    I'm not sure you're correct about the cost, can you cite a source?
    Flexibility is often more important to withstanding a quake than strength.

    I recall an example, using different nails for construction in the South vastly increases a house's resistance to tornados and hurricanes.

    These can increase the wind resistance of a house 2x over standard nails, and don't cost all that much more.

  4. Cost is extremely important. by Anonymous Coward · · Score: 1 · on Making a Better Solar Cooker

    The Sol^R solution (pdf) looks very promising, but this passage from the executive summary bothers me:

    "In Rajasthan, [India,] the design will cost a total of $502. The cost of the unit is less important than if the unit is successful in replacing wood burning stoves. If implemented, the women of these rural villages will escape the health issues acquired from smoke inhalation while still working during the day."

    Cost is extremely important. If they can't afford to build it they'll just stick to what they have. The goal of the project is to get it under $400 for a reason.
