How The 2-Liter Bottle Can Change The World (And It Doesn’t Involve Mentos)

Wednesday, August 3, 2011

When the good folks at the YouTube taught us that a delightful volcanic eruption occurs when Diet Coke and Mentos are combined, we thought the wonders of the world-renowned soda had reached it’s peak. But in a recent video posted on the blog Notions Capital, we see that the Coke bottle (well I suppose any 2-liter clear plastic bottle would do) has a much more commendable potential than exploding into a fountain of high fructose corn syrup.

Introducing the zero-energy, zero-cost, solar-powered light bulb.

But how does it work, you ask?

Find a big plastic soda bottle, preferably from the trash to make it really eco-friendly. Wash it out and then fill with water. Add a few capfuls of bleach to prevent the growth of algae. Screw the cap on tight.

Snip a hole in the congregated tin roof of your house, lean-to or shack, and shove the bottle halfway through. Seal with caulk or some other type of water-tight substance.

Wait for the sun to shine through and, bam!, you have the equivalent of a 55-watt light bulb, sans electricity. For people living in the poorest regions of the world without access to, or money for electric bulbs, the bottle light has the potential to significantly improve the quality of life, as Notions Capital describes it, for “billions of poor people in sun-swept favelas, shantytowns, and bidonvilles and scattered rural dwellings around the globe.”

Will the use of this “light bulb” end poverty and restore equality for all? I’m guessing not. But it is a glowing example of how we as convenience-minded humans can negotiate creative innovation in sustainable energy.

Or, at the very least, we can pimp out our dream treehouses.
