According to the kinetic theory of gases, the molecules in the air in a particular room must have some kinetic energy which depends on the temperature in the room. In order to extract this energy to do mechanical work I would need for the object receiving this energy to be at a much colder temperature. This is best explained by

This scenario is best explained by the Second Law of Thermodynamics, which states that heat will naturally flow from hotter objects to colder objects, and that it is impossible to extract all of the heat energy in a system to do mechanical work. Therefore, in this situation, some of the kinetic energy of the molecules in the air will be lost as heat to the colder object, and it is impossible to fully convert this energy into mechanical work.
