In one aspect, the invention provides a method for rotating an impeller device. Said method comprises (a) positioning at least one ejector tube to eject a working fluid onto the impeller device; (b) locating a kinetic droplet in an ejector tube; (c) introducing a charge of vapor into the ejector tube behind the kinetic droplet so that expansion of the vapor in the ejector tube causes the kinetic droplet to accelerate out of the ejector tube and to impinge on the impeller device; and (d) repeating steps (b) and (c) in a synchronized fashion. |
