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.

Hexayurt Project

The Hexayurt is a refugee shelter system that 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.

Wangari Maathai in 2006
As long as there is no trust and confidence that there will be justice and fairness in resource distribution, political positioning will remain more important than service.

Aleiha's parabolic solar cooker
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.
