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: Mamod SR1A Working Live Steam Roller
Review: Mamod SR1A Working Live Steam Roller
Young boys and older men who are interested in vehicles of all types are going to love the Mamod SR1A Working Live Steam Roller. This delightfully coloured model is a perfect replica of a 19th Century British Road roller and will provide males from every generation a chance to let their imagination run free. This is the perfect model for creating fun stories, characters, ideas and scenarios. Also, even though this is a boy’s toy, mums, sisters and daughters can still have fun playing and creating these wonderful stories and worlds as a family.
The Mamod SR1A steam roller comes fully assembled, so for those of you out there who love the finished model product, but aren’t really too keen on the building process, this is the perfect model for you. Father and son duos looking to either build up an existing collection, or start a new hobby together can jump right into the fun. Due to this model not needing any assembly, it’s perfect for boys who are just starting out their model collecting hobby and because it’s suitable for ages 14+ for non supervised use, the worries of mum and dad concerned about what to buy their teenage son are no more! (Also suitable for dads needing an excuse to add to their collection!)
As the pictures show, this model is exceedingly beautiful. The steam roller is simply designed using the most durable metal materials, giving the model a realistic overall look. A more modern and pristine look is given to the steam roller by it being finished with top quality colourful paint. (Get your hands on the model to help give it a more used authentic look! Real life steam rollers wouldn’t look this luxurious afterall. Of course, hardcore collectors wouldn’t dare ruin the exterior appearance of this fine piece, but that’s the beauty of the SR1A – it’s suitable for all!). The model’s dimensions are 255 x 177 x 144 mm, making it a perfect size to handle and not so big that it takes up too much room in a collector’s room.
The Mamod SR1A live steam roller is exactly that – live! The model is fully functioning as if it were an actual steam roller used on the street. The model uses solid fuel tablets (which are much safer than the fuel used for models similar to these in the past) and water. Water is poured in, the burner is lit and the steam roller is set to go. Once the model is fired up, it can easily be controlled by using the steering rod to control the front chassis. The flywheel controlling the belt to the rear wheel is powered by a brass piston and cylinder, just like a vehicle in the real world. Steam rollers in real life obviously have the ability to move forwards and backwards; Mamod have put thought into this too, giving their product the ability to travel in reverse, as well as forward. What really gives this model a special touch is the sound it makes; because of the real life components making up the steam roller, the sound made mimics that of a steam roller of its time. This is made possible by the chimney billowing steam from the model’s exhaust unit.
There isn’t a live steam roller quite like the SR1A on the market and the high quality materials making up this model ensure a longlasting product you’re going to enjoy today and for many years to come.
Review: Wilesco D5 Steam Engine Model Kit
Review of the Wilesco D5 Steam Engine Model Kit
This is a gorgeous, highly detailed steam locomotive engine that is also a working model that produces actual steam. It’s ideal for beginner steam enthusiasts, especially younger ones as it can be used by children as young as eight years old. There is always something very special about steam engines, and the way they powered the industrial age. Models like this are a good introduction to this time period, and a hand-on way to learn about history and engineering.
If you are giving this to a child, bear in mind that it will require adult supervision and is most certainly not suitable for children under three years old. It is also a working steam engine and it does turn the flywheel quite fast.
The D5 Steam Engine from Wilesco is in kit form, so you’ll have to assemble it, but that’s more than half the fun of having a working model. Assembly is straightforward; there’s an easy to follow manual, which includes illustrations so you don’t feel lost trying to work out what goes where. No soldering is needed; the components are put together by screwing them into place.
It’s an attractive model, with a faux red brick platform and chimney stack, rather like a Victorian factory might have had. The boiler has a shiny, brass effect thanks to the nickel finish, as does the oscillating cylinder and the piston. There is also the red and brass effect fly wheel. There’s an inspection glass that is the water level indicator at the front of the boiler, with a dome steam powered whistle on top. The spring safety valve is also located here, and this is where you need to insert the water using the funnel. The piston and wheel generate power, and once in motion it gets quite a speed up. This is a noisy toy, and you do get a lot of steam, all of which makes it quite exciting to watch in action. The engine used a dry fuel to heat the water for steam. There is no need for additional batteries.
It really does bring to life the age of steam, and it has identical specifications to Wilesco’s D6 steam engine. The D5 is the kit version, and the D6 comes fully assembled.
The Wilesco D5 Steam Engine Model Kit is quite light, weighing just 739g.
This is not a huge model, even though it is fully powered. But it is a good enough size for an entry level type of kit at 21 x 15 x 15 cm. It should be possible to use the engine to power small devices by connecting to a dynamo too. There are lots of possibilities, and you are only limited by your imagination. There are other Wilesco models that you can attach to the engine, and you can drive other Wilesco models from its range.
