Only reference I could find was to using ultrasound to keep a steam mix homogenous for making good crusts on bread. You sure this technology exists? |

//for making good crusrts on bread// |

Ultra sonic for domestic pets, but painful and dangerous for non-domestic pets - i.e. rodents, cockroaches, etc. |

Was shown one at a fab a month or two ago. Heats locally, (high temp) used for mini-imprinting and for welding. |

Sonication is used extensively in the laboratory world for cleaning and for sonic disruption of cells and thourough mixing of solutions. Also used to degas solutions for certian types of analysis. You might produce VERY localized areas of heating but this is generally due to the shredding of whatever is being sonicated and the resulting friction Otherwise heating is not something that this process does very well at all. i just dont see this working at all. Sonicators already exist for home use in the applications that the technology is applicable. Other heating technologies are far more efficient and effective. And they dont turn your hamburger into mush. |

Whas iz I non't ave any meeh? |

Sorry but your wrong. [jhom]
will delete until I find the proof, then re-post... |

//Should be ultra to pet's sonic, and should not be confined to inside the "oven"// Any energy source sufficiently powerful to cook food (or other organic matter, like, say, humans) absolutely *should* be confined to the oven. [-] |

I look forward to seeig anything that you find. Always interested to learn new things ;-) |

I use a 20kHz sonicator for lab use. It can heat the hell out of very small viscous solutions. If you want to heat small amounts of ice cream or custard, this would be ideal. [-] |

I've heard of sonic cooling, but is sonic heating possible? |
|
| |
Are you sure you're not thinking of INDUCTION heating? It uses a strong, harmless magnetic field that makes metal very hot. They use it on foil-sealed bottles and stuff. The foil piece is placed in the lid, the lid screwed, then it goes under the induction machine the foil seal welds itself to the bottle. |

GumBob could you give a source? (link or name of manufacturer) Thanks! |

Finally a link after some years. Why all the fishbones? Can somebody who fishboned explain what they don't like about the idea? Its fairly simple. Since in the lab you use a sonicator for miniscule and local sonic heating, why not use the same principle, but in large scale, for heating regular soup, or a plate of pasta?
Its probably safer than microwave. |

I'm made all the more curious by the phrase //strong, harmless magnetic field //. |
