Windmillprint-crop.jpg Yes it is possible to print a windmill with a 3D printer for a fraction of the cost of manufacturing one conventionaly. Learn more about open-source 3-D printing of open source appropriate technology for sustainable development.


M2-B2 Rocket Stove
Concept Art of The WaterPod (thewaterpod.org)
WaterPod Rocket Stove. The M2-B2 Rocket Stove promotes sustainability through demonstration and education while on the WaterPod in New York City. The stove is designed to provide a reliable and sustainable means of cooking by minimizing fuel use and optimizing efficiency.

The WaterPod is a project being put together by a group of artists and engineers. This project is going to take place in New York City, in which a group of artists are going to live on a barge for six months traveling down the Hudson River promoting sustainability. The WaterPod will stop off in the five boroughs of New York and allow the public to tour the barge. The WaterPod has worked with the Engineering 215 - Intro to Design class at Humboldt State University to create sustainable projects for the WaterPod. Team Mel Brooks was assigned the task of creating an efficient means of cooking that can be utilized for the duration of the project. Team Mel Brooks created a rocket stove, which will optimize biomass as a fuel source to cook for The WaterPod.

The WaterPod's only cooking appliance for the entire summer voyage. Discovery News says, "If rising ocean levels force us to figure out how to float, it might not be an entirely bad thing. Especially if the food tastes like this."

Architect Eliel Saarinen
Always design a thing by considering it in its next larger context – a chair in a room, a room in a house, a house in an environment, an environment in a city plan.

A windmill is used to power a water pump which fills a swimming pool.
Appropriate technology (AT) is technology that is designed with special consideration to the context of its use - including environmental, ethical, cultural, social, political, and economical aspects of the community it is intended for. With these goals in mind, AT proponents claim their methods require fewer resources, are easier to maintain, and have less of an impact on the environment compared to techniques from mainstream technology, which they contend is wasteful and environmentally polluting.

The term is usually used to describe simple technologies proponents consider suitable for use in developing nations or less developed rural areas of industrialized nations. This form of "appropriate technology" usually prefers labor-intensive solutions over capital-intensive ones, although labor-saving devices are also used where this does not mean high capital or maintenance cost. In practice, appropriate technology is often something described as using the simplest level of technology that can effectively achieve the intended purpose in a particular location. In industrialized nations, the term appropriate technology takes a different meaning, often referring to engineering that takes special consideration of its social and environmental ramifications.
