Robert Green, an American Inventor, has developed a brand new technology which generates kinetic energy through the conversion of waste heat (as well as many other fuel sources). The Green Steam Engine is piston powered and designed for a wide assortment of practical applications. These steam engines are easy to build and can be used to power boats, electricity generators, air or water pumps, water distillers, heat pumps, air conditioners and a wide array of other small to medium sized appliances. How-To Plans and Components can be ordered directly through the Green Steam Engine website.
One of the more unique advantages of the engine is its ability to generate energy from the waste heat of engines. Essentially, waste exhaust heat from a vehicle engine can be converted into energy used to some of the vehicle’s cooling systems and pumps. The design is lightweight, small and quiet – making it perfect for many small space situations. This green engine will boost the efficiency levels of any vehicle or machine system it is installed on.
The revolutionary new patented design converts reciprocating movement into rotary movement, greatly streamlining the piston design and allowing for more versatility and project flexibility. There are limitless possibilities and advantages for clean steam power. Some of the main advantages are: less air and noise pollution, high torque at low speeds, multiple fuel capabilities, and long life with low maintenance.
About the Flexible Rod Transmission (from Green Steam).
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.
