Why overunity MUST be difficult or even impossible to replicate.

Woooow reaaallly @mark E so calculate for us the exact potential energy storage in precisely one gram molar nickel hydroxide(Ni(OH)2) coupled to one gram molar MnO2 under air in 1M NaOH then.I got him by the balls now @lanca (-:

Profitis: you would first have to show that for that volume and weight The available energy from those reagents is euqal to or greater than any other known potential energy store of the same mass and volume, which you of course cannot. 

[profitis]

Heeeeheeee @lanca look at mark E squirm now lol! @Mark E did you pass your high-school electrochemistry grades or not.please calculate the energy density of one gram nickel hydroxide coupled to one gram MnO2 in alkali under air at 25degree c..I'm not going to let you get away with this this time.please consult your standard potential table

If you think that configuration is anything close to the maximum energy density by weight or volume that one can pack in a black box, then you have another thing coming.

@mark E all we want from you is the calculated power density from one gram mole Nickel hydroxide coupled to one gram mole MnO2 in alkali under air.can you do this for us please.

All I want is a house in Malibu, and I don't even have to pretend I am a we to want that.  If you can establish that chemistry is the mist energy dense known to man then I will sit down and work out the value you seek.
