For the last 2 months, we've been rocking our brains out how to lower our electric bills. For some reason, it doubled over summer! Anyway, for DIY day, how about an experiment?
I recently heard about 1 Liter of Light in the office. It's an ingenious idea crafted at Massachusetts Institute of Technology(MIT) in 1996, then adopted in the Philippines by MyShelter Foundation early this year. The use of the Solar Bottle Tubes in dark rooms during the day promises enormous savings in electric bills. Ok, this is promising... a little extreme for some, but may be a good thought as an alternative for daylight roofs in the storage garage or dirty kitchen, or perhaps a project for the children when introducing science & environment.
All you need for the device is a used plastic bottle (preferably 1.5liter soda bottle with cap); purified water; chlorine; salt & rubber sealant. Fill the bottle with water, 3 bottle caps of chlorine & a pinch of salt, then seal with rubber sealant. The water refracts the light, while the chlorine & salt slow down evaporation & prevent growth of molds. The solution is expected to last up to 2 years before you need to change it. Not bad!
Ohh, I can't wait to try this with our children in church. Let there be light!
