Stirling Engine Kit Motor Model DIY Educational Steam Power Toy Electricity Learning Model
Stirling engines are unique heat engines because of their theoretical efficiency is almost equal to the theoretical maximum efficiency,
Called the Carnot cycle efficiency. The Stirling engine is heated by gas expansion, cold contraction generate power.
Description:
Name:Stirling Engine Hot Air Model
Material:metal,glass
Color:gold
Size:165x87x95mm
Features:
-This is an external combustion engine in which the fuel is burned continuously, and the piston is moved by the expansion of air (or helium or hyd rogen) as a medium, and the expansion gas is cooled in the cold chamber, and the cycle is repeated. Only a small alcohol lamp, you can make it fast rotation and strong power.
-As the external combustion engine to avoid the traditional internal combustion engine of the explosion to do work, in order to achieve a high efficiency, low noise, low pollution and low operating costs.
-The biggest advantage of the external combustion engine output and efficiency from the influence of altitude, very suitable for high altitude areas.
- Aerodynamics are rich in knowledge of physics, single cylinder combustion engine. Engine principle is intuitive, educational toys, teaching experimental equipment can effectively cultivate children's interest in learning can also be used for classroom teaching, more intuitive and easy to understand.
Instructions:
-The engine model on the horizontal position by hand toggle the flywheel to see if smooth, if there is a strong sense of raw astringent, check the connection rod is normal, whether the cylinder oil and dust, and if so, please use toilet paper to erase Not smooth. Toggle the flywheel feel pressure rebound within the cylinder body is a normal phenomenon, the cylinder is sealed.
-The packing bag of alcohol lamp cotton wear into the metal cap lamp.
-Please go to the pharmacy to buy 95% purity alcohol, anhydrous industrial alcohol better. Fill the alcohol lamp to less than two-thirds.
-Alcohol lamp to the alcohol lamp, at the premise of ensuring safety, ignite the alcohol lamp about 2 minutes after the flywheel, until the flywheel automatic operation so far, the whole process of heating, hands may not touch.
-Led lights can be directly into the generator output interface, if not inserted, the exchange can be positive and negative, led a long foot for the cathode.
Note:
-There will be the operation of steam,when the steam too much time, the engine will stop working,
inside and outside the needle often set aside to reduce friction
-Do not rotate the nut too tightly, otherwise the glass is broken, if the piston is cracked,
can be bonded with glue.
-The alcohol lamp wick do not touch the glass, do not get too tight ring
-Pulling the piston connecting rod can not force the front end, because the front
end is easy to break

Best biltong tasted to date
Biltong depot produces the best biltong I have tasted to date . I was ordering the 8oz slabs till now but I am going to order these instead . Same taste but the convenience is that it’s already been thinly sliced . The only thing I could say is a negative is it has too much sodium which could be reduced.

Actual biltong that is not dried to the point of being jerky
If you are like me, you have ordered biltong as slabs and pre-sliced slabs from a bunch of companies promising the real deal. Too many of those companies trim the fat or dry things out so much that it might as well be American beef jerky with coriander added to the spice blend. This just arrived and we opened the bag not expecting anything different honestly. I am sitting here eating it and logging on to write a review because this is finally the real deal. I wouldn't say that it is wet, but it isn't American jerky level dry either and there is good fat on the pieces. It's pricey, and there was a dry piece or two and a bit of fat that hadn't been properly flavored, but it is the next best thing to a freshly sliced wet and fat slab. If you can afford this treat, don't waste your money on the less expensive stuff -this is what you are missing.

Privacy is what I was looking for and that’s what I got !!!
Color: Black, Size: Wheel-132''
Right now, I am in a shared room and it is perfect because I can block out and have some privacy for my clients. I purchased the six panel and realized it was too much so I was able to only set up three panels and it was just enough room for my clients to walk through to my side, but also have a sense of privacy. It’s not heavy at all very lightweight but durable at the same time. Because of the wheels, I’m able to easily glide it across the floor. This is a really good product. I didn’t need my husband to help me set it up though LOL
