Emergency Water Desalination
I'm on a team of junior level engineering students who, as a design project have been tasked with creating an emergency water desalinator. It is our understanding that very few smaller vessels carry any sort of device like this - largely because of cost. We have a conceptual design, however, none of us have any real experience sailing. From those willing, we would greatly appreciate some input.
Here's the basics:
1. Remove salt through evaporation instead of expensive RO filters or through FO filters that require a sugar-like solution.
2. Total weight 15-25lbs
3. APPROX Dimensions of: 2.5ft*1ft*1ft
4.Production of 1-2 gallons/day should be very easy
5.Total cost to produce >30USD
6.We are attempting to make this work only requiring hand-power($$), but may require electrical input (similar to that of car battery) to achieve 1-2 gal/day. (Evaporating water is very energy intensive)
Are there any thoughts given that much? Anything you would or would not like to see in this type of device? Do you realistically seeing something like this being included in your emergency supplies? How many consecutive days would you want to be able to count on this device providing water?
Any thoughts that you have would be very much appreciated and seriously considered.
