  • Iana Aranda says: As per Bob: reliable source of power or electrical storage and/or backup power is required. This limits the application to where this type of power is available. UV if applied appropriately can be both a safe and effective means of sterilization.

  • Iana Aranda says: As per Bob: Steam technology requires a source of water and steam – implying high power heating elements. Appropriate sources of clean, chemical free (Calcium, Iron etc.) water are necessary. Although in developed countries this is not a significant issue in developing countries...

  • Hi John, thanks for the comment. The use of smoke to repel insects is actually one of the criteria we included in the protocol. There's a section dedicated to location-specific user needs like this one (which can be expanded to include other/uncommon, but important, needs we haven't identified).

  • One of the key issues involved in the roll-out of ICS is that swathes of households in low-income countries are convinced that, although they may not like it, a smokey house environment inhibits biting insects. I've had quite a few householders tell me why smoke is a good thing, for this and other r...

  • No standards in design, requires engineering design. No windows, limited protection, unclear durability. Again, not a solution, more like an example of the use of pallets for construction in limited 1st world applications.

  • I'm not sure this is appropriate as a "solution". It is certainly a concept and an innovative use of the pallet material. There have been no updates to the pallet house humanitarian design webpage since 2010.
