Let There Be Light

Posted by admin on August 10, 2011 | View Comments
 

Millions of people around the world can’t afford electric bulbs and live in homes that lack windows, resulting in lives spent mostly in darkness. However, thanks to a program called Liter of Light, many families in the Philippines will be able to afford light in their homes by a new innovation — old soda bottles now converted to solar bulbs.

Over 10,000 homes across Manila and Laguna have the solar bulbs installed. The light source improves the standard of living in the poorest areas. You can watch a story about the invention here.

A solar bulb is created by adding water and bleach into the plastic bottle and inserting the bottle into the roof through a custom-cut hole. The sunlight goes through the bottle and the added water refracts it, creating 55-60 watts of clear light in the home. The bleach in the bottle is used to keep the water clean of algae. The device can be built and installed in less than an hour and lasts for about five years. The idea is inexpensive for the financially-disadvantaged residents. It’s a practical combination of simple technology and reuse of disposed soda bottles.

    Hi!It is great seeing these inventions and innovations. On-Innovations has come a long way. There was a interesting article on copy cats through SmartPlanet. Not all are copy cats and it also gets ideas like this in motion. I say this, as learning from the article that only 7% of product sold is from innovators product itself. In some ways it is very unbalanced as the innovator has to think of the idea (may have come from years of working on other ideas or years of determination) but it is minimal time and investment to those that are true copy cats. What we are suggesting is to a little better balance as to donating ideas to a group of young engineers. This way the innovator has less time in and at the same time stimulating our future innovators and engineers of the future. I truly think this will free up knowledge moving beyond a type of innovators grid lock and help move ideas like this feather.If it is already being done we would like to have some links to research. Tip if there are not already doing so, would be to have an area around the bottle a clean flat surface. If you determine our findings all the better. But I am an innovator work to protect our balances.Thank you RD Ford RD Fords.com

    Hi! On our fist post. I did not mean to finish the post in such a forwarding manner. We are looking for the means to a better balance to the 7% and some of our experiences have had as well.Thank you for the great post and idea. Hope you can clearly understand what I was trying to say. Not good at writing.RDRD FordRDFORDS.COM
