Crafted from durable steel and glass, it requires no batteries and operates quietly with graphite lubrication. Ideal for STEM education, office decor, or as a unique gift, it demonstrates thermodynamics in a stylish, hands-on way. ## Description This low temperature stirling engine,runs on a hot cup of water(Do not put it above a candle or other fire) The engine's speed depends entirely upon the temperature difference between the hot side and the cold side. In the case of using a cup of hot beverage, not only is the engine transferring the beverage's heat to the surrounding air, there are air currents constantly crossing the top (cold) plate. The differing temperatures will cause the engine to slow or speed according to the net difference between the two plates. For some extra fun, you could obtain a USB-powered cup warmer and place engine on that. After the warmer finally made it to full temperature, the engine will chug along like a champ. Attention: 1.If there is a little noisy, ONLY use a little graphite dry lube or a pencil quieted it down nicely. 2.Do not use oil to lubricate,which will mix with dust in the air, and become a oil-dirt, finally make the friction to be even bigger.The stirling engine can't run smoothy. Size: 102 X 102 X 125mm Material: Steel and Glass Speed: up to 180-250 RPM Start Temerature Difference: 20 ℃ Weight: 236g Package Included: 1 x Low Temperature Stirling Engine ## Features - This low temperature stirling engine,runs on a hot cup of water(Do not put it above a candle or other fire) , could be a great conversation starter at work and unique gift to families or friends or for class demonstrations.It is almost ready to run: after the installation, put it on a cup of hot water or Ice water, wait a couple of seconds, gently flip the wheel,then it will run itself. - Basically you can run this engine up to 20 minutes with a cup of warm water (the engine must be cool). The bigger the temperature difference between the top and bottom plates the higher RPM you will get. This works best with a hot cup of water underneath and an ice cube in a plastic bag on the top (there is plenty of room for one ice cube on top). - Durable, well made, sytlish, and adjustable.Very fantastic craftsmanship, made with Metal Alloy - If there is a little noisy, ONLY use a little graphite dry lube or a pencil quieted it down nicely. Do not use oil to lubricate,which will mix with dust in the air, and become a oil-dirt, finally make the friction to be even bigger.The stirling engine can't run smoothy. - Size: 102 X 102 X 125mm ,Material: Steel and Glass,Weight: 236g ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01B2MF3MY | | Age Range Description | Baby | | Battery Description | No batteries required | | Best Sellers Rank | #254,120 in Toys & Games ( See Top 100 in Toys & Games ) #2,230 in Educational Science Kits | | Brand Name | Usmile | | Customer Reviews | 4.4 4.4 out of 5 stars (55) | | Educational Objective | HIGH | | Item Dimensions | 8.39 x 5.71 x 4.49 inches | | Item Highlight | Physics Gift,Desk Decoration,STEM inspiration, Education Toy for tech lovers,Run Off the Temperature difference | | Item Weight | 1.3 pounds | | Manufacturer | Usmile | | Manufacturer Part Number | 43227-871 | | Manufacturer recommended age | 14 - 14 years | | Material Type | Stainless Steel, Glass | | Model Number | 43227-871 | | Number of Items | 1 | | Size | Large | | Theme | Stirling | | UPC | 735980948720 | | Unit Count | 1 Count | ## Images ![Low Temperature Stainless Steel Stirling Engine Generator for Education - Image 1](https://m.media-amazon.com/images/I/61QvycrrwZL.jpg) ## Frequently Bought Together - Usmile® Low Temperature Stainless Steel Stirling Engine Generator Desk Models Education Toy Model Run Off The Temperature Difference - Sunnytech Low Temperature Stirling Engine Motor Steam Heat Education Model Toy Kit For mechanical skills (LT001) - DORAMI Clear Solar Power Crookes Radiometer Sun Light Energy Spinning Vanes --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.au/products/23424611-low-temperature-stainless-steel-stirling-engine-generator-for-education](https://www.desertcart.com.au/products/23424611-low-temperature-stainless-steel-stirling-engine-generator-for-education) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-10-29*
