" How Does the Propulsion Turbine Work? Rather than relying on turbine blades to spin the turbine cylinder, IAS's Propulsion Turbine is designed to turn the cylinder without blades. To do that, IAS's patent-pending bladeless turbine utilizes a rocket nozzle to direct steam-a very different approach than traditional turbines."
"Rockets, widely recognized as the most efficient engines, are typically propelled by steam. Based on preliminary tests, the IAS-designed rocket nozzle 99 percent efficient, and its net thermal efficiency is above 75 percent when traveling at 50 percent of the velocity of the steam exiting the nozzle. This efficiency continues to increase as the velocity of the rocket nozzle exceeds 50 percent of the velocity of the exiting steam."
"Traditional turbine performance relies upon the environment within its blade chambers. If steam condenses on the blades, a sharp drop in efficiency and damage to the turbine can be the result. Traditional multi-stage turbines require dry, high-quality steam. This is more expensive to produce and maintain. IAS's new turbine is structurally unaffected by low quality steam."
"Hero's Engine is today a generic name for any device which propels itself by shooting steam from one or more orifices. These devices are also known as Eolipiles."
"The two engines in the picture at the left are from the apparatus collection at Yale University. After filling the sphere with water, a flame is applied to it until the water boils, and the device begins to rotate."
