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 according to the posts I read on https://www.watersoftenergurus.com/kenmore-water-softener/,  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.

TED Talks – Make filthy water drinkable by Michael Pritchard


Too much of the world lacks access to clean drinking water. Engineer Michael Pritchard did something about it — inventing the portable Lifesaver filter, which can make the most revolting water drinkable in seconds. It can filter up to 6000 liters of water completely free of all viruses, bacteria, and heavy metals.

This makes it very well suited for saving lives in poor countries and providing clean water for disaster stricken areas. Plus it is a nice portable way to get some fresh clean water when camping, hiking, or for outdoor sports like long distance running and biking.

“For $20 billion everyone can have access to safe drinking water. So the 3.5 billion people that suffer every year… and the 2 million kids that die every year will live.” -Michael Pritchard

At the same time it is no match to 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 (as well as some revitalizers do – check alivewater.com/store/catalog). This “hyperfiltration” is more suitable for home usage for two reasons: (1) It produces the cleanest water (2) the convenience of not having to pump manually to get water clean. Companies such as Lenser options various quality of filters for different filtration devices that can help filter multiple types of elements.
