The greatest threat to the functioning of the state is the attack of the EMP, with the help of arms generating electromagnetic pulse. Such a weapon can destroy all electronic devices, turning the country back to the Middle Ages. Impulse will erase all the money on the bank accounts, power stations, water supply, communication, etc. will stop operating.
Protection from such a scenario requires the use of adequate shielding, but providing it to everyone is very complicated and costly. But the two Nebraska researchers have developed technology that can help.
Christopher Tuan and Lim Nguyen have created a cheap mix of concrete that can provide excellent protection against electromagnetic pulse, shielding electronic devices. The invention is a modification of the previous idea of engineers, which is self-warming concrete, which can safely melt snow and ice. Engineers planned to create safer roads and bridges, thus preventing collisions of cars caused by slippery roads.
Unusual properties of the concrete protecting against electromagnetic radiation are obtained by the use of magnetite, iron ore magnetic properties, which absorbs radiation. Concrete is also enriched with carbon and metal additives that further increase its absorption.
