For several years, researchers have been working on a new way to create fusion reactors. By applying sound waves to a deuteruim-rich liquid, pressure oscillations that implode tiny bubbles filled with deuteruim vapor are created. The bubbles' violent collapse cause some of the deuterium nuclei to undergo fusion. Infact, a most recent experiment using a detector that registers neutrons and gamma rays revealed the occurrence of two separate bursts of neutrons. The first one corresponds to the 14.1-MeV neutrons of the generator, and it lasts less than 10 microseconds, after which it quickly decays. The second one corresponds to the 2.45 MeV of deuterium-deuterium fusion, and it appears 30 microseconds after the first burst, accompanied by characteristic gamma rays.
