Method and device for achieving deuterium and deuterium thermonuclear fusion based on vacuole collapse

The invention relates to a method for achieving deuterium and deuterium thermonuclear fusion based on vacuole collapse. The method for achieving the deuterium and deuterium thermonuclear fusion based on the vacuole collapse includes following steps: forming vacuole by enabling fluid media which contain deuterium to cavitate; increasing the content of materials in the vacuole through ultrasonic mass transfer; enabling the vacuole to reach the wall surface of a work piece at a certain speed, and enabling the vacuole to enter a double electric layer action range; enabling gravitational collapse of the vacuole to occur under electrostatic force functions so as to achieve the deuterium and deuterium thermonuclear fusion. Additionally, the invention further relates to a device for achieving the deuterium and deuterium thermonuclear fusion based on the vacuole collapse.
