Toys could be divided into several different types according to its purpose, some of them are for appreciation, some requires hobbyists initiative to gain self-satisfaction. While very rare of them like Low Temperature Stirling Engine which can bring you entertainment and really teach you something. It could be a decoration if quietly standing on the table. When putting it above a cup of hot or cold water, something unimaginable happens!
Inheriting the same working principle from engine motor, the Stirling engine can creates kinetic energy where there is a temperature difference. If you’re fond of doing physical experiment, the engine allows to turn the kinetic to electricity. For instance, Low Temperature Stirling Engine could be driven by hot vapor if you put it above a cup of hot coffee. Then it starts rotating once you slightly touch the wheel, and the gold flywheel will rotate with very fast speed continually.
In order to achieve adequate efficiency and performance at low temperature differentials, the design of the heat converting components should focus on reducing temperature drops as much as possible to decrease loss of energy, such as gas flow friction, conduction losses, and gas hysteresis losses. The Low Temperature Stirling Engine is beloved because of pretty low cost materials as well as energy consuming.
As a matter of fact, Low Temperature Stirling Engine could be high-appreciative decoration putting on table in study or living room, cause the golden coating and exquisite structure makes it pretty elegant. As far as I’m concerned, the engine is beyond many toys on the market. It’s not only a decoration or a present, but also scientific toy to teach young children how to make a simple engine and how it works.
All in all, the Low Temperature Stirling Engine is endowed with multiple functions. It’s a teaching tool and also a nice present for friends and family member, and even a nice prize for students. Remember, you can easily operate it if there is hot water, ice water, a combination of hot water with ice cubes, or a hair dryer. The bigger the temperature differential the faster it runs.
