Amazingly, your sig may answer your own question. Given that Roger is the ultra-rich type, it may be a charity/soup-kitchen thing.

Dorothy. She joins Roger for dinner in the same ep, so I assume that she eats. That implies that she has a sort of fuel cell that extracts energy from organic material like you and I do (quite useful if you can't count on being plugged into a wall). As an android, she may well require more kilowatt-hours than you or I require calories.

As a third theory, apply the above principal to Big O.
