Power a boat, a generator, air pump, water pump, heating blower, water distiller, heat pump, air conditioner, model airplanes, boats and trains or a variety of appliances with any fuel that will heat water including solar and geothermal. Waste heat from engines or manufacturing processes may also be used to generate steam to power this engine. Because it is so lightweight and compact, it could be used in vehicles to run pumps on waste heat; saving power and fuel. This powerful, quiet engine is a breakthrough in alternative energy use. Because of a revolutionary new patented means of converting reciprocating movement into rotary movement, the "Green Steam Engine™"  has dramatically simplified the piston engine.

(note: pump in front of flywheel to recycle condensed exhaust steam)

Typically, the exhaust steam is condensed and pumped back into the boiler to increase efficiency. A small pump on the engines pump the condensed water into the boiler in a closed loop system.

Steam engines provide advantages such as: less pollution, quiet running, high torque at low speeds, no transmission requirements, runs on a choice of fuels, has long life with low maintenance. 

Adding to this list of special advantages, the "Green Steam Engine™" offers these unique features:  

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.   

This engine may be made in a variety of configurations and sizes. For example, one can change piston size and stroke length in a matter of a couple of minutes. One cylinder may be substituted for an air pump cylinder to provide air or water pumping. It can have one or a plurality of cylinders without increasing the number of bearings.  Modern materials and methods have been applied to this steam engine to achieve new results and to bring steam power up to date.

Two Cylinder Direct Drive Generator

The engine shown below is especially designed to operate with solar collectors or a small boiler including household pressure cookers. It produces sufficient speed to eliminate belt or gear drives and operates on 10 to 50 psi of steam pressure.  

  The engine fits nicely into a tube for compact designs.

Water distiller operated by small steam engine

 This device produces up to 24 gallons of distilled water a day, charges batteries, and makes all the hot water you can use employing an ordinary household pressure cooker on a low simmering fire. This model steam engine operates the system on 4 to 20 psi of steam pressure.
