Abstract: A system for maintaining the depth of injected vapor in an entrochemical system is disclosed. The vapor transfer pathway terminates in the chamber containing high concentration solution underneath the surface of the solution. In one example the vapor transfer pathway is passively adjustable, using a flotation device to maintain the depth of its end. Another example uses an active, actuated system to maintain the depth of the end of the vapor transfer pathway. The energy for controlling the depth of vapor transfer pathway is minimized by passive methods and derives from the heat of mixing of the vapor and the high concentration solution.

Abstract: A device is provided which translates the chemical energy released by the candles into a smooth movement of a platform floating within a pool of liquid and utilizing a virtual axle.

Abstract: A levitating mount apparatus is provided which utilizes a permanent magnetic male and female levitation support as described in U.S. Pat. No. 7,501,922. The mount has two general forms. In one general class, the mount is attached to an axle aligned with the axis of symmetry of the female part of the permanent magnetic male and female levitation support. In the second class, the female part of the permanent magnetic male and female levitations support is attached to the bottom of the mount, and no axle is utilized. The mount is stabilized using a stationary support structure which has limited contact with the levitating portion of the apparatus at the top of the mount.
