In the past, cheap and small-scale desalination devices have seen much success. For instance, desalination cones, or solar stills, have long been used in wilderness survival kits or to purify brackish water for small-scale consumption.More specifically, Ryan Erickson, a fellow high school student from Los Alamos, NM, recently designed and built a desalination device with very similar specifications to our design brief.

His machine both desalinated and sterilized the water, as ours hopes to do, and it is just as compact and affordable as we would like ours to be. Therefore, these past successes show that we should be able to accomplish our goal efficiently. A single-family desalination device is well within the realm of possibility for three high-school engineers.
