SDU Posting from Guatemala and Nicaragua
Over the next month or so we will be posting from our secret headquarters in Guatemala, with a slight detour to Nicaragua for about a week.
Reality Check – We are working on two development projects. One is a treadle pump that is easy to assemble and efficient to use. The design is intended for rural farmers, many can only grow one crop per year during the rainy season. With the pump they can grow a greater variety of crops and more crops per year. The pump design is by the BLUELab students at the University of Michigan.
The second project is a solar refrigerator. It uses charcoal and ethanol. The system is so simple I don’t know why it isn’t used in more places.
We will be publishing both designs over at www.apptechdesign.org over the next month.
SDU will be updated frequently from the road. We are taking a couple of travel computers and hope to find some WiFi spots along the way.
Photos from our adventures will be posted on our Flickr account.
Cheers,
