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
Package include:
1 x Stirling Engine
1 x Alcohol Burner

Comfortable, Quick Drying, but Shipping Creases Were Difficult to Remove
Color: Misty Blue, Size: Large, Color: Misty Blue, Size: Large
This is a nice looking lightweight, long sleeve casual shirt. It is made of primarily polyester with a little spandex.
My husband said the shirt fit as expected and was comfortable. He noted the sleeves are a little long on him, which makes me believe it would fit a tall person nicely as my husband is of average height (5‘8“).
The shirt arrived in a vacuum pack plastic bag which caused it to have significant wrinkles (see photos). I initially tried tossing it in my dryer on the “rapid refresh“ steam cycle to see if it would remove the wrinkles. The shirt, came out with virtually no change to the wrinkles,. I then tried laundering and drying it to see if that would remove the wrinkles. Again, virtually no change. Finally, I pressed the shirt as per the care label. I mostly pressed it from the wrong side, or, in areas where that wasn’t feasible, I used a press cloth. I ended up using the “silk” setting on my iron because the synthetic setting would not remove the wrinkles.
After pressing, the shirt, looks nice. I’ve included the one picture of it after I pressed it. I’m hoping that the shirt, will be as resistant to wrinkling as it was to having the wrinkles removed!
Also, I noticed that the shirt seems to be well constructed. I’ve included one photo I took while pressing it from the wrong side that shows how nice the seams look.
Pros:
Comfortable
Fits as expected.
Attractive color
Quality construction
Launders nicely
Dries quickly
Cons:
Shipping wrinkles resistant to removal
On the upper end of price range for comparable shirts

Comfortable and stylish
I wanted something to wear in warmer weather that was full length and offered some protection against the sun when working and playing outdoors (I'm a ginger so this is a real problem for or else I turn into a lobster). I had gotten some very nice slacks that I can wear and still look professional, and this shirt complements those very well. This is a nice, loose-fitting long-sleeved shirt that you can wear pretty much anywhere outdoors and is perfect for golf or frisbee or even just corporate picnics. It's not going to overheat you if you wear this in the sun in summertime as it's loose enough that air still flows. It's only SPF 30, so I guess if you need more than that you'll either need lotion or another shirt? It's machine washable and as my pictures show I washed mine and all the wrinkles promptly disappeared, which I though was a hug win. I ordered the size I normally wear (XL) and what the sizing charts suggested and this does fit as expected. The fabric feels a little stretchy, but it's not like a pair of cotton sweatpants or anything, just enough give to allow plenty of comfort while moving around doing normal things. For less than $50 I have a nice, business casual pullover I can wear lots of places and feel dressed up enough to fit in.

Simple and not Drama claim process.
’ve had Asurion coverage for a couple of years and never needed to use it until recently, when my pool salt cell (less than two years old) stopped working. I had purchased it with an Asurion protection plan, so I contacted them to start a claim.
The process was simple and straightforward to follow. In the end, they honored the plan and covered the cost of my salt cell based on the value when I originally bought it. They issued me a gift card that I could use on Amazon for that amount.
While prices have gone up and a new cell now costs about $200 more, it was still definitely worth having the coverage. Overall, I’m satisfied with how the claim was handled.

Love this protection plan
Quick and easy. My daughter's cracked her screen on her phone, as soon as it happened I went on the app, filed the claim. Ten minutes later I received the email with the shipping lable. The following day I dropped the phone off at ups and 4 hours later I received the digital gift card. Ive filed several claims since getting the protection plan and with four kids its definitelysomething im glad to have especially since i dont have to buy a protectionplan for each item now. I have filed claims for electric scooter the stoped working for no reason, my son's phone stopped charging, my oldest daughter cracked her phone screen, my son's video game controllers up and died and each time it was quick and easy and no fuss

Don't waste your money - these people will not help you
On March 9th 2024, I purchased a MCombo Lift Chair costing $785. On the same day, through the same Amazon account (my PERSONAL account since I also have a business account), I purchased an Asurion Complete Protect policy at the cost of $16.99 per month plus taxes. About one month ago, a problem arose with the chair that required me to make a claim using the "Complete Protect" policy that I had purchased for that very item. The claim was initiated on January 1st, 2025 - On January 3rd, I received an email asking me for photographs showing the damage for which I was making a claim. I sent those photographs via email to the address provided on January 6th. On January 27th, having not received ANY response from Asurion, I contacted them via phone and was told that my purchase had been made with a business account, that it was being used for business purposes, and was therefore not covered. I assured the Asurion Representative that it was most certainly not a business use, and that the chair that I was claiming for had been purchased because I had extensive shoulder surgery done that made it impossible to get in and out of bed. After speaking (unsuccessfully) with the Asurion Rep, I then contacted Amazon Customer Service. I spoke with an Amazon Customer Service Representative on the phone who confirmed that I had in fact used my personal account to purchase the chair and the Asurion Complete Protect policy. That representative went on to send a message to Asurion on my behalf confirming that the purchase was for personal use and not business use. Asurion responded, asking me to call them with the order number for the Asurion purchase. The number I gave was the exact same order number on my order history, however, the Asurion Rep could not find it. I was finally able to discover that the order number in Asurion's system was entirely different and isn't even in the same format as an Amazon order number.
Upon the Asurion representative finding my plan, she informed me that the chair was listed as being purchased for business use (despite Amazon confirming that it was NOT) but that I should give them "a couple of business days" to resolve the issue. Five business days later, still no response and so I called them again (Yesterday - February 1st 2025)... Lo and behold, I got the same crap yet again... the purchase was listed as business use and was therefore being denied, but she promised to remove the business use commentary and put the claim through again.
Today, February 2nd, I called Amazon yet again to escalate and had to call THREE times because the first two calls resulted in me finally being connected to an Asurion representative (two different reps) and each time, the Asurion representative hung up the phone as soon as my name was mentioned.
It has become clear to me that the Asurion "Complete Protect" policy is a SCAM - they will NOT take care of your issue, regardless of how long you've been paying. I have been paying every month since March 9th last year - so they've received over $170 from me thus far, with zero other claims, and if I am able to cancel right now, I will only receive $16.99 back. All I want, is the chair that I purchased the policy for coverage of, to be repaired or replaced. Asurion are NOT helping, and are actively avoiding contact.
At this point, I am considering legal action against Asurion for fraud - perhaps even a Class Action. I'll wait and see if my issue gets resolved within the next 10 days or so.
