By the time we get to that point, I suspect lithium batteries will be superseded for most applications. That said, several battery technologies that were supposed to have died a death are still very much alive and kicking. Lead-acid are still mainstream, after all. NiCd aren't going away anytime soon.

Don't shoot me, I'm only the piano player. I DON'T work for or on behalf of EON.Next, but am willing to try and help if I can. Not on mains gas, mobile network or mains drainage. House heated almost entirely by baby dragons.

Back to basics. How about the Potato Battery. 😂😂😂😂

That is a very nice potato battery. With exactly those metal foils I'd expect you to instantly double output by using lemons instead. With lemons for acid and six cells in series, you should be able to get an LED to light.

Back to the topic which called me to this thread,
https://www.youtube.com/watch?v=5B6icvUBNzE
Parts of the presentation look not quite right but it does mention some interesting trials.
The University of Queensland design looks like a perfect swap-in fit for a CR3032 'coin cell' so rather than discourage their efforts I'll say that they seem to have a rechargable little battery which could be tested.
The MIT group also propose something interesting. If theirs contains sulphur then there are sure to be ways to get that to burn. I did not see enough metallic Aluminium in the explanations of either type, so they can't have high capacity.
For claims like these, I say always test.

Now, from the wizzo227 preposterous things which might blow up department, pick a fresh lemon and insert a foil of pure nickel into a slot carefully cut into the top left. Insert a slab of pure potassium into the top right. That should get a higher voltage than the potato experiment, until it blows up.

There is already a rechargeable variant of the CR2032. The LIR2032. Land Rover fit them to their fobs. Contactless charging when the fob is inserted into the slot in the dash. Most Land Rover owners keep the spare fob in the drawer and just use one fob until the battery fails, and then go to use the spare only to find it has self discharged to the point it won't work. Two new fobs and reprogramming...£400! Swap the fobs over every two weeks to keep them both active...ten years lifespan easily, and even then the battery replacements are only a couple of quid and five seconds with the soldering iron as their cells are tagged.

If you sat each of those tatties in a saucer of slightly salty water, you can double the capacity and run-time. 20μAh instead of 10μAh. It makes all the difference. Obviously, they can't share the same saucer.

Alternatively, if you chit the tatties and then plant them, you can grow even more batteries next season. What's not to like about renewable energy? And when the batteries are dead, disposal is just a matter of home composting. None of the hazards of disposing and recycling lithium chemistry batteries. Win-win all round, I say👍🤣

Which is precisely why I think potatoes are the way forward 😂. Also way better for the planet as less air/food miles. Renewable and recyclable. Now I wonder how many tatties would be required to run that EV? 🤣😂🙃

Fear not, my friend. I have already addressed that question.

Back in the day, steam locomotives used to pull a tender with supplies of coal for a journey.

Behold, the eco-friendly power solution for your Tesla....🤣

But rather like the 'Duracell Vs Energiser' debate...Maris Piper or King Edward?!!

I'll place an order on Amazon straight away. Oh but I haven't got an EV. Still I can distill ethanol from the spuds and fill my banger up with that. There you are it just goes to show how versatile this vegetable is.

Definitely Maris Piper.

@meldrewreborn @wizzo227 @WizzyWigg @retrotecchie, I absolutely enjoy how you all can speak up about a specific topic and also have fun with it!

You guys know your batteries don't you! I am not an engineer and I have never been too good at chemistry but I do love learning new things so apart from Potatoes, Kinds and Queens I think this was an absolute success!

What do you think ? 😁
