Super Cheap Nanotech "Tea Bag" Cleans Water Instantly (Video) : TreeHugger: "Could a simple 'tea bag' of carbon and antimacrobial fibers that costs just pennies be the solution for quickly filtered drinking water on the go? Scientists from Stellenbosch University in South Africa hope they've found the solution to drinking water problems in rural African communities. Lacking water sanitation services, the communities can turn to a simple water bottle that uses cheap, removable sachets to clean their drinking water. And comparing the clean water solution to tea bags isn't far off -- they're using the same material that go into producing bags of rooibos tea."
