Perpetual batteries from Vasilescu-Karpen

Of the Al cell or the MnO2 cell d3x0r

the aluminum... was trying to do some searching on it. 


MnO2 is not something I'll be able to try; lack of incentive to purchase... the other I have the peices laying around

2Al + 3H2O = Al2O3 + 3 H2...and also 2Al + 6O(from air) = 2Al2O3...Al2O3 then dissolves slightly in bicarbonates to form aluminates.not enough incentive to get hold of pyrolusite? You don't want to be the first to violate kelvins law on youtube? It gives more of a kick than karpens original.

The MnO2 cell gives about 3-4 times more power than karpens gold/plat cell.

Change my search terms from calcion-carbonate reaction to just 'aluminum carbon battery' and found immediately instructable videos using various things... even a Aluminum air battery - http://sciencegeekgirl.com/documents/TPT_Salty_Science.pdf ... that just uses the O2 from air...
Although using graphene ink on Al foil would make a nice compact stack ... hundred squares could get 50V battery   only... 50uA... still need 400 of those to get what I need for amps


Hmm... http://en.wikipedia.org/wiki/Manganese_dioxide - first paragraph....
Manganese(IV) oxide is the inorganic compound with the formula MnO2. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules. The principal use for MnO2 is for dry-cell batteries, such as the alkaline battery and the zinc-carbon battery.[2] MnO2 is also used as a pigment and as a precursor to other manganese compounds, such as KMnO4. It is used as a reagent in organic synthesis, for example, for the oxidation of allylic alcohols.

that's not a thermal cell either :p

You forgot to google the words: 'fuel cell O2 catalyst MnO2' d3xor (-: Its a inverted-thermal cell.no need for a temperature gradient.
