Invention Wanted: Clean Emergency Power

While waiting for the grid to come back on people need some kind of home power device that lies dormant - perhaps years - until pulled from a closet and activated to provide electricity for a few vital items. It should be safe and easy to use, is low cost and has no emissions. It would be an "electricity-in-a-box" solution that could be for one time use or be able to be refueled. Not a complete whole house power supply, but provide enough electricity to add some level of comfort to an otherwise miserable situation.
