Pneumatic motor low engine temperatures. The Pneumatic Quasiturbine engine is a compressed air pistonless rotary engine using a rhomboidal-shaped rotor whose sides are hinged at the vertices. The Quasiturbine has demonstrated as a pneumatic engine using stored compressed air It can also take advantage of the energy amplification possible from using available external heat, such as solar energy. The Quasiturbine rotates from pressure as low as 0.1 atm (1.47psi). Since the Quasiturbine is a pure expansion engine, while the Wankel and most other rotary engines are not, it is well-suited as a compressed fluid engine, air engine or air motor. Armando Regusci's
Molecular motor Molecular motor Molecular motors are biological molecular machines that are the essential agents of movement in living organisms. In general terms, a motor is a device that consumes energy in one form and converts it into motion or mechanical work; for example, many protein-based molecular motors harness the chemical free energy released by the hydrolysis of ATP in order to perform mechanical work. In terms of energetic efficiency, this type of motor can be superior to currently available man-made motors. One important difference between molecular motors and macroscopic motors is that molecular motors operate in the thermal bath, an environment
