LOS ANGELES — Brian Kappus, a physics graduate student at U.C.L.A., tipped the clear cylinder to trap some air bubbles in the clear liquid inside. He clamped the cylinder, upright, on a small turntable and set it spinning. With the flip of another switch, powerful up-and-down vibrations, 50 a second, started shaking the cylinder.
A bubble floating in the liquid — phosphoric acid — started to shine, brightening into an intense ball of light like a miniature star.
The shining bubble did not produce any significant energy, but perhaps someday it might, just like a star. A few small companies and maverick university laboratories, including this one at U.C.L.A. run by Seth Putterman, a professor of physics, are pursuing quixotic solutions for future energy, trying to tap the power of the Sun — hot nuclear fusion — in devices that fit on a tabletop.
Dr. Putterman’s approach is to use sound waves, called sonofusion or bubble fusion, to expand and collapse tiny bubbles, generating ultrahot temperatures. At temperatures hot enough, atoms can literally fuse and release even more energy than when they split in nuclear fission, now used in nuclear power plants and weapons. Furthermore, fusion is clean in that it does not produce long-lived nuclear waste.
I dont see the peer-reviewed seal of approval. But they stole my idea of 300 foot ionic breezes from sharper image. Study Paper

Evidence Bubbles Over To Support Tabletop Nuclear Fusion Device Whereas conventional nuclear fission reactors produce waste products that take thousands of years to decay, the waste products from fusion plants are short-lived, decaying to non-dangerous levels in a decade or two. The desktop experiment is safe because, although the reactions generate extremely high pressures and temperatures, those extreme conditions exist only in small regions of the liquid in the container - within the collapsing bubbles.
Well .. table-top Mr. Fusion seems to be on its way. The small device will now unleash a brand new source of heat with the temperature of a small star. I guess we will have to figure out how to bury it or radiate it out to space. Jeeesh .. MIB police will come by and give us a ticket for inter-planetary warming.

short half-life = highly radio-active?

Sweet, with all this new tech to help geo-engineer ourselves out of problems, I will not feel so guilty going to Belize this fall.
