University of Manchester mathematicians have developed the theory for a ’cloaking’ device which could protect buildings from earthquakes. By cloaking components of structures with pressurised rubber, powerful waves such as those produced by an earthquake would not ‘see’ the building; they would simply pass around the structure and thus prevent serious damage or destruction. The building, or important components within it, could theoretically be ‘cloaked.’
This ‘invisibility’ could prove to be of great significance in safeguarding key structures such as nuclear power plants, electric pylons and government offices from destruction from natural or terrorist attacks.
