Sharing knowledge to build rich, sustainable lives.

Sharing knowledge to build rich, sustainable lives.
Appropedia is the site for collaborative solutions in sustainability, poverty reduction and international development through the use of sound principles and appropriate technology and the sharing of wisdom and project information. It is a wiki, a type of website which allows anyone to add, remove, or edit content. Registration is encouraged but not required for contributors.

Appropedia has been described as an "appropriate technology wiki," but it is much broader than that - it is a green wiki, and a wiki for all matters of international development and aid. But most importantly, Appropedia is an open site for stakeholders to come together to find, create and improve scalable and adaptable solutions.

There are four basic Hexayurt sizes which cover a variety of needs.
What is it? The Hexayurt is a refugee shelter system based on work done at the Rocky Mountain Institute. It uses an approach based on "autonomous building" to provide not just a shelter, but a comprehensive family support unit which includes drinking water purification, composting toilets, fuel-efficient stoves and solar electric lighting. Other systems can be added in a modular fashion.

Is this for real? Yes. Both the American Red Cross and the US Department of Defense have examined the Hexayurt system in detail and found that it has considerable merit and utility. I hope that we will see it in use by international agencies within two years. The best place to get started is to read the slides from the presentation Vinay Gupta gave at the Pentagon in December 2006: Pentagon Presentation (pdf) - 20 pages, not much text, and the best summary of the system we currently have online.

Projected Costs: Shelter: $200 - $500+ per single family unit depending on size, climate and use duration Infrastructure Package: around $100 per unit.

Solar Charged Lawnmower

Converting a very used gas power lawnmower into a solar charged, low emission, almost silent, lawn cutting machine.

Estuaries and coastal waters are among the most productive ecosystems on Earth.
Water is vital for all known forms of life. Covering 71% of the Earth's surface, it is found mostly in oceans and other large water bodies. 1.6% of the total mass of the Earth's water is below ground in aquifers and 0.001% is in the air as vapor, clouds, and precipitation (rain, snow and sleet).

The Earth's water moves constantly through a cycle of evaporation and transpiration (evapotranspiration), precipitation, and runoff, usually reaching the sea. Over land, evaporation and transpiration contribute to the precipitation over land - thus deforestation and other changes to land can have wide and long-lasting effects through their impact on the water cycle.

Some observers estimate that by 2025 more than half of the world population will be vulnerable to a lack of water. Appropriate water supply and water purification technologies can help.
