HEAVY & STABLE This engine is significantly larger than most Stirling engines on the market. At 4 lbs, it is very heavy, allowing it to run stably on a table.

EXTREMELY FINE CRAFTED The base, bracket, and two flywheels are made of 6061 aluminum alloy, offering high strength, weldability, and corrosion resistance. The power cylinder and piston are made of SUJ2 material with a finely ground surface for high hardness and durability. The axle joints are connected using high-precision miniature bearings, providing stability without the need for lubrication. The power and heat cylinders are made of brass and 304 stainless steel, ensuring a long service life.

EASY OPERATION & LONG LASTING Fill the alcohol burner with 95% alcohol (recommended fuel) and light it. Let the flame heat the round-ended cylinder for about 20 seconds, then gently push the wheel, and the engine will run smoothly. It can run continuously for over 8 hours without any issues, as tested by a customer.
