Overview

In Brief
This challenge seeks to provide a low-cost shelter and utilities solution for use in emergency relief and housing development for the world's poorest communities. Science for Humanity is looking for a sustainable, longer-term solution which can be manufactured with local labour and materials.

Geographical Area
Various. A solution to this challenge has the potential to help in disaster relief or for housing of the poorest across the developing world.

Haiti: The Hexayurt has particular relevance for earthquake-hit Haiti and is being further developed for the climactic conditions of Haiti’s hurricane season. Science for Humanity is facilitating the Hexayurt’s examination by structural engineers for its capacity to withstand high winds and strong rain. It is also raising funds to assist with the testing of the Hexayurt in Haiti and the project management of its eventual deployment through local NGOs.

Relvant Scientific Participation
Science for Humanity currently has engineers collaborating on this challenge. There are a number of aspects to this challenge which require volunteers from other areas of expertise (e.g. material scientists). Join the Hexayurt Group to get involved or to follow the progress of this challenge, particularly in Haiti.

What is the nature of the problem?
- Tents are most often used as emergency shelter in relief situations and these are usually too cold in cold areas, too hot in hot areas and deteriorate within a few months.
- Emergency shelters have to be brought into emergency areas, which requires time and the high costs of transportation (e.g. air freighting).
- Tents cannot be used for long-term shelter and do not assist the re-housing of refugees after an emergency.

What is the nature of the opportunity?
- Hexayurts provide a low-cost and sustainable solution for disaster relief.
- Hexayurts are more like houses than tents and can come with an infrastructure package.
- They can be manufactured locally using semi-skilled labour and materials such as cardboard, plastic and plywood. Therefore, they can be easily mobilised.
- Hexayurts can last up to three years rather than the average three months of a tent.
- They can be relocated with the refugees to provide longer-term housing.

Challenge Requirements
1. The structural and thermal computer modeling of Hexayurts - We need to be able to take a material, measure its physical properties under load (e.g. snow) and come up with accurate predictions about its performance under a range of field conditions.

2. Materials research on low cost industrial panel manufacture - We need a specification for a simple panel material that can be mass manufactured cheaply in the developing world, not necessarily on site, but using local manufacturing capacity. One promising approach is a very thin, lightweight aluminium sandwich panel derived from the approaches taken with cardboard honeycombs rather than from aircraft panels.

3. An effective timer valve for pasteurization processes. We need a valve and sensor package which will open automatically when the water being pasteurized has been at 65c for 8 hours. Although clever approaches using melting wax or color changing chemical reactions may be possible, it may be more effective to mass manufacture a low cost electronic device.

Insulation

Regarding insulation, I feel that it may be better for the unit to be insulated as a secondary process – i.e. supplied in naked form with cladding for insulation applied subsequently.   Obviously it…

Using plastic ties to hold the panels together is a compelling alternative to the use of tape. Simply slice a very small slit through each of two adjoining panels - a pair of slits on top and a pair…
