Mini Hot Air Stirling Engine Motor Model

Sunnytech, a family-owned company based in the US, follows a strict 100% zero-landfill policy for its operations. All leftover materials, including electronics, are recycled. The brand's origins can be traced back to a garage in New Jersey, where the founders promised to produce and sell only products they would be proud to use in their own homes and yards.

At Sunnytech, the "triple bottom line" - doing the right thing, doing it well, and supporting people, planet, and profit - is the guiding principle. The company actively engages with the communities it serves, driven by a belief in being outstanding stewards of the country and the planet.

Sunnytech's product range features a variety of innovative and engaging items, such as the Popular Solar Flag Light, which "lights your flag with dazzling glory," and the Alancing Toy Kinetic Art Low Temperature Stirling LT001, a great gift for science projects, classroom demonstrations, and birthday celebrations.

The Stirling engine, in particular, is a marvel of engineering, crafted with high-quality materials and elegant workmanship. It features a mirror-finished stainless steel base, a brass cylinder, a premium spring, a nickel-plated HRC55 stand and accessories, an aluminum alloy displacer piston, a glass cylinder liner, precision bearings, and bearing steel shafts. All the parts undergo surface treatment to prevent rusting.

To enhance the user experience, Sunnytech has incorporated several thoughtful design features. For instance, a special mini magnet securely attaches the alcohol lamp bottle to the Stirling base, preventing it from dropping off during operation. Additionally, the company provides extra fan kits as a free gift, allowing customers to easily DIY their own Stirling engine fan.

Recognizing the potential for breakage during shipping or use, Sunnytech includes two spare hot cylinder glass tubes and two O-rings in the package, along with a replacement video instruction for quick and easy replacement.

The Stirling engine, known as the HA001 model, operates at a speed of 1,300 to 1,500 RPM and measures 100 x 45 x 50 mm (3.93 x 1.35 x 1.5 inches), weighing 200 grams (5.6 ounces). It is constructed using steel, copper, and aluminum.

As an external combustion engine, the Stirling engine works by compressing cool gas, heating the gas, expanding the hot gas, and then cooling the gas before repeating the cycle. Sunnytech recommends using at least 95% high-grade alcohol as the fuel, as it can produce enough heat to drive the engine and generate electricity.

Sunnytech's commitment to quality, innovation, and environmental responsibility is evident in its products and business practices. By prioritizing the "triple bottom line," the company aims to create a successful and sustainable business model that benefits people, the planet, and its own profitability.
