External combustion engine is the answer you're looking for.
There are many heat sources located outside of an engine. One of these sources is the sun in the sky.
Friction
A car engine is a heat engine, but there are various types of heat engines outside the realm of car and truck engines.
False

A heat engine can never be 100% efficient due to the second law of thermodynamics, which states that some heat energy will always be lost to the surroundings. The temperature required for maximum efficiency is the temperature of the heat source for the engine. The efficiency of a heat engine is determined by the temperature difference between the heat source and the environment.
False (APEX)
Increasing the temperature of the heat source is the most effective way to improve the efficiency of a heat engine.
On a Hyundai Santa Fe, the starter is located on the top of the engine. The engine is located next to the heat pump.
By using a heat source to boil water.
As a "heat engine", a car engine must rid itself of heat to continue. Efficiency of the heat engine depends on the difference in temperature; therefore, as the temperature outside reaches the temperature inside, the engine stops.
A combustion engine powered by fossil fuels is a common source of heat and power. It generates energy by burning fuel to produce heat, which is then converted into mechanical power.
