Market Applications

The broad market applicability of S-RAM technology is virtually unprecedented. S-RAM technology can be substituted for existing mechanisms (such as crankshafts, bent axes, swash plates, and wobble plates) used in various types and sizes of engines, pumps, compressors, expanders and related equipment. S-RAM enabled devices can include internal and external combustion engines, hydraulic motors and pumps, continuously variable transmissions, air and refrigeration compressors, wind and wave powered generators, hydrokinetic systems, and many others. Following are major market segments where S-RAM technology has significant application potential.

Power Generation

S-RAM technology can be used as an ideal power source for various types and sizes of generators, ranging from innovative linear generators to large-scale packaged systems capable of operating on the electric power grid. S-RAM offers a number of desirable features including a small number of moving parts, compact size, light weight, low emissions, high efficiency, low heat buildup, quiet operation, low vibration, and an ability to utilize a wide range of fuels.

Agricultural and Construction Equipment

Designers believe a hybrid hydraulic S-RAM engine can eliminate the need for a separate hydraulic pump normally used to operate construction and agricultural equipment. This integral hybrid approach has significant advantages over conventional engine-and-pump combination designs, including the ability to reduce size and weight while enabling new operating characteristics such as dynamic variable speed drive.

Compressed Air

Air compressor manufacturers also represent an attractive potential market for S-RAM technology with opportunities ranging from 5 through 300 horsepower designs and larger. The S-RAM has the ability to mechanically vary capacity while maintaining a fixed head clearance, which is not possible with other drive mechanisms.

Hybrid Hydraulic Engines

The S-RAM mechanism is so fundamentally simple that it can be used to design simple, robust, lightweight internal combustion engines as well as reversible hydraulic pump/motors.

Hydraulic Equipment

The Hydraulics industry has evolved into an extremely promising market because the S-RAM mechanism solves aprofound problem: low efficiency at low rpm. Equipment using hydrostatic transmissions, including farm equipment, lawn & garden equipment, and construction equipment, all represent potential licensees.

Marine

The marine engine industry is entering a new era characterized by ever-more-stringent emissions controls, lower noise targets, and calls for better fuel consumption. Just a few short years ago these considerations had no real impact on the marine engine market. Today, however, they are prime motivators and can be applied to virtually all marine engines, from very small to very large displacement models. S-RAM technology provides the capability to develop a comprehensive family of marine propulsion systems that deliver superior acceleration, speed and durability while occupying less space and consuming less fuel. Potential sizes range from 25 to several hundred horsepower.

Oil Industry

Oil field production involves pumping large quantities of difficult fluids such as slurries and recovery chemicals used in injection, transfer and process applications. S-RAM technology offers significant opportunities for efficiency improvements in this market segment.

Hydrokinetic

S-RAM technology enables the hydrokinetic designer to “think outside the box.” By placing a S-RAM variable stroke pump behind a rotor in a moving stream, and by coupling the pump’s output to an on-shore hydraulic motor connected to an electric generator, no electrical components are placed under water. Further, multiple turbine/pumps can be connected to a single larger hydraulic motor and a correspondingly larger generator. The pumps operate at slow speed and are therefore low in maintenance. The electric generator can be placed in a secure, sheltered building. Rivers, canals, dam discharge streams, and even sewage outflow pipes are potential candidates for this distributed pump schema.

Windmills

Similar to the hydrokinetic application described above, S-RAM technology enables the generator portion of a windmill to be relocated from the top of the tower to the base. This reduces weight at the top of the tower and permits easier long-term maintenance. Further, because of variable stroke capability, S-RAM offers the ability to operate efficiently at both lower and higher wind speeds than presently available methods.Similar to the hydrokinetic application described above, S-RAM technology enables the generator portion of a windmill to be relocated from the top of the tower to the base.
