lol no @mark E.im telling you that it sucks in heat from a single thermal reservoir against resistance in order to attain electrochemical entropy,the only way which is to squeeze,squash,compress,saturate gas from one electrode onto the other.spontaneously.otherwise why do we measure a nernst potential in e.g. a wikipedia oxygen concentration cell in direct proportion to oxygen gas exposure differences between electrodes? Where does that potential for work come from?thin air? I dont think so.the first law of thermodynamics forbids work from nothing and i agree with it.the 2nd law forbids work from something and i dont always agree with it.

Profitis, so that's no on recharging without external energy?  And it is also no on going away from equilibrium without external energy?

[profitis]

no @mark E.thats no on you and me requiring to put in energy.not no on the universe requiring to donate energy, from a single thermal reservoir.

no @mark E.thats no on you and me requiring to put in energy.not no on the universe requiring to donate energy, from a single thermal reservoir.

Profitis, the original pair of questions are each a yes or no.  If you want to add explanatory detail, that's always good.

The first question was:

Profitis are you telling me that without consumption of external energy one of these cells will recharge itself? 

I interpret that you are saying that the answer to this is no.  I interpret that you say it is no because of the First Law of Energy. 

The second question was:

Are you telling me that it is the luck of the draw that one of these cells discharges towards equilibrium versus moves towards 100% concentration in one cell half and 0% concentration in the other?

I haven't found anything in your responses that appears to address this second question.  If I missed a response somewhere, then I apologize and ask that you clarify with a yes or no.  Of course I welcome any expansion you may wish to offer beyond the yes or no.

 @mark E. 1)no work is needed to recharge it.an expanding gas will suck in heat from the universe as it cools.the battery sucks in heat while the expanding gas(compressed during discharge half of cycle)  recharges it. 2) no its not luck.its a vey precise switching between 2 directions of entropy going on in the battery: discharge= electrochemical entropy dominates.recharge=gaseous expansion/diffusion entropy dominates.2 seperate entropy needs in one system,only one need dominating at a time,depending wether the battery is switched on or off and depending on how much resistance is between its terminals in the external circuitry that we need to work(grey areas inbetween totaly on and totaly off,ohms)does this answer give more clarity for your 2 questions @mark E?
