As long as I don't mess with the laws of mass and energy, my battery can be=
 the same size, just more efficient.  No?

Perhaps to others my questions are silly, but it is helping.  Thanks!  (But=
 I'm not ashamed.  I often ask strange questions when trying to learn somet=
hing new.)

The short answer to your question is :YES.
BUT it would be a very large battery.

The typical annual energy consumption for my home is about 9,000kWattHours =
or 9 ,000,000WattHours At 9 volts that is 1,000,000AmpereHours A typical ca=
r starter battery is 50 AmpereHours So your hypothetical battery would need=
 to be 20,000 times larger than the car battery Since a car battery occupie=
s about 0.5 cu foot you are looking at a battery of 10,000 cu feet.
or a 22 foot cube.   Hope you have a big yard :-)
