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!
