Good point, Herman.
Water boils at 100 centigrade (212 F) at standard air pressure - 1 atmosphere. It will boil at a much lower temperature if you climb to the top of Everest. The rule of thumb is the boiling point drops by 1 degree F for every 500 feet. So at the top of the world, water is boiling at around 160 F. Can't make a decent cuppa.
Under pressure, the boiling point is raised. Approx 40 degrees F for every atmosphere (15 psi). Hence, the old pressure cooker could cook faster because the water is much hotter.
Perhaps the original poster means 180 C?
