This goal of this project is to build a low cost Stirling engine that can generate electricity (around 1KW of power output). We have completed a prototype engine for proof of concept and to test out materials and linkages. Now we want to scale the project so that engine can be used for real work. This engine will have around 1KW of power. What does that mean ? Well the average US household uses about 8,900KWH of electricity per year - that comes down to 24 KWH per day and so our goal is to have a minimum engine output of 1KW so that it can produce close to the average home use of electrical power per day (24 hours of 1 KW output give you 24KWH). We have a cost target of less then $100, in cost, for this engine, with the majority of parts made from commonly found commodity components. At the completion of the project we'll provide open source plans for construction of the engine along with kits that allow purchase of the components or completed engine.
