DjuiinoStar Mini Hot Air Stirling Engine: A High Performance Pocket-Sized Working Model

IMPORTANT: SOMEONE PRETEND TO BE US TO ASK FOR REVIEWS, THIS IS A TRAP!!! NEVER WILL WE BUY REVIEWS.Designed for demonstration and amusement only. Please do NOT try to modify it. Any modification can make it damaged.Driven by the little lamp, this engine will rotate at speed around 1700-2000 RPM. It's assembled and will run within 5 minutes after opening the package provided you have a bottle of alcohol by your side.It is a MINI version which can be put into your pocket. A little bit smaller than a 300ml Coca-Cola can. But do not be confused by its size, its quality and performance are guaranteed! We've done special treatment to the machine to avoid rusting and fading; use heat treated high grade spring steel stand to ensure its stability; employ thickened quartz glass cylinder and bearing steel rod to strengthen its robustness; specially designed Lever Mechanism and Crank-rocker Mechanism makes it more "mechanical". It will definitely be a great gift to those with mechanical brains. A great desktop toy for everyone.It's also a perfect teaching tool demonstrating the process of energy exchange: the hot air in the sealed cylinder enables power piston to move continuously, and flywheel will spin at the same time; periodical air expansion and contraction makes heat energy converted to mechanical energy... Kids will be excited and curious about why. This will enlighten them to explore the world.Features:Brand: DjuiinoStarModel: DHA-BS-301Status: AssembledSpeed: 1700-2000 RPM(revolutions per minute)Material: stainless steel, bronze, bearing steel, zinc alloy, quartz glass, aluminum, HRC55 steelOverall size: 101x46x60mm/3.98x1.81x2.36in(L/W/H)Size of flywheel: 30x7mm/1.18x0.28in(Diameter/Thickness)Net Weight: 112g/3.95oz Packing List:*Engine x1*Lamp x1*Pipette x1*Spare tube x2*Spare sealing ring x2*User manual x1

Basic Stirling Engine

Basic Stirling Engine

The Stirling Engine is an External Combustion Engine (the heat source is outside the engine) and can use any available source of adequate heat or cold. It is a classic illustration of converting heat energy into mechanical work using a thermodynamic cycle similar to the well-known Carnot cycle. In this case, however, the engine needs two pistons, a small power piston and a larger "displacement piston" that also stores heat energy. This Sterling engine operates off a burning alcohol lamp that runs a piston. It is an excellent 'toy' for hobbyists or as a serious demonstration model for work or classrooms. All units are tested before shipping.

DjuiinoStar High Performance Low Temperature Stirling Engine: Rotate Hours on A Thermos; Sensitive and Quiet; Max Speed Around 800RPM!

DjuiinoStar High Performance Low Temperature Stirling Engine: Rotate Hours on A Thermos; Sensitive and Quiet; Max Speed Around 800RPM!

IMPORTANT: SOMEONE PRETEND TO BE US TO ASK FOR REVIEWS, THIS IS A TRAP!!! NEVER WILL WE BUY REVIEWS. This Stirling engine is driven by the Temperature Differential between the top and bottom panels. The simplest way to make temperature differential is placing it on a mug of hot water or on top of ice. Rotating speed highly depends on the differential: the higher, the faster. Our experiment indicates that it can rotate at a speed of around 600-1000 RPM when placed on a mug of boiled water. The Operating Temperature Differential of this model is around 27-34°F, much lower than most of the engines on the market. It can continuously rotate for 20-25 minutes on a cup of 140°F water, safer for kids. Please note when you use 140°F water (its steam actually) within a 250ml tea cup as heat source, the temperature of bottom panel is about 122°F. Our technical team has taken several effective steps to improve its performance: employ magnets to interact between power piston and displacer to eliminate mechanical friction effectively while make the whole structure simple and stable; a self-lubricated graphite power piston to reduce friction and increase robustness; a stainless steel string as connecting rod between the crank on the flywheel and the power piston to reduce more friction(less contact area). It will be an eye-catching desktop toy & gift for everyone. Features: Brand: DjuiinoStar Model: DLTD-203 Max speed: around 600-1000 RPM Operating Temperature Differential: about 27-34°F Continuous rotation time on a cup of boiling water: about 60-100 minutes Status: assembled Material: aluminum, stainless steel, graphite, sponge and acrylic Overall Size: 3.98x3.98x3.78 inch (L/W/H) Net Weight: 0.41lb Packing List: *Engine x1 *User manual x1

DjuiinoStar Low Temperature Stirling Engine: Rotate 30 Minutes on A Mug of Hot Coffee

DjuiinoStar Low Temperature Stirling Engine: Rotate 30 Minutes on A Mug of Hot Coffee

IMPORTANT: SOMEONE PRETEND TO BE US TO ASK FOR REVIEWS, THIS IS A TRAP!!! NEVER WILL WE BUY REVIEWS.Come with 30-Day Unconditional Money Back Warranty and 1 Year 100% Satisfaction Guarantee! No exaggeration to say, this is one of the most cost-effective low temperature Stirling engines in the world. Our goal is making an affordable engine with relatively high performance and great effort was taken to achieve that: we construct the transparent body of this engine with integrally-formed PC Resin which reduces cost effectively and in the meanwhile strengthens the stability and air tightness greatly and provides a clear view of the whole working process; use a self-lubricated graphite power piston instead of a glass one to reduce friction and increase robustness; a stainless steel string as connecting rod between the crank on the flywheel and power piston to reduce friction(less contact area); two little magnets on the power piston and displacer interact with each other as connecting rod to eliminate mechanical friction. This is not enough, we even print some Chinese on the exterior box to reduce more cost. Sure, this one can't be driven by warm hand as our high performance engine does. To play it, you'll have to put the engine atop a mug of hot water for 1 minute, then give the flywheel a push, then it will magically, with little put...put sound, rotate continuously for about 20-40 minutes. With boiled water, rotating speed can reach 600-800 RPM(Round Per Minute). If you need a gadget to surprise those you love, to amuse yourself, to kill time, try this one.
