Kulcar's dual turbo fans pumps hot and stale air out of your vehicle when parked under hot sun. When parked under a blazing sun, the temperature inside your car can easily exceed 190 degree F. Installed with proper units of Kulcar, Kulcar guarantees to reduce the temperature inside your car by no less than 18 degree F. Kulcar is powered by the cleanest energy directly from the sun and backed by a ten-year solar panel warranty. By actively refreshing the air inside your car, Kulcar expels hot, odorous air and harmful fumes from your vehicle when parked in the sun. The panel is designed to allow adjustment for best angle to face directly toward the sun for optima efficiency. Kulcar's turbo fan design introduces no less than 40 cfm of fresh air into your car continuously to keep the interior of your car cooler and protect the interior materials from heat damage.
Use this little stainless beauty to teach teenagers and older students how heat engines work
Then keep it on your desk, where you deserve to have it! This low-temperature-differential Stirling engine is beautifully machined.
It works with 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.
It measures 5-3/4" tall with a 3-5/8" dia flywheel and a 3-1/2" dia x 7/8" tall base.
DSTAR engines has a complete line of external heat engines using similar parts so each item can be used in a educational setting and have them look as a complete set. If you need support for any DSTAR engine just contact DSTAR.

It is a amazing and fantastic product at this price,it can be a great gift to your families or friends. It also can be used for teaching purpose. Many of our customers comes from chool,colleague,etc. As the Glass cylinder parts in the stirling is EASY BORKEN, So we put extra one set spare parts inside for you, if anything broken, you can replace it easily and fast. but we don't send extra glass parts if one set is broken. How it works? This is traditionally known as an external combustion engine in contrast to an internal combustion engine where the heat input is by combustion of a fuel within the body of the working fluid. Unlike the steam engine's use of water in both its liquid and gaseous phases as the working fluid,the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle.

Many of our ustomers comes from school,colleague,etc. What is the stirling engine? A Stirling engine is a heat engine that operates by cyclic compressionand expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.The engine is like a steam engine in that all of the engine's heat flows in and out through the engine wall. How it works? This is traditionally known as an external combustion engine in contrast to an internal combustion engine where the heat input is by combustion of a fuel within the body of the working fluid. Unlike the steam engine's use of water in both its liquid and gaseous phases as the working fluid,the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle.
