This is a plugin designed for the now-defunct server Mine21, and gives the recently-introduced Daylight Sensors a new usage: power Furnaces! No more coal mining or burning wood! Its usage it's very simple: just place a Daylight Sensor on top of a Furnace!

As every solar panel, they require a strong light source, so they don't work in the Nether or the End, and they must be directly under the sky, with no opaque block (glass is OK) above it. You can still use Coal and any other kind of fuel in them as you will do with standard furnaces. Those fuels will be used when there's not enough light, for example at night.
Please note that adding support for a new version doesn't mean dropping support for an older one. Thus version 1.3.1, which adds support for Minecraft 1.6.2, will also work in 1.6.1, 1.5.2, 1.5.1 and 1.5.0 (it won't work in 1.4.7 or older because light detectors didn't exist!)
