The HelpH2O project was a very good project but a little confusing. It had many great aspects and tackled the issue of not having clean water readily available to everyone in need. The need is first shown, by giving statistics of all the people that do not have access to clean water and the statistics of those that have a water related disease and even examples of a few diseases, such as the Guinea worm.
Their method of getting clean water is to use things called methanogens which are anaerobic. These organisms would eat the bacteria that are what causes all the diseases and give off methane as a waste product. So they have tanks in which the dirty water starts in and the clean water is then transferred into the clean tank. The Methane that is produced is also put into a separate container in which the methane can be transported for use elsewhere. Although, the methane is dangerous, I think this is a good clean way to solve the issue of water scarcity.
