Complete Freakin Genius! A 2 Liter bottle produces the light of a 50 watt lightbulb for free!

I LOVE LOW TECH SOLUTIONS PROBLEMS!   This is amazing.  Someone in Brazil had the idea to fill a 2 liter bottle of water and install in on your roof for FREE lighting!   This is far better than cutting a hole in the ceiling because the water and the shape of the bottle captures the light and disperses it like a light bulb!  The water also acts as an insulator!   Each one apparently gives out the equivalent light as a 50 watt light bulb.
