Appropriate Infrastructure Development Group

Here is what the AIDG web site describes what it is they do:
The Appropriate Infrastructure Development Group (AIDG) works to provide rural villages in developing countries with affordable and environmentally sound technologies...Through a combination of business incubation, education, training, and outreach, the AIDG helps individuals and communities gain access to technology that will improve their lives. Our model provides a novel approach to sustainable development by empowering people with the physical tools and practical knowledge to solve infrastructure problems in their own communities.

I'm really impressed + what's important is they are designing technologies appropriate to local needs and conditions + I think the concept of grassroots design (s) does make sense.
