Natural gas generators are probably the best "battery back up"
has anyone here used any of the new natural gas powered whole-house generators yet? Seems like a brillant concept in case power goes out to your area. Remember the big power outage an New York and the northwest that was caused by one tree branch in Ohio or thereabouts?
If you put your entire house on natural gas powered generator for when your main electricity is cut, you will look pretty smart if there is a natural disaster.
