In 5 days I'm going to Uganda. We 're going to set up a small hospital in rural village on a mountain about 4500km alt. The major problem about infrastructure there is that there is no power supply. Because of this there is no refrigerator to store medicines, the microscope I just bought will work only until it's battery is discharged, and the people there are totally disconnected from the rest of the world. And because there are many places like this in these countries, it came to me that if I could install a solar panel and a rectifier/battery charger/inverter in the so called hospital (actually it's more like a small warehouse right now) and an other one in the so called school something good might come out.
And because founding is the major issue in these things, I was thinking I (we) could design something on CC licence that could cost 1/10th of market prices and anyone that wants to help in places like this could build with drawing already published.
The solution might be something like [cheap solar cells - 12V car batteries - custom circuit]. Who knows? Maybe later we figure out how to make solar cells by ourselves and don't even have to buy these.
So, what do you think?
