I am so proud of Sierra. She is almost finished with her big 5th grade science project. She has done a great job.
We went with an idea that we hoped would promote some kind of humanitarian effort. Sun cookers are used all over sub-Saharan Africa. They are advantageous because they require no fuel, can be done outside and without the danger of smoke inhalation, and they keep nutrients in the food being prepared. I think that we simplified because of time, and possibly our position globally, but we went with just water purification.
She took several days to conduct a series of tests to see which configuration worked the best. The wheelbarrow seemed to hold in the most heat, and within about 4 hours, she was able to obtain and sustain a temperature that would sanitize water to safe levels. Pretty cool.
I wish that we could take this simple project and find a way to get it where it's needed. There are certainly better ways, more complex ways, to provide clean water. But the fact that we made it in our driveway is just inspiring.
Please google sun cookers if you interested in this topic, and while you do, pray for the millions of people around the world who do not have access to safe drinking water. We are all thinking about Haiti right now, as we should. But before the quake, and in so many more places around the world, there is incredible need. Let your heart be moved to act, to give, to pray.
