Cultura Colectiva has reported that Xóchitl Guadalupe Cruz, an 8-year-old girl from Mexico (Chiapas), has been awarded UNAM’s Institute of Nuclear Sciences for creating a device, totally solar-powered, which can heat water.
This device uses recycled and recyclable materials. Xóchitl’s invention might seem a tad unnecessary for 1st World Countries, but in her community, the only source of hot water is cutting up logs that would not only release fumes into the environment but also lead to deforestation . . .
