Questions & Concerns

Arborloo

• If the facility is too nice the Haitians will use it for storage, but if it's bad then they won't use it at all. How do we make a balance?

Pasteurizer

• Will the surface heat up to the point of burning someone, given that the environment has to be very hot (~50C)?
