People have used the force of an explosion for a long time. But this force found only one use today-destruction. Now scientists have forced the explosion to work for creation. The explosion moves mountains, builds dams, digs canals and smooths out river beds. EGE - this is also an explosion, but only a completely special, electric explosion. The place of its discovery is the Soviet Union. It was first seen and scientifically founded by the inventor Lev Yutkin. By experimenting, he placed electrodes in a tank of water and charged them with a current from a high voltage capacitor battery. A bright spark sputtered in the water, an explosion thundered, and instantaneously a shock wave arose. Here, a steam-gas bubble formed around the electrode. The unexpected phenomenon was called EGE, which means electrohydraulic effect.
