hi,
i reckon a solar panel would be great! so it charges a redstone ciruit during the day and turns off at night. this would be good for a huge door in a wall, at night it locks shut, but at the time all the mobs start burning it will open. or solar/glowstone lights. at night it uses glowstone to light the room, in the day it uses the natural light. it could even be used for a cactus/ reed farm, harvests in the night, but lets it grow in the day. i can't do the crafting squares but it would be crafted like this:

The way it would work is this:
The thermometer blocks becomes charged if...
A - If it is in sunlight or in the maximum light level from any source, unless water is touching it.
B - It touches lava, unless water is touching it.
C - It touches fire, unless water is touching it.
So it could be used as a day/night detector and as a liquid detector and as a fire detector.
