Contactless mass transfer system

A contactless mass transfer system, comprised of a chamber formed by alternating sections of superconductive material and electromagnetic coils, means for cooling said chamber, and means for delivering asynchronous direct current pulses to said chamber, wherein:

• (a) the interior surfaces of said chamber define a symmetrical shape;
• (b) said chamber is comprised of at least two sections, each of which consists essentially of superconductive material which has a first critical field value greater than about 10 Gauss and a second critical field value of greater than about 30 Tesla, wherein:
• 1. said sections consisting essentially of superconductive material are separated from each othger by an air gap, wherein:
• (a) each of the air gaps between two adjacent sections of superconductive material are less than 50 percent of the levitation height of the system, and
• (b) said levitation height is the average distance between the top surface of said chamber and the center of said chamber;
• (c) and electromagnetic coil is disposed within each said air gaps, wherein:
• 1. the length of the each of said sections of superconductive material is at least four times as great as the width of each of said coils,
• 2. said chamber is comprised of at least two of said electromagnetic coils disposed within said air gaps,
• 3. said means for delivering asynchronous direct current pulses provides direct current pulses to at least two of said coils in said chamber at different points in time.
