.. How does a thermoacoustic Stirling engine work?
The thermoacoustic engine is a particular type of Stirling engine, which has been proposed as an electricity generator for space travel using radioisotopes as the heat source, among other applications.. The thermoacoustic engine works by converting sound waves into motion. The sound waves are generated by heating one end of a 'stack' of coiled material and allowing the other end to remain cool.

Beautiful appearance and high quality. The main body is made of high quality metal, which is firm and strong.
.The hot cylinder is made of glass, high hardness, high speed and long time running without wear.
.The pursuit of the details, the overall fine grinding, touched very smooth, very metallic and modern technology, to achieve a dual combination of texture and beauty.
.Modular parts are shipped and it's fun to do it yourself.
.Installation method: Install the hot cylinder with the short screw on the beam. When installing, the direction of the cylinder should be in line with the beam; the long screw should pass through the beam hole and then pass through the bracket. When fixing the screw, it must be firm; push the piston gently into the cylinder. After the outer cylinder and other pistons are pushed forward, gently pull the lower piston back and forth by hand to check whether it is flexible. If it is not flexible, it can be lubricated with lead powder. It is forbidden to add any lubricating oil to the piston part; the large flywheel is mounted on the measurement position. Install the connecting rod to the positioning of the flywheel. Use a cotton swab to apply a little oil on the two positioning points. Do not add oil to other parts. Place the metal magnet piece on the bottom of the alcohol bottle so that the magnetic alcohol bottle will be firmly attached. On the engine base.
.This product belongs to the external combustion engine, which makes the external combustion of the fuel heated, and the expanded air (helium or hydrogen) acts as a medium to move the piston. The expanding gas is cooled in the cold cylinder, and such a cycle is repeated.
.The fuel is made of high-quality steel wire, which has ultra-high thermal release performance and is safer.
.The engine is placed horizontally during operation, and the alcohol lamp is added to approximately 2/3 of the 95% alcohol and placed under the hot cylinder.
.To ensure safety, ignite the alcohol lamp.
.Continue to heat the hot cylinder for 2 to 3 minutes, one hand presses the engine base plate and the other hand quickly dials the large flywheel engine to run.
.The product is suitable for people over 14 years old.
.Tips: Be careful not to be burnt by high temperature during the operation.
.Do not touch any part that has been fired to avoid burns.

Comfortable and Easy to Wear Daily
Size: 2 Little Kid, Color: Navy/Blue
My daughter has been wearing these navy/blue shoes since the weather has been less rainy and more sunny. They are great for outdoor play, especially on days when it's warm outside. The knit mesh upper keeps her feet from overheating, and the cushioned insole feels supportive without being stiff. At size 2, the fit is accurate and the width runs a bit roomy, which gave her some growing room without feeling loose. The slip-on design with elastic laces and pull tabs is a real plus. She can get them on and off without any help, which she loves. The shoes are light enough that she barely notices them during long active days. My one small complaint is that the sole feels more like firm foam than rubber, so they can be a little slippery on smooth indoor floors. For the price, these deliver solid everyday value. They look good, hold up well to regular use, and my daughter reaches for them first most mornings. Pros: - Breathable mesh keeps feet cool - Easy slip-on design with elastic laces and pull tabs - Lightweight and comfortable for all-day wear - Accurate sizing with a roomy width - Durable for the price Cons: - Sole can be slippery on hard smooth surfaces - Limited outsole grip compared to rubber-soled shoes

Great kids' shoe — easy on, comfy all day
Size: 3 Little Kid, Color: Pink/Lavender
My kid has been wearing these for a few weeks now and I'm genuinely impressed with how well they've held up. The knit mesh upper keeps feet cool and comfortable during long days at school and outdoor play, and the cushioned EVA midsole does a great job absorbing impact. What really won me over is the slip-on design with elasticated laces and dual pull tabs — my child can put them on and take them off completely independently, which is a huge win. The fit is snug but not tight, and they run a bit roomy in width, which is great for kids with wider feet or those who need a little growing room. At $32, the quality feels solid for the price. Lightweight, breathable, and easy to wear — these check all the boxes for an everyday kids' shoe.

Cute, Comfortable, Light-Weight Shoes, Perfect for School
Size: 11 Little Kid, Color: Pink/Lavender, Size: 11 Little Kid, Color: Pink/Lavender
These have turned out to be great everyday shoes for my 5 year old. She normally wears a size 10, but since that size wasn’t available, I ordered the 11 expecting her to grow into them. I was pleasantly surprised that they already fit her pretty well. There’s still a little extra room in the toe area, but the shoes fit securely around her ankles so they don’t feel loose or slip off while walking or playing. She says they’re very comfortable and loves how easy they are to slip on by herself. The lightweight design is nice for everyday wear, and they’ve held up well so far despite being worn almost daily. They've become her favorite shoes to wear! Also the pink/lavender color is really pretty in person. Overall, I’m very happy with them and would order again.
