Ultra Low Temperature Stirling Engine  

High quality product designed and built in Germany

Our Stirling engine attracts plenty of attention not just among scientists. This particular Stirling engine was designed by aerospace engineers of the company CarlAero in Germany and has been optimized to work at extremely low temperature differentials. The engine even runs from the heat of a human hand and will run in reverse, when cooled. When placed on top of a cup of coffee, the engine will demonstrate how much energy is contained in the cup. Engine dimensions are: Base diameter: 100mm or 4 inches. Height 140mm or 5.5 inches.

Our engine is a great gift for any person, who likes technology or physics. Buyers keep reporting how much attention these engines attract. Many of our engines are kept running for months or even years on top of computers, fax machines, coffee machines, etc. in offices, shops or kitchens all around the world. Schools and Universities are buying our engines for educational use to demonstrate scientific facts and phenomena in a clearly visible and impressive way.

The engine comes with a description Robert Stirling's invention, it's history background and useful operating instructions. Contact us for different designs and extras like protective glass domes, liquid crystal thermometers and more.

Even television reported about the fascinating CarlAero Stirling engine design.

These unique advantages are featured by the original CarlAero engine only: 

 

  • Nano coated aluminium power piston, the ultimate combination for this application
  • This combination is graphite free and does not wear
  • The micron precision power piston is hollow and super light weight
