Actually, that's not quite the case here, but I thought it made for an eye-grabbing headline.

How To Turn a 2-liter Bottle Of Water Into a 50-Watt Lightbulb
I found this over at wisebread.com -- very cool.
It's not often that I'm taken aback by the simplicity and power of an invention, but this one does it for me. It's cheap, anyone can make one and it literally changes lives. Welcome to the water-bottle lightbulb.
The inventor's name is Alfredo Moser, and his idea is spreading like wildfire through his neighborhood in Brazil. Like all really great ideas, it was born out of necessity. During a 2002 energy blackout in Brazil, Alfredo's workshop was plunged into darkness. And so, using a simple 2-liter bottle of water, two capfulls of bleach and an old 35 mm film canister, he created this lightbulb.
By cutting holes in his workshop roof, the new water-bottle lightbulbs could shine the sun's rays directly into his dark workplace, bathing it in light that enabled him to work again. And friends and neighbors have been using his invention to light their homes without having to pay for electricity. Obviously, this isn't a solution for your average home in America, but it could easily work in your garden shed or another type of workshop.
See how it works at YouTube.
No primitives at this bonfire yet.

Ok? So what happens when you get monsoon rains that they get in Brazil? And last time I bought light bulbs they were about 1.50 for four of them! Are light bulbs really that big of an expense? :lmao:
