I've searched high and low to find a Zamboni High voltage battery to purchase, but can't find a source. So, I am offering to pay someone to fabricate at least one, and preferably two, Zamboni Batteries for me (also called a DuLuc Dry Pile). I am willing to pay generously for a job well done. Attached is a file about Zamboni HV batteries for general information. If you are interested in this, contact me via email for discussion. CM

Seems a bit pointless to me. Try a PVC pipe full of button cells!

Find someone like oatley electronics who sells crappy LR44s in bulk for cents each.

Personally, I'd ask first what you want to do with it...

...then I'd ask if the fact that this is your second post on the forum means the only reason you joined the forum was to parasite off the members to get your HV battery built

hehehe - I might be mistaken, but we're worth more than that, mate =)

Hey, he said 'pay generously' which is one of my favorite two word phrases. It doesn't sound that hard either. How big of a pile do you need (voltage wise) and what are you going to use it for?

When I used to work for phase engineering (midi and amplifier repair place) it was standard practise to take all the 3V lithiums (maintains volatile memory etc) and replace them as a matter of principle...

A few weeks later I had about 150V worth... I held them together in series with tape, wrote "TOWER OF POWER" on the side, and left it lying around in convenient places such as on the kettle... in the fridge... on my desk. It was severely popular!

Would a couple of PVC pipes full of watch cells not do the trick for you? seems a very easy way to do it without silvered paper etc etc... :-/

What do you plan to do with it? You are not going to have more than a few ma/hrs in it, so unless you are just using it for electrostatic experiments it won't last at all (and probably won't be able to put out more than a few ma). I almost wonder if it would last very long just sitting with the amount of constant corona...

I suppose the most important question is what voltage do you need. I would recommend a 9v battery/button cell which can be hard pretty cheaply. batteries and butter has some 20cent 9v's... Even it you need 10kv that is a mere $200

That would also give a lot more storage/current capacity...

Yes, I am interested to learning the end application as well. Are you just trying to get the output voltage or are you doing this for historical purposes?

I've been a long time member having made many posts in the past and secured the services of more than one very bright persons from this site for past projects, but for some reason when the site upgraded, it no longer recognized my pass, so I had to rejoin, thus the reason for the low post count. (I wouldn't mind if the moderator changed my post count to 40 or so, which is easily how many posts I've made in the past).

The short answer for why I want a Zamboni is: I own two patents and just filed for my third, part of the 3rd application includes a circuit I developed that transforms HV to LV more efficiently than using a transformer. Eventho a Zamboni is extremely low amperage, I'd love to see how my conversion circuit performs when using a Zamboni as the HV source. Now then, here is the MAIN reason a Zamboni is attractive to me... Zamboni HV batteries are documented to operate for up to 50 years, and in atleast one case, claimed to currently be operating a electrostatic motor for over 100 years (see attached article). The battery eventually does run down as the electrolyte breaks down, so it's not the perverbial perpetual energy source, but it is a long-term energy source of HV/low amperage. A goggle search on Zamboni Battery reveals other articles stating the longevity known to be associated with these style HV batteries. Delicate fabrication such as is required to construct a Zamboni battery isn't my favorite activity, so I'm seeking to compensate someone to construct one or two Zambonis for me, approximately 3 feet long each, should provide ample voltage to operate my circuit.

To be honest, anytime i see the term "perpetual machine" mixed within a supposedly scientific article, i become very wary.

Isnt a zamboni that big machine that drives across the ice at halftime?

Im not sure if you have thought about it but you could probably use a Van De Graff generator to power your circuit if you want HV, low aperage. It is a far easier task to build a small VDG then a "zamboni" battery of any size.

EVR: The article only mentioned perpetual motion in so far as to say that the Zamboni battery was _not_ a perpetual motion machine. As far as I'm concerned, CM has money ("Generous" amounts of it too) and he wants a straightforward but tedious job done. Is anyone going to take up his offer?

As a technical aside: the amp-hour capacity of a battery is presumably determined by the chemical energies of the electrode materials, and won't vary much no matter how those materials are assembled. So it's probably wrong to believe that the dry pile batteri is somehow more efficient. A three foot long stack of D cells could probably power a tiny motor for 100 years too, if it weren't for the fact that the guts of the D cells corrode and fail by themselves after about 10 years. The dry pile battery must just have a very long shelf life due to its very low activity. If I understand the principle right, the electrolyte is just the moisture naturally present in the air.
