I don't know if non-hobby related items are allowed, but I saw this and wanted to share. It is an Indiegogo campaign to fund providing a portable device to produce chlorine from salt and water, to be used in purifying drinking water to communities without access to safe sources. Seems worthy of my support. https://www.indiegogo.com/projects/one-device-endless-impact-water#/
