Selfmade 3 Volts can battery with big power..

[hartiberlin]

Have a look at this video...

Normally you get maximum about 1 to 1.5 Volts out of such
a unit, how does he get 3 Volts and this lot of power ?
Is this a fake ?
Did he hide 2 normal batteries later in the can ??

What do you think ?

its hard to hide something the way he present it, its maybe possible its just a question of right ingredient proportion no?

[hartiberlin]

Hmm,
maybe he made a cut in the video,
poured the fluid out of the can and did
hide 2 AA battery cells there and put them in series,
so he gets 3 Volts  ?

Stefan , you can  put 2 different metal wires in to an citrone or an apple.

you becomes also  0,7 to 1,5 volts  ( see the  physic lessons  from scolol , to chose the best metalls)
3 volt in AA sizes or also botton cells . are avaiable  as "lithium-cells"

possible  it was " wired  before in the can , and connected "trickly"
by epxerimentator.

3 volt is not "power" , this is only an voltage.

Its totally possible to get 3 volts from an galvanic cell such as this.
All it requires is the right reduction potentials in your metals.

Example:
Li+ + e = Li (E= -3.040V)
Just a half cell of lithium can produce 3 volts

His cell is composed of a copper anode and a steel(?) cathode.
The Sn/Zn can may act as a catalyst of some sort...
Definitely worth checking out if you're interested in galvanic cells.
