The Geysers in Northern California.
Geothermal power is generated from the high temperatures that can be found in various parts of the earth's crust such as volcanoes, hot springs, and geysers. The water that surrounds and fills the gaps between the rocks in the crust is raised in temperature by these natural processes. This hot water is then pumped to the surface and its steam is captured and used to create electrical power through a turbine system.

There are three common types of geothermal power: dry steam, flash steam, and binary cycle. Dry steam is rare and uses the steam directly from the earth, flash steam pumps the hot water that naturally occurs in the earth to the surface and utilizes its steam, and binary cycle uses a secondary fluid and its vapor to power a generator.

Dry stream geothermal plants use natural steam directly from the Earth. Once the steam pocket is tapped, the steam is channeled directly into a turbine which converts the thermal energy into electrical power. (more types follow)

The Vitruvian Man is a world-renowned drawing created by Leonardo da Vinci circa 1487.
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.
