This guy reckons he charges a mobile phone with it.

Btw I can think of at least half a doz ways I could fake this but they seem deadly serious about charging the phone. One guy claims he had 27 volts with a 50ft antenna. I built the circuit but only got mv when hooked up to the telly aerial on the roof. Min d you I think I had the wrong diodes.

G'Day all,
@One:  I can assure you a "dry cell" is galvanic. It is just not as wet as a "wet cell".

@ Jimboot
If you are interested in galvanic reactions your should learn about the electromotive series. The farther apart the two metals are in the series the higher the voltage will be between them in a battery. Here is a link to a not very good list. You can find better lists and discussions in basic college chemistry books and maybe on the web if you spend some time looking.

A battery needs a solution with free ion to work. The fewer the ions in the water the poorer the battery will work (lower current). It is hard to get pure water. Tap water has many impurities in it. Distilled water is mostly pure but there are grades of distilled water. Laboratory grade is much purer than what you get in a grocery store. But however pure the water is, it will probably not be pure once you put it into a container because most things have surface impurities even after coming out of a dishwasher.

Your last video was good at showing your setup.

LOL, thats a good one ----- this reminds me of the person who said I will listen with an open mind but won't believe a word I hear.
Galvanic action is a word to describe a process which is electrostatic in nature as all processes are electrostatic in nature. If you believe matter is composed of opposite charges as physics states-- Proton/Electron then all matter must be electrostatic in nature thus all reactions must be as well because nature cannot utilize something that was never present in the first place.

QuoteThe entire problem with ALL theories of today, is the theory about Magnetic Force! All theories of today are WRONG! They don't even understand what it is.  I DO, it is PARTICLES.
Metal does not make magnetic force, it only holds it and circulates it!  You have to find out what "it" is.  Ed Leedskalnin claims it is might actually be electrons running against another particle (protons?), but also says even the electron theory is incorrect and it is something else!
Electricity is magnetism running in streams (dc). Metal magnets are AC.  Very hard to explain in current day theory.

Thankfully somebody here can see past the illusion of effects and examine cause, you are light years ahead of most of the people here.

G'day all,

@allcanadian:  I'm not sure what you're point is here. What is incorrect about a dry cell being galvanic ?
