Slingshot, the Portable Water Purifier by Dean Kamen

One of the latest inventions by Dean Kamen is the Slingshot, a portable water purifier. What makes it unique is not the age old water distillation method but packing all the complexity of such a filtration system into something relatively portable.

By portable I mean it can easily transported, deployed, and maintained, which is something that cannot be said of traditional water distillation systems. At the size of a small fridge and the fact that it require a minimal amount of electricity make it a portable but stationary device. While another water purifier, the Lifesaver, is targeted for individuals and families, the Slingshot is more suitable as a clean water source for larger groups or small villages in need. Unfortunately it is not yet in production but if they can keep their target price of under $2000, this could even be an option for middle class families in the developed world.

It is to be seen if this can match the reversed osmosis (RO) filtration system’s ability to filter out anything larger than 0.1nm. How’s that possible you might ask, well RO filtering systems use a membrane as one of the steps in the filtration process. This “hyperfiltration” is more suitable for home usage than any other water filtering system on the market.
