IDSA announced the winners of IDEA 2011 at the end of June. I’m finally getting around to perusing the gallery. There are a lot of great designs, of course, but one in particular immediately caught my eye due to it’s similarity in concept to one of my student’s projects.
Pure is a water bottle designed for adventure tourists and world travelers that filters and sterilizes water from any source within two minutes. Pure contains two chambers. Dirty water is scooped up from a lake, stream or dirty puddle by the outer chamber. The inner chamber is then plunged through it, filtering water particles as small as four microns. Once filtered, the water is sterilized by a wind-up ultraviolet bulb.
Having used finicky water pumps on backpacking trips, I love this design. My student had a similar idea, but unfortunately didn’t take the time to research the science and technology behind water filtration. The end result was a concept and form study with nothing real to back it up. Timothy Whitehead of Loughborough University, on the other hand, has a working prototype that is proven to filter out 99.9% of impurities. It was also the recipient of a 2010 James Dyson Award.
