Plans
http://www.greensteamengine.com/products.htm
Complete plans for constructing an engine. Includes:
- drawings and dimensions of all the parts
- Diagrams for assembly
- Complete parts list
- Help-line for questions and trouble shooting
A person familiar with the operation of a drill press, band saw and threading tools can make this engine. A small metal lathe is optional. Most of the parts are modified, off the shelf, items.
Applications
http://www.greensteamengine.com/flex%20rod%20applications.htm
"Many new ideas for products will emerge from the "Flexible Rod Transmission" . Inquiries for manufacturing license agreements are welcome."
- Air and Water Pumps - Multiple cylinders with overlapping phases supply a smooth flow of air with reduced load.
- Traffic Barrier Strip - Rotary output activated by a pull cable in same axis as output shaft.
- POP Displays - Multiple activation of separate parts with individual timing and amplitude.
- Bicycle Derailleur - Horizontal movement without rotation by a pull cable.
- Water Propulsion Device - Rotary output from reciprocal activation at a distance.
- Model Airplane, Boat or Train Engine -
Patent
(US patent # 6647813 (http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=/netahtml/search-bool.html&r=1&f=G&l=50&co1=AND&d=ptxt&s1=6647813&OS=6647813&RS=6647813)) 2003, Green
Key Features
Quoting from http://www.greensteamengine.com/
- The properties of the patented crank mechanism (called a "flexible rod transmission") invented by Robert Green, provides this engine with the advantage of eliminating the typical crankshaft and cam that requires lubrication and precision machining. It also provides the unique configuration whereby the cylinders are aligned in the same direction as the main shaft. The result is a compact, lightweight and slim engine that is extremely simple to construct and assemble.
- The pistons and valves operate off a short piece of flexible shaft. Because the flexible shaft is fixed and cannot rotate, the piston rods and valve push rod are held in position while being reciprocated. The cylinders float, attached to a swivel ball fitting at their base. Much of the structure and weight of a typical steam engine has been eliminated.
- The unique feature of the "Flex Rod Transmission" is that it produces an intermittent movement whereby the valve movement is stopped in its open and closed position during the power and exhaust strokes. This gives prolonged, fully opened valve timing. In compliment, the pistons are held stationary while the valve moves between phases. The output shaft continues rotation while the pistons stand still. The result is that the efficiency is increased dramatically. The overall friction of the engine is reduced due to the small number of light weight moving parts, and the use of ball bearings throughout. The flex rod is nearly frictionless as the flexing is like a spring in which the energy required to flex it is returned in equal amounts.
Advantages
General Steam Engine Advantages
Steam engines provide advantages such as: less pollution, quiet running, high torque at low speeds, no transmission requirements, runs on a choice of fuels, long life with low maintenance.
Green Steam Engine Advangates
Quoting from http://www.greensteamengine.com/
Adding to this list of special advantages, the "Green Steam Engine" offers these unique features:
- Runs on very low steam pressure and low volume (freewheels at 2 psi),
- Costs little to build,
- Nearly zero lubrication requirements,
- Can be assembled or disassembled in minutes,
- Extremely lightweight,
- Few moving parts,
- Boiler requirements are minimal,
- Can run in any position like an electric motor.
- Very small profile for economy of space.
- May be variably configured for desired power vs speed requirements.
- Utilizes modern materials and methods previously not applied to steam power.
- Highly versatile and elegantly simple.
Criteria Score

(0 = least; 10 = best)
I. Renewable energy source= 10, device scoring = 10 ,
II. Environmental Impact =10
III. Cost (cents / kw-h) =7 (no fossil fuels required, but can be optional)
IV. Credibility of Evidence =8
V. Stability / Reliability =7+
VI. Implementation =10
VII. Safety/Danger to Persons =9
VIII. Politics of science =10
IX. Open-Source conducive =7
