NOVELTY - The molecular engine has a piston that is located inside a cylinder, the end of which rigidly abuts against a frame body. The two vessels are provided around the cylinder from its opposite ends. Each vessel has a graphene membrane with nanopores on the side of the cylinder edge. A casing is made around the vessels, and is configured to protect the outer surfaces of the vessel walls from external pressure. USE - Molecular engine.
