Speaking of cost efficiency; i wonder what the ratio is with dry cell
alkaline batteries?
I expect that their materials cost, let alone their retail cost, far
exceeds their contained
energy.

   Well let's do some math.

I think for a AA 5W/hours would be generous. And I think $.25 would be
cheap. That's $0 kW/Hr (at least a hundred times grid), which reminds
me of something an Amish friend once said (they use batteries):
Electricity is expensive!

  Now, I wonder what an Aluminum/Air cell that ran on beer cans would cost!
