Having access to the cheap electricity most of us don’t take it as a big deal. However, this is not the same for many people around the world, especially in third countries where the poor people live in tiny homes that are most of the time made from cardboard or other weak materials. But, for the people that live in the San Vicente Village in San Pedro, in the Philippines the problem is even worse - Their houses are always filled with darkness. And, it’s not because the sun does not shine in the Philippines, but because of the thin plywood homes are packed in so tightly together that there is no room for windows so that means the sun light cant come threw. To make everything worse, the people were trying to separate the rooms; the people hang curtains inside, making the homes even more dark. The only light that could go through their homes are single bulbs powered by electric generators. Since they have to be on 24 hours a day, it is very expensive and it costs $6USD a month – That is a fortune, in a country where the average amount of money you get paid monthly is between $100-$150USD. But, thanks to a local philanthropist the people living there can finally seeing the day light! The Isang Litrong Liwanag (A liter of light) project, was inspired by MIT engineer Amy Smith's bottle bulb that she invented for Haiti. It involves constructing a small hole in the iron roof of the houses and fitting in a bulb - Except, this is not your ordinary light bulb - But a recycled 1.5 liter plastic bottle filled with water and a little chlorine bleach. The bottle bulb reflects the sun's rays, creating 'light' that is as bright as a 55-watts bulb! The water does not get moldy, and each bulb that costs only $1USD to install, can last up to 5 years, before it needs to be replaced.
I choose this article because it stud out for me. It was different, and also I choose it because it is taking stuff that can save our planet if we recycle it, but since most of the people in the world don't, we can use it for other things like helping other poor people that need help. From this article I have learned that not only money can help the poor, but also our inventions. I knew that the information is true as soon as I saw a video that shows them actually in action, the link to this video is at the bottom. Once I read this article I was happy that some people are actually doing something about the loss of plastic and helping other poor people.
This brings a lot of scientific knowledge to us because I leaned that when you mix water with little chlorine bleach, that can create light on the sun. After reading this article I have absolutely no questions about it.
