When you think about engines, probably you first think of cars and other vehicles. However, there are several uses of engines. Unless you have an interest in alternative power and heat sources, it is not particularly known to the public. Reason being is this type of engine has some impracticalities that make it unsuitable for common use. Although there are many advantages to using these engines, no one has come up with a way to make them more cost effective. There are also issues with the size power, torque and gas used in its operation. Many companies however continue to research and innovate current technologies to make them more efficient. Listed below are 10 ways in which the stirling engine has been applied, both in the past and the present
