When it comes to safeguarding electronic devices from the effects of an electromagnetic pulse (EMP) attack, concrete is a great solution. Anything inside buildings coated with the concrete mix can be kept safe from this type of technological attack. Concrete is successful in blocking and absorbing the harmful waves created by EMPs. Christopher Tuan and Lim Nguyen, two engineers, have developed a conductive spray on concrete that can prevent an EMP from affecting electronic devices.
This invention was originally designed to melt snow and ice to provide safe surfaces for roads and bridges. The University of Nebraska has also created an aerosol on conductive concrete that can protect against EMP attacks. While the threat of an EMP attack destroying electronic devices and leading the world into an apocalyptic spiral may seem far-fetched, it's reassuring to know that there are people working to protect us from this potential danger.
