A friend forwarded me a review of various type of whiskey-chillers, comparing `whiskey stones' made of actual stone to fancier `novelty' types made of steel or other materials--and also to plain old water-ice. The surpising conclusion? "To get the quickest chill, nothing tops an ice cube or two in your glass" (though the little steel containers of liquid also did a pretty good job). Though...., I guess it actually shouldn't be surprising that chillers employing phase-change to cool do it more effectively than the ones that just employ temperature-gradient and heat-capacity--especially when the volumetric heat capacity of the latter isn't really fantastic anyway; consider: Not only does water have a crazily high heat-capacity, but the amount of energy that frozen water absorbs in order to feed the phase-change from solid to liquid is also crazily high (and, on top of all that, remember that water just after melting is the same chilly temperature as ice just before melting; so, first the phase-change absorbs a massive amount of energy from the whiskey, and then the liquified water absorbs another massive amount of energy meeting the whiskey somewhere between 0° C and whatever temperature the whiskey was at when it finished melting the ice). Though, yes: you do end up with some liquid water in your whiskey. And if ending up with water in your whiskey bothers you, then the obvious move is the wrap your icecubes in some sort of impermeable barrier, which is exactly what those `steel with liquid/gel center' do--except, they probably would have worked a lot more quickly if they'd used, say, copper or silver cladding rather than steel; in the culinary and welding worlds, steel is basically known for its lack of thermal conductivity (hence all of the `stainless-clad, copper- or aluminum-core' cookware; nobody in the cookware industry has the guts to try to sell sterling-core cookware, but the welders can tell you all about how difficult it is to work silver without just making a huge mess due to it conducting the heat throughout itself faster than many heat-sources can heat it). Actually, comparing thermal conductivities, diamond cladding would probably be really great. Though, going by the heat-capacity table, it looks like what one really should use to chill one's drink without weakening its flavour is to put a piece of frozen meat into it. [Reply] |

A network tech came to visit with me today, and at some point I mentioned offhandedly:

Apparently people are endlessly impressed by this (this is something like the eleventh such reaction I've got). [Reply] |

Chris Gagnon died on 2014-12-17. I was lucky enough to have known him as a friend and colleague since we first met, at Russound, in 2006. I am different I am better I do things differently He will forever be a part He will forever be a part But, at this moment, [Reply] |

I don't know why this is so difficult, but I have a pretty thorough appreciation for Doc Searls' `intention economy' right now: here I am, ready to buy something. These are my requirements. Something does exist that meets them. I just need to find it. I just want to know the intersection between these two sets:
As far as I can tell (by brute-forcing a solution), these are the devices:
No idea what all of the prices are; how they rank in terms of ease of installation, build quality, or anything else; or what subset of those devices are still available for purchase new. All of those require more digging. [Reply] |
