I have been "shadowing" Vinay Gupta via twitter for a while now. He is the creator of the hexayurt, a durable structure that a family can live in comfortably for about $100. The Hexayurt Project's "Six Ways to Die Model" - too hot, too cold, hunger, thirst, illness and injury, is used to guide thought and action toward ending poverty with open hardware. The Hexayurt project has been gettin some attention since the earthquake in Haiti, and hopefully they will see Vinay's creations appear after some rigorous testing.
Be sure to check out the hexayurt project site at http://hexayurt.com/
