The "One-Earth-Altar" consists of a winged triptych of double walled
high-grade steel (glas bead - blasted) and perspex sized 7.32 m
in length, 4.07 m in height and 0.15 m in depth with 7000 earth-books
arranged in pockets of 8 columns and 23 rows (17 in each wing), each
pocket containing 43 earth books.
As the weight of the
earth-books is expected to sum up to several tons the centre part of the
altar (3.66 m x 4.07 m) is anchored into the bottom concrete and into
the background apsis with 5 anchors each.
The closable wings (1.81 m x 2.74 m)
are mounted to the centre part of the altar with tape hinges. Statics are
calculated for 7 metric tons.
