An insulated glazing unit including a first glass element and a second glass element having congruent shapes. The insulated glazing unit also includes a plurality of elongated spacers disposed between the first glass element and the second glass element to space the first glass element from the second glass element. The spacers are in rolling, line contact with a surface of one or both of the first glass element and the second glass element, and each spacer is elongated along an axis. The spacers are oriented on the surface such that the axis of each of ...

1. An insulated glazing unit comprising: a first glass element;a second glass element, the first and second glass elements having congruent shapes; anda plurality of spacers disposed between the first glass element and the second glass element to space the first glass element from the second glass element, each of the spacers elongated along an axis,wherein the spacers are in rolling, line contact with a surface of one or both of the first glass element and the second glass element such that the spacers are configured to roll about their axis in line contact with the surface, andwherein the spacers are oriented on the surface such that the axis of at least one of the spacers is tangent to an imaginary circular line superimposed on the surface, and at least another of the spacers is tangent to the same imaginary circular line or a different imaginary circular line having a common center with the first imaginary circular line. 2. The insulated glazing unit of claim 1, wherein the spacers are arranged along a plurality of imaginary circles superimposed on the surface, and wherein the circles are concentric with each other. 3. The insulated glazing unit of claim 2, wherein the imaginary circles have uniform radial spacing from the common center. 4. The insulated glazing unit of claim 3, wherein the spacers arranged along each of the imaginary circles are separated by arcs of substantially equal length. 5. The insulated glazing unit of claim 2, wherein the center of the circles is aligned with a centroid of the first glass element. 6. The insulated glazing unit of claim 2, wherein the center of the circles is offset from a centroid of the first glass element. 7. The insulated glazing unit of claim 1, wherein a space is defined between the first glass element and the second glass element, the insulated glazing unit further comprising a seal coupled to the outer peripheries of the first glass element and the second glass element to seal the space, and wherein the space between the first and second glass elements is evacuated. 8. The insulated glazing unit of claim 1, wherein at least some of the spacers are temporarily affixed to at least one of the first and second glass elements. 9. The insulated glazing unit of claim 1, wherein at least one of the spacers is defined by a column-shape that is curved or chamfered. 10. The insulated glazing unit of claim 1, wherein at least one of the spacers is a non-cylindrical surface of revolution. 11. The insulated glazing unit of claim 1, wherein the spacers have a surface of revolution and at least one of the spacers has a stop interrupting the surface of revolution to limit rolling motion of the spacer on the surface. 12. The insulated glazing unit of claim 1, wherein an interior of each of the spacers is hollow. 13. The insulated glazing of claim 1, wherein at least one of the spacers is elongated and the at least one spacer is curved in the elongated direction. 14. A method of manufacturing an insulated glazing assembly having a first glass element and a second glass element, the method comprising: spacing the first and second glass elements from each other with spacers, the spacers having rolling, line contact with a surface of one or both of the first glass element and the second glass element, each of the spacers elongated along an axis such that the spacers are configured to roll about their axis in line contact with the surface; andorienting the spacers on the surface such that the axis of at least one of the spacers is tangent to an imaginary circular line superimposed on the surface, and at least another of the spacers is tangent to the same imaginary circular line or a different imaginary circular line having a common center with the first imaginary circular line. 15. The method of claim 14, further comprising aligning the spacers along a plurality of imaginary circles superimposed on the surface, and wherein the circles are concentric with each other. 16. The method of claim 15, further comprising arranging the spacers so that the imaginary circles have uniform radial spacing from the common center. 17. The method of claim 14, further comprising sealing the first and second glass elements in spaced relation; andevacuating the space between the first and second glass elements. 18. The method of claim 14, further comprising temporarily affixing at least some of the spacers to the surface. 19. An insulated glazing unit comprising: a first glass element;a second glass element, the first and second glass elements having congruent shapes; anda plurality of elongated spacers disposed between the first glass element and the second glass element to space the first glass element from the second glass element, each of the spacers elongated along a first axis and having a second axis perpendicular to the first axis, the second axis of each of the spacers defining a rolling direction of the corresponding spacer such that the spacers are configured to roll about their first axis in the rolling direction while maintaining line contact with the surface,wherein the spacers are in rolling, line contact with a surface of one or both of the first glass element and the second glass element, andwherein the spacers are oriented on the surface such that the rolling direction of at least one of the spacers differs from the rolling direction of at least another of the spacers. 20. The insulated glazing unit of claim 19, wherein the second axes of the spacers are oriented toward a common point.
