My wife has a vanity where she makes herself ready for the world in the morning. She likes to watch TV during the process (morning news, and all) and there is a 30 inch TV about 10 feet from where she sits.
That honker uses 70 watts of power when it's on, and believe it or not, it uses 7 watts of power when it's OFF!!
After some thought, I came up with this solution:
I took the picture with the little TV held as far away is it is while my wife watches it (it sits on her vanity).
Note the relative sizes of the two screens. The little TV is 4 inches diagonal.
It runs about two hours on 4 AA NiMH batteries, and I charge them in a solar charger.
Sometimes less is more.
