These requirements must be met so that the design is achievable for both a small clinic and because the teams budget is very little. The Frame- This outer wooden covering can really be made out of any type of lumber accessible. Drexel's Innovation Design Studio will supply all the lumber necessary for the Solar Sterilizer.
