Engineering for Change

Interest: Water

Nearly 1 billion people don’t have access to clean water, and the consequences are fatal. Diarrhea is one of the leading killers of children under the age of five. Fortunately, the solutions needed to access clean water can be affordable and reliable. With informed design and management, drawing water, transporting and purifying it are all possible for everyone worldwide.

  • Depending of the desired temperature and the way you want to heat the mealworm. For low temperature, a solar heater (like the ones for water heaters for homes) could be enough; but if you want a higher temperature, a solar concentrator must be used.

    Heating a mealworm farm without Electricity
  • Interesting solution, some concern about vertical reinforcement being necessary for seismic and hurricane application getting lost -- shown in some drawings not others. All in all, a lot of good technical information and by highlighting the building material in the context of the application -- post...

    Good Earth Nepal Earthbag Construction
  • 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-Beam Pallet House
  • 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.

    I-Beam Pallet House
  • In general, a good concept around integrated services and financing. Still a concept, not a lot of insight for engineers or designers except from a planning perspective.

    Tiguri Green Village
  • Seems like an advertisement for the company and their product, not an honest description of what the actual solution is. Includes an integrated list of solutions (kitchen sink planning) but does not go into great detail about any of them individually.

    Tiguri Green Village
  • Nice concept, good they have have a prototype. Good example of a concept around a set of principles and requirements. Limited engineering guidance or information, but could inspire an architect/engineer team to develop something with similar goals in mind.

    Sustainable Incremental Construction Unit (Modular Housing Scheme)
  • Again, this seems more like an article about a concept or prototype that can serve to inspire designers but has limited value as a solution to be replicated. I guess there are some lessons learned from the failure, but that may be better suited to a different format or different section.

    NLÉ Makoko Floating School
  • Building collapsed due to poor maintenance in 2 years. Indicative of serious engineering challenges or failures. Interesting concept of a floating house, though I'm not sure it should be advertised as a "solution" to land issues. Perhaps lessons can be learned from the base of the structure.

    NLÉ Makoko Floating School
  • I would like to see if you are in the trial or final release stages. I distribute glasses and would love to be more accurate in eyeglass matches and want to use instrumentation that is more accurate than the methodologies we use now. Thank you.
