More importantly, what is in your PhD??
OzOne wrote Lost of incomprehensible BS about a method of cooling. I hope the review committee doesn't find it "incomprehensible" Gilligan wrote: What kind of cooling - phase change, magnetic, electric field, expansion of gases or something else? All the above, of course. He has applied both fuzzy logic & string theory to produce quantum amounts of "fuzzy ice" ... Did you know Einstein invented a refrigerator? I'm interested! Me too. Did you know the first air conditioner was invented to prevent malaria? DSK |

Did you know the first air conditioner was invented to prevent malaria? Quite gillinestic The first air conditioning probably started with early man when he moved inside a cool, dark cave to escape the summer heat and to protect himself from the winter cold. Humans have continually searched for ways to keep cool in the summer, from indulging in Roman baths to siting castles for cross-ventilation to using cardboard hand fans during many summer church services. It has only been in the 20th century - less than 100 years - that air conditioning as we know it now has been in use. Today, we find the benefits of air conditioning to be much more than personal comfort - it is necessary for improving productivity in the workplace, making possible good medical/health service and preserving fresh and frozen foods. In less than 100 years, air conditioning has become a necessity in our lives. Air conditioning - or manufactured air, as it was first called - was originally considered to be simply controlling humidity. Textile mills had a higher production rate if the inside humidity could be managed. Then temperature control was added and - presto - circulated air with controlled humidity and a constant temperature. Joe DSK |

Scout The problem with single frequency sound waves, if they are travelling is that a fixed point along the path experiences both high and low pressures equally. In the case of standing waves a fixed point sees a time varying pressure. The trick in either case would be to move from a high pressure point to a low pressure point quickly or do a frequency sweep. Still doesn't sound practical. Perhaps using a liquid as the medium rather than air and having the liquid go through a phase change. Now it's almost a conventional refrigerator, one is just replacing the compressor. |

Would be nice to see a system that uses water as the refrigerant (besides some commercial absorbers). Scout |
