Three technologies - Chimney Solar Dryer, CoolBot, and Floating Gardens - were analyzed using a Land Use System (LUS) analysis approach. Using excel to build these models, the LUS is a relatively straight forward cost‐benefit analysis that tracks the flow of inputs and outputs over the life of a system or technology. Inputs include all the material and labor that goes into establishment and maintenance, as well as their associated costs. Outputs are either the produce harvested, such as with the floating gardens, the dried products that come out of the chimney dryer, or the stored product from the CoolBot cold room that is then sold.
