Windmillprint-crop.jpg As part of a 3-D printing class, graduate students will be designing printable open-source appropriate technology for sustainable development. If you want a technology designed to be 3-D printed, post your ideas here. Chosen designs will be made and open-sourced for the global community. Deadline Nov. 13, 2014


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.

In physics, energy is an indirectly observed quantity. It is often understood as the ability a physical system has to do work on other physical systems. Since work is defined as a force acting through a distance (a length of space), energy is always equivalent to the ability to exert pulls or pushes against the basic forces of nature, along a path of a certain length.

Sustainable energy is the provision of energy that meets the needs of the present without compromising the ability of future generations to meet their needs. Sustainable energy sources are most often regarded as including all renewable energy sources, such as hydroelectricity, solar energy and power, wind power, wave power, geothermal energy and power, biomass fuel and energy, and tidal power. It usually also includes technologies that improve energy efficiency.

While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas, where energy is often crucial in human development. As of 2011, small solar photovoltaic (PV) systems provide electricity to a few million households, and micro-hydro configured into mini-grids serves many more. Over 44 million households use biogas made in household-scale digesters for lighting and/or cooking, and more than 166 million households rely on a new generation of more-efficient biomass cookstoves.
