In the experiment sterling engine,some ice is putted on top of the sterling engine as cold reservoir, and put hot water as a hot reservoir under the sterling engine. The hot water supports energy into the system as system energy. Next, part of the energy that goes into mechanical to push the engine to work, and part of it is transferred to the Q, so it goes into the ice and melts it. The cycle can keep spinning because the temperature's different is same. actually，the solar platform is one of the examples. The sun provides the hotter temperature side and gourd represents the cooler side and that difference in temperature gets the sterling engine working. The efficiency of the theoretical efficiency is pretty high compare to other heat engine.
The calculation question: The Floors /min:
By measuring the high of the floor is 5m, we calculate the that we can walk 9.3 floors in 1 min.
