I think the competition guidelines are around manufacturing cost, not retail cost:

> The cost per liter of water extraction will also be calculated based on a pro forma Bill of Materials and estimated NRE and tooling costs. A more detailed description of this calculation is provided in the Rules and Regulations. The Affordability Index must be less than $0.02 (two cents). No prize will be awarded to a Team that does not meet that criterion.
