Cold Fusion

Researchers at Purdue have confirmed nuclear fusion in a tabletop experiment. The researchers fired ultrasound at deuterated acetone, which contains deuterium instead of hydrogen, in a chamber flooded with neutrons. As expected when high-frequency sound waves hit the liquid, cavities and bubbles were formed in the liquid in a process known as acoustic cavitation. What wasn't expected was the formation of perfectly spherical bubbles which implode with greater force than irregularly shaped bubbles. The implosion produced high temperatures and light in a phenomenon called sonoluminescence, which fused deuterium atoms together as they're fused in stars. Is it fusion?

The researchers have estimated the temperature within the imploding bubbles reach upwards of 10 million degrees Celsius, with pressures of 1 billion earth atmospheres. The experiment also resulted in the emission of neutrons of 2.5 MeV and the production of the radioactive tritium -- both of which are expected from nuclear fusion. All they have to do now is harness the energy that is being produced by the fusion reaction. If they can do that, I think I'll start believing in the whole cold fusion thing. I'm actually rooting for them.
