As many of US based folks know, walking into Wal-Mart allows one meet the many daily needs of life in one centralized location.

Similarly to Wal-Mart, I wonder, could a Public Works Substation allow an Iraqi to gain access to MicroFinance, gain access to knowledge about a small-cost effective windturbine/led light/car battery system, gain access to knowledge about a small-cost effective ceramic water filtration system, gain access to knowledge about generator repair, gain access to a doctor/physician assistant/nurse/pharmacist? Would a working wind turbine at each of these substations provide a visible advertisement of hope to supported neighborhood?

Along those lines I offer some websites that might be of interest.

But to provide rapid improvement for the poor we need a system that draws in innovators and businesses in a far better way than we do today.
