The invention provides an improved power device using environmental thermal energy. The power device comprises a cylinder, a piston, an air injection plug, an air inlet pipe, an air inlet door, an exhaust pipe and an exhaust valve, wherein the cylinder is provided with an air inlet, an exhaust hole and an air injection plug mounting hole, the piston is built-in in the cylinder and is used for providing power to outside, and the air injection plug is arranged at the air injection plug mounting hole of the cylinder and is used for providing high pressure normal temperature gas; the air inlet pipe is arranged at the air inlet of the cylinder and is used for providing an air inlet channel, the air inlet door is used for being started and closed to realize that the air inlet pipe is connected or closed, the exhaust pipe is arranged at the exhaust hole of the cylinder and is used for providing an exhaust channel and the exhaust valve is used for being started and closed to realize that the exhaust pipe is connected or closed. According to the power device provided by the invention, liquid state gas is served as a working medium, and the piston is pushed to work by the pressure release generated by absorbing heat to gasify and expand through liquid gas; the power device has the characteristics of no pollution and simple structure. On this basis, the invention further provides an improved power system using the environmental thermal energy.
