clean and safe? Dr. Sarah Haigh, a researcher into the properties of nanomaterials at Manchester University, is currently pursuing this goal with a $100,000 grant from the Bill and Melinda Gates Foundation. With the help of nanomaterials and bacteria, Haigh believes that hydrogen can be easily extracted from not only the water, but human waste itself, which could then be processed into clean water. Should the system work effectively, Haigh stands to receive an additional $1,000,000 grant to further her research and develop inexpensive purification systems for use in nations without modern infrastructure. And you thought nothing worthwhile would come from purchasing Microsoft Office.
