SUMMARY
The discussion centers on calculating the psi required to lift approximately 200 pounds to a height of 300 feet using compressed air. Key calculations indicate that a cylinder with a diameter of 6 inches and a length of 1.5 feet would require an air pressure of around 160 atmospheres to achieve the necessary thrust. The conversation highlights the limitations of compressed air as a propulsion method, noting issues such as cooling during expansion and insufficient energy density for lifting heavy weights. Alternative propulsion methods, including electric motors and hydrogen peroxide, are suggested as more viable options for achieving the desired lift.
