Awesome 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Very clear explanation. I will try this some time.
Here is an idea. Not sure if it would work at all but here goes. I have tried a few things that produce voltage but negligible current this could be another one of those.
If you have two granular (sand like) materials with different electronegativity (aluminum vs lead) as well as a buffer sand and you had them mixed in some electrolyte solution (just wet) or maybe dry. Imagine there are collector plates on the top and bottom of the mix. Is there any chance you could generate voltage with usable current as the particles moved up or down (because of liquefaction) based on their density and difference in electronegativity? Just a thought. If it worked it would only produce when in a state of liquefaction and there would be no real consumption of material.
Best start may be to have a layer of buffer sand covering each of the collectors. As the liquifaction begins the heavy particles would sink and the lighter ones with float making contact with their respective collectors.
I could not find this idea explored anywhere so likely not viable. ChatGPT did not say it had no chance of working.
Thank you very much for the useful videos. Is it possible to show the preparation of sodium batteries?
bon travail, c'est intéressant pour le principe du flow... mais:
ça reste un fuel cell qui, comme les batteries primaires ne se recharge pas: du gâchis de matière et de la pollution à mon avis😪
les accumulateurs, supercapacitors, redox flow, ... ont de l’intérêt car rechargeable.
methanol /ethanol hydrogène fuel cell pourquoi pas, c'est accessible et renouvelable... pas l'aluminium ou les terres rares...
en tout cas ce que vous faites est genial😀😉, ça aide beaucoup de monde sur l'autonomie énergétique
merci
Great iteration man
I was thinking of something similar where you threw aluminium cans in although the paint/coatings/continuity on the cans would cause problems. Difficult but nice if you ever get it to work.
In other words a "trash" battery. Yes the coating on cans will make a problem
Very nice concept that enables the extended use of a primary cell and, instead of a traditional primary cell, keeps re-using the basic battery infrastructure and only swaps out the consummables (aluminum anode and electrolyte). I don't know the full energy and financial accounting of this architecture but seems like scaling up would benefit those equations....although I do still think while it "looks" inexpensive to just use something so seemingly cheap as household aluminum foil, the larger equation of the energy and financial cost to produce aluminum would still keep this as an energy source more expensive than the burning of hydrocarbons....however, pure financial expense is not always one's objective and I can see a lot of useful applications for this.
Yes, you are right. Really nice by this cell is that you can use zinc or better iron. I mean, with this cell you can use all what you can find,.... which is good in some emergency situation.
Burma👍
Me párese un buena idea,, me gustaría ver cuantos volt. Produce y cuantos Amperios o miliamperios
1.4V and 300 to 500 mA depending how hard you press the aluminium into the cell.
i would like to see a all-liquid "refillable" fuel cell, for example use the reaction between bleach and hydrogen peroxide, separated by a proton exchange membrane. (similar to a hydrogen fuel cell) I'd try it myself but i dont have to tools or equipment to try it.
You already have something similar,... it is called a Direct methanol fuel cell, which methanol is used as the fuel.
@@cayrex does that make co2 emissions though? I'm looking for a fuel cell, or battery (other than hydrogen) that doesnt create greenhouse emissions. something super cheap, can make at home, that i can replace my EVs battery pack.
@@jr-pl9kj Yes it produces CO2 and water. Yes that is a dream device,... no greenhouse emissions, super cheap and so powerfull and energy dense that can power a EV.
Do you have characterization values available? Discharge curve, Coulomb efficiency, energy efficiency, energy density, power density, etc?
Would it not be easier to have an open type of cell and physically lift the Al electrode from the electrolyte when not in use?
It depends. I mean, yes you can lift the aluminium electrode out from the cell. In that case you will need to lift the aluminium from each cell if you have many cells or it is made a battery housing that will lift all the aluminium electrodes at once from multiple cells. You also need to replace the electrolyte from time to time also.
I've removed aluminum and put it in vinegar after use. Rinse thoroughly before putting it back in the cell of course.
looks like putting a coin in the machine
Hahhaa,... It has similarities, yes
yep lol, also try zinc nitrate as zinc plating rechargeable battery, same as zinc sulfate plating in water solution electrolyte. might be a be touchy to heat, so the sulfate battery is better in that regard@@cayrex
