Former engineer used a computer processor to drive a Stirling engine

Modern and high-performance central computing devices are known not only for their ability to handle complex tasks, but also for generating significant amounts of heat energy during operation. This was reported by Zamin.uz.

Former Microsoft engineer and one of the lead developers of the Windows operating system, Dave Plammer, decided to use this heat energy in an unexpected way. He powered a Stirling engine, invented in the 19th century, using the heat released by a 32-core AMD Threadripper 3970X processor.

International technology publications reported on this experiment. During the scientific test, a Stirling engine with a piston was installed on the part of the computer system board where the microchip assembly is located.

This device has the ability to convert the heat generated by the computer's operation into mechanical energy. When the system heats up, a special coupling absorbs the thermal energy, moves the piston, and begins to rotate the flywheel.

This process demonstrated the successful compatibility of modern high technologies with an engineering idea from two centuries ago. The Stirling engine was first patented in 1816 and belongs to the category of external combustion engines.

Although this technology is currently used in some energy and industrial sectors, in everyday life it often serves as an educational tool to illustrate physical processes. In the video published by the engineer, he initially rotates the flywheel by hand, after which the engine continues to operate independently, powered solely by the heat emitted from the computer.

According to specialists, such small engine models can be purchased at low cost from major retail outlets. They are so sensitive that they can even operate using the heat from a single cup of hot coffee or the warmth radiating from a human hand.

Extremely powerful processors like the AMD Threadripper serve as a stable heat source sufficient for continuous operation of such devices. It should be emphasized that this experiment was conducted not as a new method of computer cooling, but rather as an engaging scientific demonstration.

Dave Plammer did not provide exact figures on how low the processor temperature dropped or what impact this device had on the system's overall performance. Nevertheless, this case draws attention to the issue of recycling excess energy generated by computer technology.

At present, various large-scale projects exist that redirect the heat emitted by data centers and powerful servers toward heating buildings or warming water. Plammer's experiment demonstrated the simplest and most visual form of converting thermal energy into mechanical motion.

Such approaches may in the future inspire new ideas for improving the energy efficiency of electronic devices.
