US Patent 7618216 Faultline fearless nanotube homes

A structure to strengthen a house against earth movement, such as earthquake. The house can be known as the central house. In one embodiment, there is a slab under the house. The central house has a number of neighboring houses around it. There is also a slab under each of the neighboring houses. The slab under the central house can be known as the central slab, and the slabs of the neighboring houses can be known as the neighboring slabs. At least one carbon nanotube wire is embedded in each slab. The at least one carbon nanotube wire in the central slab is connected to two of the carbon nanotube wires in neighboring slabs.
