the water battery

video

kind of impresive, without water it can last longer then any other battery
and when needed a few drops of water activates it.
kind of kool

Nice, that's certainly very innovative. I wonder how much power it can generate per say, millilitre of water. I imagine you'd have to replace the battery itself as well eventually, as I'm sure the reaction that produces the current slowly uses up the carbon in the battery.

No doubt there is some process going on which uses something up, but if it can replace the heavy metals in current batteries, and will be cheaper could be excellent......

I'm going digging to find out some more from a chemical reaction point of view.

Very interesting.

I was just watching something that said those emergency lights on life jackets in airplanes actually use water as an electrolyte, which I didn't know. So possibly this invention isn't new, just an innovation of the idea.

But a very good one, I'll say. 1/10th the cost, unlimited life, and all you need is a bit of water. It's things like these we need for the future.

Fantastic idea...

I hope this idea for the new battery gets rallied behind as battery waste and disposal is
a huge problem in landfills everywhere..

Great post!

the vid did not work for me , [ i curse codec incompatability ] , but it looks IMHO like a quite modest improvement to current " dry charge " battery technology

i used "dry charge " lead acid accumulators , car batteries to the uniatiated over 15 years ago - and they had a IIRC shelf life of 10 years + with no mainainance [ a wet car battery has a shelf life of < 12 months sans maintainence ] - just pour in the 6 acid vials [ one / cell ] and they were good to go - you were supposed to let them stand and charge them before use - but no one did - it probally shortened cell life etc - but we did not care

ok the ones i used contained lots of toxic and corrosive chemicals - but i loved them .

these new ones are just a green upgrade IMHO

and latly i believe that " water battery" is deceptive hype - they are dry charge chemical batteries - the water just provides an ionic conductor to complete the internal circuit

final point - i would be impressed if they could be " drained and dried " - to extend service life once you fill a conventional dry charge battery - there is little turning back - you then have to maintain it

if these new ones could be filled , partialy used , then drained to return them to " long term storage " that would be ultra cool

A green update can't be a bad thing though, right ape?

appologies , i came off totally wrong there , yes - i think " green upgrades " are cool as heck

i would love to see hi capacity mainanenfe free batteries with a huge shelf life that do not need a hazchem data sheet .

i was just calling it as a saw it

Would there be away to use the carbon emissions we are desperately trying to reduce as the source of materials for these batteries?

A brilliant idea.

Being driven home from a friends house almost ten years ago, their father told me it would be wise to get a career in developing new ways to store energy... how right he was.
