Monolithic dome office
Monolithic domes are constructed following a method that requires a tough, inflatable Airform, steel-reinforced concrete and a polyurethane foam insulation. Each of these ingredients is used in a technologically specific way. This technology was developed by the Monolithic Dome Institute (MDI). The domes can be designed to fit any architectural need: homes, cabins, churches, schools, gymnasiums, arenas and stadiums, bulk storages, landlord dwellings and various other privately or publicly owned facilities. The dome, when finished, is earthquake, tornado and hurricane resistant (FEMA rates them as "near-absolute protection" from F5 tornadoes and Category 5 Hurricanes). MDI has also developed the technology to build so-called "EcoShells". These are simple structures to provide for the basic needs of a family. They are designed specifically to answer the needs of shelterless people worldwide. They are strong structures that can withstand natural disasters, fire, termites and rot. In underdeveloped areas with hot climates, EcoShells make affordable, low maintenance, sturdy housing. In industrialized nations, EcoShells make superior workshops, garages, storage sheds, etc. Read more...

All exceptional abilities initially arise as defenses.

Those who have health have hope, and those who have hope have everything.
Arabian Proverb

An individuals health greatly influences their ability to support themselves, provide for their family, and contribute to the community. Because of this, access to care and the health of a community is central to any development effort.

Unfortunately, health care is poorly distributed around the world. Southern hemisphere countries are much more likely to suffer from lack of access to care. One aspect of this disparity is the health technology gap between developed and developing nations. While developed countries continue to invest in high technology equipment, developing countries often lack the most basic health care tools. Appropriate Medical Technologies (AMT's) can help communities, governments and development agencies create simple, low-cost, and culturally appropriate responses to health care problems.

The use of appropriate technologies is less common in healthcare than other fields such as construction or agriculture. However, there is significant crossover between the public health field and the water and sanitation fields, areas that are more familiar with appropriate technologies. Appropriate technology is often used to develop mobility and rehabilitation equipment as well as tests used to diagnose diseases.
