Starred and flagged! This is the kind of genius we need to turn
things around. Oddly, I was pondering the idea of building a
solar collector using soda bottles just 2 days ago. I also thought
about building walls with stacked 2 liter drink bottles. Why recycle
when we can build with it? Great find reticle.
The thing is you only get light when the sun is out. In a real survival situation odds are you wouldn't need light during the day, but would need it
at night instead. My idea is to get glow in the dark rings and use this light to charge them up each day.
