Review of the Sunnytech® Hot Air Stirling Engine Sc02
The Sunnytech Single Flywheel Hot Air Stirling Engine is a well-crafted, fully working model which demonstrates the operational principles of Stirling engines.
What is a Stirling engine?
A Stirling engine is an external combustion engine. That is, it is an engine that gets its energy from an external heat source, in contrast to the internal combustion engine where the heat input is generated within the engine itself.
The Stirling engine was invented in 1816 by Robert Stirling, who wanted to create an alternative to existing steam engines, whose boilers could often explode because of the high steam pressures used and the strength limitations of the materials available to engineers at the time.
How does a Stirling engine work?
Like all heat engines, the Stirling turns heat energy into mechanical energy. The key feature of the Stirling engine is that it uses a fixed amount of gas – usually air – enclosed in a sealed container, with the heat consumed by the engine applied externally. This means that the engine can run on just about any heat source, including coal or gas, solar energy, chemical reaction and nuclear energy. It can also work with very low temperature differentials, which means a Stirling engine could be powered by body heat or even the steam from a cup of coffee. And because it uses heat from a constant source and does not, like an internal combustion engine, rely on a succession of explosive ignitions, the engine runs very quietly.
The heat source used in the Sunnytech Single Flywheel Hot Air Stirling Engine model is supplied by a small methylated spirit burner, which comes included, and the engine’s output is delivered – as the name suggests – by a single flywheel.
The Single Flywheel Hot Air Stirling Engine is robustly constructed from steel, copper and aluminium, and comes fully assembled, which means that you can have it up and running within minutes of taking it out of the box. Just fill the burner with meths, light the wick, let the working fluid (air) heat up for 30 seconds, give the flywheel a spin, and off it goes.
The model’s main features are:
Specification: Single Flywheel Hot Air Stirling Engine
Model No.: SC02
Size: 130mm X 80mm X 115mm
Materials: Aluminium, Copper and Steel
The Single Flywheel Hot Air Stirling Engine is an ideal collector’s item for engineering enthusiasts, as well as an engaging educational demonstration model. Most importantly, it is lots of fun. It should, however, only be used under adult supervision, and it is not suitable for children under 10 years old.
Customer reviews of the Sunnytech Hot Air Stirling Engine are consistently excellent. People who have bought it are particularly impressed by its quality and performance. In today’s world, where everything is made from plastic, the look and feel of a solid, tactile piece of high-quality workmanship is immensely satisfying. It has an elegant design, is well engineered and constructed, and runs like a dream.
Review: Wilesco D21 Steam Engine
Review of the Wilesco D21 Steam Engine
Wilesco D21 is an operating model of steam engine whistle. This Wilesco D21 is used to operate the mechanical workshops like a drill press, table saw, and grinder because this steam engine provides the output as mechanical energy. This steam engine whistle uses steam and steam is transformed by boiling water through the heat in the boiler of Wilesco D21.
How it Works
First thing first, you have to add the water in the boiler. Fill the boiler 2/3 at least and then apply boiler fill cap. That cap inserted over the boiler is also the whistle. Start burning the boiler now. You can burn the boiler through gas burner or solid fuel tablets of Esbit. Now you have to oil the piston and other parts of the Steam Engine. In the meanwhile, water gets boiled. Release steam through the piston to operate the engine and the workshop attached to it.
Appropriate Age Group
The manufacturer group Wilesco recommends this model D21 for the children of 12 years and more. But if your child is 10 years old and you feel that your child is sharper than the other kids of the same age and he can handle a bit of technicality then you can think of buying one for him as well. Wilesco Group recommends that D21 Steam Engine Whistle must be used under the direct supervision of an adult so that any discrepancies may be avoided. This product is strictly prohibited for the children of less than 36 months.
Wilesco D21 is a TUV (German Test Certificate) certified model of a Steam Engine Whistle. It has a metal body. No batteries are required to operate this steam engine model. You cannot operate Wilesco D21 by remote control. You can only run this steam engine model manually. This manual operation ability provides in-depth knowledge to a child operating this model.
Wilesco D21 has a firm body. Its body is made up of metal, and the presence of safety valve means this manufacturer does not compromise on quality. The pressure gauge can help you to be aware of the internal condition of the boiler. You can easily keep an eye on the readings to prevent any unpleasant incident. Wilesco D21 has a 500ml tank capacity which is more than enough for a child to operate its workshop using this steam engine model.
Steam Engine Model D21 by Wilesco is not very huge. It weighs only 2.7kgs, so the shipping costs are not massive. It is not very difficult for the children to handle it because the children of 10-12 years can easily handle this 3kg steam engine model by Wilesco.
There is no need to set up this Wilesco D21 because it is already assembled before delivery. When you receive this Steam Engine Model D21 by Wilesco, you may need to put on just a chimney and a couple of other things. So you have not to pay any setup cost if you purchase this Steam Engine Model.
In my opinion, the D21 Steam Engine Model is a fantastic design and a classy piece of product from Wilesco.

Review: Working Live Steam Mamod 1920’s Red London Omnibus LB1R
Review: Working Live Steam Mamod 1920’s Red London Omnibus LB1R
Oozing in class, this remarkably beautiful London bus throws collectors back to a time gone by. A world renowned icon of England to this day, the red bus of London is forever popular. Mamod does this symbol of London and the history of the British bus justice. Not straying from the real life 1920’s omnibus the model is based on, the LB1R comes in a vibrant red colour, with lovely old fashioned signs painted in yellow and red. The small details of the curved staircase, steering wheel, driver’s seat and engine give this beautiful bus detail, even down to the most minute parts.
Each LB1R is made to order from heavy gauge steel and brass. These heavy materials give the finished piece a weight of 3.8kg. The model’s dimensions are: 455 x 285 x 170mm (not quite as big as a real London bus, but big enough to admire without a microscope!) and come with fuel tables, oil and a funnel (everyone knows how annoying it is to get a gift that needs batteries, without batteries in the box. You won’t have to worry about this with the LB1R). No fear of overdoing it, though! The models are equipped with a pressure safety valve. If you’re still worried about the safety of the model, rest assured, Mamod’s switch from old fashioned methylated spirits to solid fuel tablets means that running the London steam bus is safer now than ever. The first time you’ll use the product is simple too! No faffing around, and with this particular model in the wide range of Mamod models available, no assembly is required. Just add water and off it goes. Every single omnibus is hand crafted with expertise in England.
This model is a perfect gift for a man who you would ordinarily spend hours pondering over about which gift to buy for them. The LB1R is unique – how many other men can say they were gifted a live working steam London Omnibus? Men who will enjoy this gift in particular are ones who enjoy history and English culture, men who are interested in a range of vehicles, men who appreciate finely crafted models, those who you think welcome a new hobby and last, but most certainly not least, those who are avid hobbyists and would love to extend their collection of exquisite models. Children will also benefit from this little slice of history, but bear in mind that due to the fuel and steam, it isn’t suitable for those under 14 years old to use without adult supervision.
Due to its precise craftsmanship and good quality materials, Mamod’s LB1R London bus is made to last, making it a worthy investment. Just as the real London bus has transcended through years of history and time, your own model will bring about years of delight through generations of your family. This is definitely one to be passed down from grandfather to grandson, giving the piece sentimental value, as well as monetary value.
