Scientist Robert.
Leak detector with 20+ years lifespan.
one of these with a buzzer installed under showers or washing machines.
You'd know earlier than when it shows through the ceiling.
fascinating demonstration.
I love this idea of yours!
I once lived in an old house with problematic septic system. The full tank would back up into the bathtub (not so bad) but also leak around the toilet drain wax ring onto the floor (so bad). Of course the previous owners put carpet! So I bought a water detector alarm and put it behind the toilet. It would sound like a smoke alarm if the carpet got wet. It served us well until, ironically, the battery died.
@@DistracticusPrime carpet in a bathroom… what were they thinking?
@@oddjobbob8742Our high school has a carpeted cafeteria. Nice '70s burnt orange loaded with formaldehyde. The whole school has the stuff.
@@misterhat5823 they tore out part of my home town’s 1925 era high school to do plumbing and electrical upgrades. The guy who did the demolition thought he had a great idea. He would very carefully dismantle the bathrooms to save the marble walls and floors to resell. He was convinced it was going to be a money maker. He low-balled his bid to ensure he got the job. Then found out that 70+ years of piss on the floors from boys splattering and even the smell of stool in the girls bathroom had so penetrated the marble it was worthless for re-sale.
Now I'm thinking of lining up the bottom of my kayak and make it a perpetually self-propelled vessel...
Hi flasha😂 that sounds like a plan. I'd love to give that a go. I'm all about self sustainability, sorry self reliant. We all need to stick together and help each other ✌️
"Beef it up a bit" or as Tim the Tool Man Taylor would say... "More Power"! Oh Oh Oh.
That was usually moments before disaster. 😂
Al: "Tim, I don't think that's a wise course of action."
Tim: "Nonsense! Listen to that baby purr!"
*comical explosion*
I wish we had applied science or engineering projects like this in high school, or even college/uni.
WOW! - Yet again! Simplicity, inert safety, salt & vinegar electrics, - appears so easy & cost effective, that Everyone CAN DO it. Well done. Thank you for sharing it.
Rob, you make it look so easy and understandable. We are blessed to have you as a mentor.
I am just glad it helped
@@ThinkingandTinkering would exposure to high humidity cause any issues with the longevity of this? Or would it require actual liquid to soak across between anode and cathode? Thanks in advance for the reply, I’m a huge fan of all of your videos, they’re fantastic and you make the concepts easy to follow and learn / understand. Cheers!
Most excellent. Your best work always involves a battery.
You can also add a hygroscopic material such as Hydrogel or equivalent, to constantly draw moisture from the air that drip condensate into a anhydrous acetic acid or citric acid powder, placed sandwich between other layered cells. If done right, You've now got yourself a self continuous charged battery cell.
I'm very proud of the work you do and thank you for taking the time to bring it to us.
I freaking love your channel, Robert.
Been watching your stuff across several accounts for over 7 years
and me - he's wonderful
Even The Dread Mad Scientist Robert’s original CZcamss are worth watching, over and over.
Brilliant Robert. I wish I knew the voltage that that battery cell makes.
Cheers. Chuck in Florida.
It’s about 1.5 v. I found a chart with various electrode configurations.
I had a cheap digital watch that was bought in the pound shop back in the 80's that ran on water, you soak it in some water and away it worked for a few days to a week . . it's like they vanished into thin air, I can't even find any record of them!
Are you saying it was a disposable digital watch or a rechargeable digital watch? Either way for a pound in the 80s is really hard to imagine
@@you-know-who. It was rechargeable,using the water, I can still remember it, the body was a green ish translucent plastic with holes in the side that had a wicking material for the liquid, the face of the watch was the calculater type. Well the shop was the pound shop style, cheap stuff, but the watch could have been a fiver or a tenner, but no more than that.
@@you-know-who. I had the thing for years until we did a house move and it dissapeared.
Was looking for this comment.Yes, I remember these! Do a search for "water powered watch 1980s"
@iangraham6730 that sounds exactly like the sort of thing that would just disappear from existence. I not one bit surprised
Great idea. It was way cool to hear the motor ramping up as the oasis soaked up the electrolyte. Cheers
Haha, was thinking the same.
of course you do a little Bagdad-battery just love it Rob! /Mikael
Or just keep the materials around. When you have an emergency. You can MacGuyver that shat to impress people.
I think it is better to just have a professional power bank.
But knowledge is useful if blackout happens when you are visiting your friends
@@szogun1987generally speaking it’d be superior for sure, but the batteries in the battery bank will degrade over time, even when not used. This specifically won’t really do that if well sealed from moisture for years, perhaps even decades.
I have questions. So once the electrolyte dries, can the cell be reactivated by adding more? How long does an activated cell run? If one wanted to stack multiple cells in a single container, what material would be a good divider?
Definitely worth experimenting with, even 100mA from this cell would be good, 250mA is impressive..
for sure mate
A brief search of the Web only gets you rechargeable LED torches, so I think I'll hold onto my pedal-powered generator.
What a bright idea! Note: Pun not intended, but definitely accepted!
lol - cheers mate
I think this video will have as many questions attached to the comments as there are thanks... A follow up is needed Here Bob,,, Maybe make a few and scale em up, vinegar percents and the like... Great video as usual
I only wish I could give MULTIPLE thumbs up for this great video! Thank you!
Those tiny rectangular soy sauce bottles with the top removed work really well for this too. You can just about get a stack of 2 cells in one if you are careful.
I made one with a piece of copper sheet and a piece of magnesium sheet and used just salt water. The copper could be from old water pipes if needed , and as for the magnesium - an old mag alloy wheel from the scrappers would do - but cut it up fist.
Oh cmon rob you cant tease us with that, great little battery but how big does it need to be provide say 12 volts with about a 10 amp capacity, i can. Scale up from there.
Interesting way to recycle old batteries. (Zinc harvesting)
I love your channel. I learn so much! thank you!
I love such simplicity. Thanks.
Fabulous demonstration- I love the simplicity and how easy it is to make this. I can imagine how useful this can be in places that have unreliable power supplies- scaled up it could run a peltier cell fridge, for example.
Wow! Hearing the little motor ramping up with every drop was awesome! Is the zinc reaction reversible?
Creme of Tartar may also work for the acid. Most people have it in their kitchen.
I make these with the kids.
What I would like is something like this but rechargeable..
They make powdered vinegar too. You could mix the vinegar powder and the salt and water, soak the oasis, let it dry.
also, being these are only I would guess 2-3 volt cells, you could stack and parallel them for larger voltages straight out of the build, parallel for amperage, series for voltage. I would not try them to even be a regular car battery, but you could get to 6 and non volt batteries pretty easy.
Is it just me or has the video quality improved? Rob’s looking 20 years younger now;)
Thx u thx u so much for ur videos n info. Please don't stop making them keep on u have saved the day 🙏
I feel like Jesse from breaking bad looking at this like "ahhhhh wiiireee!"
Id love to see a recreation of the Egyptian solar panels made from obsidian and copper 1/2 of it got to be soaked in phosphorus the other half not maybeupgrade it by putting it in a plastic or glass container
It was discovered in the 19th century that steel ships tended not to rust when pieces of Zinc were fitted to sides, above the water line.
Above?
Hey Rob, would you please consider building a diy wind generator for us to self build. It would be interesting to see what you come up with. cheers.
I saw something similar in an old magazine from the sixties. I think it was either Popular Mechanics or Popular Electronics.
so brilliant. love it.
WOW !!! Thank you Sir
In an emergency would urine work? Is there a battery design that actually uses urine? A long storage life dry urine battery would be a great application for an emergency locator beacon.
Smelly option. But urea, uric acid, tend to break down quick to ammonia and other substances. Would a base battery have different electrolytes? Maybe works similarly. Ammonia and salt, say. Urine, fresh, for emergencies only?
Very interesting and useful. I presume the voltage is 1.5 volts.
I was thinking about the multiple ways power can be generated today .When our electricity went off and none of the power companies were helping. I have a son with Duchenne muscular dystrophy who relies on multiple machines throughout the day Most only have a 2 hour backup. I definitely have to build something .Just not sure what right now .
Petal powered generator for sure
Urine could do as an electrolyte instead f the vinegar solution too I reckon.
FANTASTIC!!!
That's pretty cool, I wonder how likely the foam is to absorb moisture from the air in a humid environment? If I were making it I'd vacuum seal them after assembly just in case, the peel open and fill with water.
What voltage do they produce? Must be around 1.5v by the looks. I like it, I might build some for the hell of it. Roll them up into cylinders to make the AA size will compress them well too, though I wonder how much that will effect its ability to absorb water.
very cool. how many volts did you get out of it? it would be cool to see a few of these in series/parallel to see how much it could power stuff, place in the garden, when it rains voila;.....excellent.
this is brilliant!
Thanks people like You, Independently minded.
If you did video I missed it - Electricity from air/Antenna to ground, with 4Diode 4 Capacitor circuit, between Antenna and ground. Idea has made its appearance while back.
Keep Tinkering and sharing the knowledge
Brilliant
This channel and neebs is like the only thing on CZcams
And the electrolyte makes tasty potato chips
Outstanding!
Great video! Thank you....
Glad you liked it!
Fantastic!
Wow !! Amazing.....great idea..
No wonder I feel recharged after a nice chippy... Must be all that salt n vinegar....
BRILLIANT ! [ pun intended ]
Any way of "recharging" this once used?
I got a ton of pop cans. Thinking about power bank. Layer after layer. Dry cell. Prussian blue.
I had 6 dc volts die hard. But used salt and it erodes. So back to drawing board. Thx 4 the education. Cheer's
Love your videos! Can you tell me if these batteries are RE-usable? Thanks
I am amazed. 🙂
I purchased water activated AA batteries from Ebay about 10-15 years ago
Powdered Tanic acid instead of vinegar will work as well. I wonder if powdered tea leaves would work as well ?
Is there an acid you can prelaod the Oasis using IPA as a carrier so it evaporates more quickly?
That is pretty amazing. Is there any way of guesstimating how much power would one get with a bathtub of vinegar and electrodes of corresponding size?
A interesting read and researcher names to learn more. Article by TechXplore: Ammonia-powered engines: A path to cleaner and more efficient transportation
here's one i did on that subject mate czcams.com/video/4fdc_eW9OZk/video.html
@@ThinkingandTinkering Thank You Robert, Thank you for the link. I had watched that video. Became een more interested. I did research on line . AI....LOL....thought I should learn more and kept feeding me links on the topic to read up on. That researcher name came up. So I researched Him, and thought what an interesting chap to read about while researching more. Thank you for the mental prompts sent often to learn more. My ears are getting longer as I have been running down many STEM Rabbit Holes in support of my habbit of life long learning. Your videos bring MUCH Clarity ! Thank you for these gifts that keep coming. If you ever visit Washington D.C., here in the States, let me know, we should walk the Smithsonian
Museums of your most interest, and then have Dinner. Enjoy the Day !
What you suggest I would do with some zinc acetate solution? Have some lying around cause I needed to clean zinc off of some metal pieces that needed to be welded together and used as a heater. Some zinc I got from them pieces, but not all rest I had to grind/sand off. Anyways the thing is complete now and in use as a heater/wood stove.
Awesome!
Any thoughts on 3d printing a container for it and making it a multi cell battery?
That is amazing!! ❤
thank you mate
Was that 200mA hr or was that 200mA max current? What voltage was that output?
You so have to show us how to make a 12v one of these.
i just had an idea. you know looms and spinsters wheels have those footpedals to keep them running. I wonder if you could make use of such a foot powered device to power a HEPA filter for doing sterile labwork in front of. I see you say they use the carbon filter in aircons or whatever, but squirrel cage blowers are pricey and tke a lot of electricity, ad can blow out / fuse. Would be SO cool to be able to have a foot powerd laminar flow desk where sterile air is blowing over the workspace in the lab to do sterile mushroom tissue culture where the footpedal through some mechanism creates constant wind pressure through the HEPA filter for sterile airflow on the desk, i.e. laminar flow hood for sterile tissue culture in a laboratory. Also I wonder if it's possible to make a High Efficiency Particular Air filter at home with reticulated carbon foam or something? The problem is the micrometer size at which or through which particles are let through, to prevent contams landing on the er, shroom myceium? The idea is to obtain a pure tissue culture to propagate the dears. You could have two pedals so you are like basically exercising while powering your laminar flow desk, instead of wasting a ton of electricity and also having to replac a squirrel cage blower, as that HEPA filter requires a strong current of air to force a consistent flow of sterile air through the high efficiency particulate air filter, so would love to know..
How big could you scale this up? Say use the whole block of foam?
Robert, what would you calc the m.a. hours to be for your example?
Very cool stuff! My like made it an even 700 likes! 🎉
This a salt water battery used at sea for warning and rescue purposes ect
Or you could make a light like I did, that will provide light for 12 months, or flash for 10 years, on a single dry cell.
What was the voltage created?
My emergency light has heat too, pretty cool it's called a candle.
It's pretty cool when you get more heat than expected, in the form of a house fire lol
have you tried scaling it up just to see what you could get out of it?
I wonder if a water battery is rechargeable after "run down" but still wet. ?
There are a lot of generators on your channel but which ones are actually fit for home usage, output wise?
And if you don't have water (to waste) urine will do just fine or better.
What happens when it dries out? Can you re-add the solution or do you need a new setup each time? Thanks for helping!
Eventually the zinc will be consumed and it won't work any longer.
My last 3 attempts to obtain activated carbon felt was not too successful.
Would distilled water make a difference?
I wonder how big it would have to be to run an entertainment center
Can you put a few in series to achieve 12v
How big would I need to make one to run my air conditioner during hurricane season? 😅
Cool
What is its capacity the one you made?
Interesting. Can we make this into a refillable battery instead of a rechargeable battery then? Wait, isn't that how a car battery normally works?
Is that 5% vinegar or something else?
Did anyone try this? What Is the cell voltage?
Change from zinc to aluminum, now you have an aluminum air battery, right?
