US Patent 7618216 - CNT wire earthquake proofing

http://www.freepatentsonline.com/7618216.html

Carbon nanotubes have been proposed for many years to strengthen materials. This patent proposes a system of using webs of carbon nanotube wires in housing materials to protect from earthquake damage. Claim 1 reads:

1. An apparatus to reduce damages to structures due to earth movement comprising:

a central slab;

a plurality of neighboring slabs adjacent to the central slab, each slab being spaced apart from each of the other slabs; and

at least one carbon nanotube wire embedded in each slab, wherein the at least one carbon nanotube wire embedded in the central slab is connected to the at least one carbon nanotube wire embedded in a neighboring slab, wherein there is a structure on the central slab, and there is another structure on at least one other slab, and wherein the apparatus is configured to reduce damages to the structure due to earth movement.
