Steam Engine Construction Set

Introduction

Steam engines are a robust energy source which played a main role in the industrial devolution, and may now be a viable candidate as an engine of the post-industrial revolution. Tinytech in India manufactures steam engines for various industrial swadeshi applications, primarily in India. We believe that steam engines, coupled to flash steam generators, are also relevant as an appropriate technology choice in the 'developed' world. As such, we are proposing an open source steam engine project, to deliver an appropriate technology, modern steam engine:

• Open design
• Scalable in power from 5 to 100 horsepower
• May utilize electronic valving for mechanical simplification
• May be coupled direcly to linear dynamo - feasibility study required

In particular, Factor e Farm is interested in utilizing these steam engines in the LifeTrac line of tractors, cars, and solar turbine electrical generators.

Design

Engine

• Cylinder - cylinder is made from cast iron.
  • To cast this cylinder from scrap iron, use a (how many?) pound melt, and use a simple melting furnace such as (here?)

Boiler

A simple boiler implementation involves a Babington_Burner heating the inside of a 6 inch metal pipe of 1/8" wall thickness. A 100 foot long coil of 1/2 inch steel tubing is placed inside this coil, and an electronically-controlled Valve delivery system.
