8+8 Medium Steam Piston Generator 14K Swatts
Optimized Medium Steam Piston Generator Design
Despite the potential of steam piston technology, there has been limited effort to optimize it for generator applications. This medium steam piston generator achieves an output of 14k swatts in an 8+8 piston configuration, with the left bank designated as master and the right bank as slave.
The drive system features a compound gearing arrangement of 2:1 + 2:1 + 3:1 + 3:1 + 3:1, followed by a half clutch before the generator, set at 0.74 for optimal load. Steam exhaust from the piston groups is managed in a 2-out/2-in configuration, which is critical for smooth operation, maintaining a relatively low exhaust pressure of 0.2 PSI. Steam input into the pistons is supplied at 59.9 PSI.
Each steam condenser is equipped with an empty buffer tank, allowing steam to occupy the void and preventing potential system clogging, although this feature is not strictly necessary.
The generator is currently powered by an electric furnace but can be easily converted to diesel or coal, provided the pump in/out configuration is mirrored for the alternative furnace. A variable valve is included to throttle coolant into the furnace and moderate temperature gain; it is currently set to 1 due to the absence of a microcontroller for automated temperature control. Testing has been conducted uncapped at boiler temperatures of 160°C and 180°C, with negligible difference in swatt output, indicating stable performance across this range.

Feel free to copy, further develop, or even claim this as your own. I’m not interested in advancing it's development it myself, and I would actually benefit if someone else tries to improve it.
