But still, the problem becomes, just how do I refill all that battery capacity in the middle of the night when the sun doesn't shine and when there is no wind.. The answer is always, you must have some dependable non electric mechanical source (IE ICE gen).

I'm not following your argument. Many RV'ers install 4-6 6V GC batteries, a large inverter and solar system in their rig. How is this any different? Are they not faced with the same problem?
