Found this story when looking for hopeful news:
“A young entrepreneur is using 3D printers to create cheap school campuses in rural Madagascar.
It takes just $40,000 and 18 hours to build a “Thinking Hut,” as they’re called, and founder of the project Maggie Grout is aiming to get the cost even lower before handing the reins over to local professionals.”
